Suggested March 2024 Ubuntu Virtual Machine: Guest And Host

If you’d like to run an Ubuntu virtual machine on your PC, you’ll need to weigh a series of considerations. To be sure, the use of virtualization is commonplace in the IT industry these days. Still, before you decide to run an Ubuntu virtual machine, you must consider whether you fully understand the benefits of setting one up in the first place.

In this article, I’ll explore virtual machine hosts and guests on Ubuntu, why virtualization is a better bet than relying on WINE and how to ensure that you are selecting the best virtual machine solution for your Ubuntu desktop.

Generally speaking, it makes very little sense to run a virtual machine of Ubuntu under Windows. If you’re relying on Windows and looking to run Ubuntu also, it would make much more sense to look into a dual-boot environment or consider using the Windows installer for Ubuntu. An alternative to using the Ubuntu Windows installer would be to use a bootable USB drive loaded with Ubuntu already. This is useful in that it would provide you with a dynamic Ubuntu experience without ever needing to touch your existing operating system’s installation.

For most people, Ubuntu makes for a great host operating system, and running Windows as a guest provides the best value overall. An example of this would be if you needed a legacy Windows application, but would rather use Ubuntu as your default operating system. Using an Ubuntu PC with ample CPU power and RAM, you could run an instance of Windows and access the legacy program under Ubuntu quite easily. Depending on the virtual machine software you decide to use, you could even run your guest desktop in a “seamless” mode where the guest OS’s software visually appears to be running natively on Ubuntu.

In order to setup an Ubuntu host with Windows running as a guest operating system, I recommend the following:

Use a PC with ample resources. I recommend using a computer with as much RAM and CPU power as possible. Ideally, I prefer to give a guest operating system like Windows 2 GBs of dedicated RAM to work with, with at least another 2 GBs of RAM for the host operating system.

Consider whether running a virtual machine is the best approach to using multiple platforms. If you’re looking to play video games in a Windows guest on an Ubuntu-host PC, you’re going to be very disappointed. When it comes to running video editors, video games and CAD programs, you really need to consider a native operating system environment. Trying any of the above with a virtual machine isn’t going to work well at all.

Consider whether using an open source software title be a better alternative. In many instances, using an open source software application will provide the same results as using a proprietary Windows application. While some users will disagree with this, it has been my experience that in many cases open source alternatives can offer most if not all of the functionality found in proprietary software. After doing some initial testing, you may discover that you could be using a natively supported open source application. This would mean that you could avoid relying on a virtual machine altogether.

When it comes to choosing the right virtual machine software for your Ubuntu installation, you must first decide which factors matter the most to you.

Difference Between Host And Hostess

One of the significant discussions that have been on the rise is whether the terms host and hostess can be used in place of each other. The word Jody generally has varied applications and makes distinguishing them challenging.

One example we can see here is event management, considered a professional work genre. Among the other delegates, the hosts play an essential role in the success of both big and small events. The host’s professionalism depends on the parties, and there are special training schools to establish oneself as the host or hostess.

However, when we take a deeper look at each of the applications, they may shed light on what each stands for, and the difference between the host and the hostess is not just limited to gender.

Who is a Host?

The word host is said to be an umbrella term that includes all activities that are attributed to the person hosting an event. Although the word host sub-categorization is male and female, a host is commonly attributed to a male person who indulges himself in hosting different activities. A good personality always acts as a plus point to a suitable host; the host is chosen based on skills like the entertaining nature, reliability of the content spoken, etc.

A host might be the guest at some parties, and vice versa. This interchangeability of the roles plays a vital role in maintaining a rapport and initiating friendly relations. The word host, when used as a verb, indicates the act of managing the party when the guests arrive. When used as a noun, the word host refers to a male host only who is expected to drive the events based on the agenda.

The term host has subjective interpretations as well, and it can take on different definitions based on the application like −

A host is someone who receives the guest and entertains them for commercial and other official purposes or socially.

A host might also be someone who facilitates a function or an event and provides facilitates for the same.

A person who engages guests in a TV show or a radio program is also known as a host.

Who is a Hostess?

The term “hostess” is attributed to feminine features only, and no male can identify himself as a hostess, irrespective of the specified group of activities assigned for an event. The term hostess is commonly referred to a female flight attendant host; this is an exclusive post for females most widely referred to as an air hostess.

Special examinations and strict training mode take place before the selection of the hostess. The term hostess is attributed in two ways, one where the female hosts events and two to serve as a flight attendant throughout the journey.

The term “hostess” has many definitions based on its usage, including −

A hostess is paid to entertain guests or one who does it socially.

A woman in charge of seating diners in a public room is also referred to as a hostess.

A hostess is also employed on a public conveyance in cases like a flight attendant who caters to the needs of the passengers.

Differences between Host and Hostess

The main difference between the host and hostess is that the former is a male and the latter is a female; both these terms emerged when there was a need for assistance in the field of event management. The following are some more differences between the host and the hostess other than the gender.

Definition

A host is an individual who is expected to act as the representative of a party in front of the guests, the organizer of the party may also be but is female, with similar code

A host usually wears tuxedos in a formal gathering, and their attire traditional clothes and western management and extracting manipulating, serving food, and catering to the needs of the reliability

Hosts are usually preferred for large gatherings may be due to gender for traditional gatherings and gender, but they share many roles now. This plays for both the host and the hostess, and everything a host does, a hostess does too. The host and hostess invite guests, welcome them, provide them with food and drinks and entertain them. There has been a rise in the sharing of jobs between male and female workers. Hence, the role of the host is no longer reserved for the women or the hostesses only.

Both the host and the hostess work in unity for the active incorporation of all types of traits; whether or not it is a party or a business meeting, the management needs to delegate the work of hosting the people effectively to a good host. Apart from this, the host and the hostess are present to cater to the needs and queries and should have apt knowledge regarding the invitees for extra reference.

Enable Integration Features For An Xp Mode Virtual Machine

Available in Windows 7 Professional, XP Mode allows you to integrate your physical computer’s resources with a Virtual Machine. Components you can share include drives, audio, printers, Clipboard, and smart cards.

Learn how to enable and use the integration features of an XP Mode Virtual Machine.

Why Enable XP Mode Integration?

An XP Mode Virtual Machine uses your physical computer’s resources to run a fully licensed copy of Windows XP right from within Windows 7 Professional.

Part of your computer’s RAM, processing power, and other components are used by the Virtual Machine to allow XP to run.

Using XP Mode’s integration features, you can also share other resources such as drives, audio, and printers to increase the functionality of XP running in the Virtual Machine.

Enabling and Using XP Mode Integration Features

Note that the right hand side of the window changes to show you the integration settings available for your XP Mode Virtual Machine.

On the right side of the window, you will notice several options. Below is a description of each and some hints on how to use them to make your XP Mode Virtual Machine more integrated with your physical computer.

Enable at Startup – This option allows you to specify whether the integration features are available each time you startup XP Mode. Unless you want to manually integrate each feature when you use XP Mode, leave this option checked.

Audio – XP Mode can use your PC’s audio to add sound to your Virtual Machine sessions. Keep in mind that integrating audio adds one more component that can go wrong. If you really have no need for sound while using XP Mode, leave this option unchecked.

Clipboard – Integrating the Clipboard with XP Mode means that text, images, or other elements can be cut, copied, and pasted between your physical PC and the Virtual Machine running XP Mode.

This is one of the most useful integration features. Consider enabling it if you need to share documents quickly and easily between your PC and XP Mode.

Printer – If you plan to print from within XP Mode, check this option. Using printer integration, XP Mode will treat your printer as if it were connected directly to it rather than to your physical PC. Most people find that integrating the printer is essential to get the most from XP Mode.

Smart Cards – If you have any smart cards connected to your PC and you want to use them in XP Mode, you must check this option. If you have no smart cards, leave this one unchecked.

Drives – This option lets you specify whether all drives or only the ones you choose are integrated with XP Mode. At the very least, make sure you integrate the drive on which Windows 7 Professional is installed (C drive for most people). This way, you have access to your user account, desktop, My Documents folder, etc. while in XP Mode.

Windows 7’s Virtual Machine technology allows you to integrate and share the resources of your physical PC with XP Mode.

By doing so, you can gain access to the drives, printers, smart cards, Clipboard, and audio features of your PC. Luckily, the Virtual Machine lets you select which components to integrate so you can make your XP Mode sessions more streamlined and less complicated.

Dual Boot Vs. Virtual Machine: Which One Is Better?

Software developers, testers, and those of us who evaluate and document software applications often need multiple environments.

We might need to test applications on different versions of Windows, macOS, and even Linux. Due to budget constraints, though, we can’t often have another computer available for each environment.

Two options let you work in separate environments without purchasing separate machines.

The first is to set up your computer with dual-boot capability. This allows you to set up multiple operating systems on one device and choose which one you’ll use when it boots up.

The second is to use a virtual machine, also known as VM. Virtual machines are kind of like running a computer within a computer. They actually run in a window on your device and can have the full functionality of the computer and operating system you want to use.

Why Do We Need Multiple Operating Systems?

So, why do developers, testers, and others need multiple systems? Why can’t we just use whatever we have available to us?

It’s vital for software to run smoothly across platforms. It’ll make the product available to more users, not just the users of one type of system or environment. In the end, that means more customers—and more money.

Because of this, developers, testers, and evaluators need to have multiple operating systems available to them. It ensures they can design, develop, and test the software in each type of environment.

A developer may do the majority of his or her work on a Windows OS. However, he or she might then need to make sure it works on macOS. Testers and evaluators will also try the application on both systems to see how it performs on each.

Aside from software development, some people just like to use more than one type of system. They may prefer certain features of Windows but also desire other features of macOS or even Linux. In this case, a person can have access to all of them without multiple computers.

You might also have software that only works on one platform but enjoy using another for all your other tasks. Finally, you might need different versions of one operating system, such as Windows 7, Windows 8, or Windows 10.

Which One is Better?

Two methods can be used to boot multiple operating systems on a single machine. You can set up your computer to have dual (or multiple) boot capability, or you can also use a virtual machine to emulate another operating system. So, which one is better?

The answer depends on your needs and preferences. Let’s look at the benefits and issues of both methods.

Dual Boot: Pros & Cons

When it comes to dual boot, here’s what we mean: completely separate operating systems on different partitions of your hard drive, other hard drives, or removable media. Once the system starts up one OS, the computer and its hardware are wholly dedicated to it.

This works well if you have a computer without a lot of memory or processing power. It means all of the computer’s resources are dedicated to just the environment you boot up in. You can still have decent to great performance with each OS installed.

Another problem is that you will not have the ability to work in both systems simultaneously. While this may not be a problem for the casual user, it may make it difficult to compare and record results as a developer or tester.

Virtual Machine: Pros & Cons

Using a VM is like running a computer in a window within your computer. Virtual machines are powerful and give you many options.

You can be working in your host machine’s OS while another virtual machine is running separately in a window on your desktop. This makes it easy to switch back and forth to test or perform any functions you need.

You can also run more than one virtual machine, but it may require a powerful computer to do so. Virtual machines can also be created quickly; if you’re no longer using them, it’s easy to delete them.

If you have a specific configuration you need to test with, you can create a base machine, then clone it whenever you need a new one. Once the VM gets cluttered or corrupted, you destroy it and clone another one.

Working with virtual machines does not require rebooting your device. Instead, you run a hypervisor, which runs the VM and instructs it to start the OS you wish to use.

Since VMs use and share the host machine’s resources, they can be slow and even on occasion freeze up—especially when trying to run more than one at a time. They may also slow down the host machine itself. For these reasons, VMs do require a good deal of management and administration.

The Verdict

As you can see, which one is better depends on how you will be using multiple platforms and what type of hardware you have to run them on. I recommend using virtual machines for anyone who has a computer system with good to excellent disk space, memory, and processing power.

If you have a less capable machine, dual boot can work beautifully. The downside is that you can’t switch between operating systems or use them simultaneously. You will have the luxury of devoting your computer’s full processing power to each OS.

If you feel that virtual machines will work best for your needs but don’t have a lot of processing power available, you can use VMs hosted on remote servers or in the cloud.

Companies like Microsoft and Amazon have paid services that allow you to create and use multiple VMs that they host. It can be nice when another company is responsible for maintaining the host machines and hardware. It can be a load off your mind, freeing you to create and use VMs as you need them.

Final Words

Deciding between dual boot and virtual machines can be a difficult decision. Both methods are great ways to access multiple operating systems and environments without the need for separate computers.

We hope that this article has given you some insight and the knowledge you need to help you decide which one will work best for you.

Linux Leaders: Debian And Ubuntu Derivative Distros

By any standard, Debian is the most influential Linux distribution ever. Not everyone uses Debian, but, both alone and second hand through Ubuntu, it is the source of more derivative distributions than any other.

Or, to give a different metric, of the 323 currently active distributions listed on Distrowatch, 128 are based on Debian, and another 74 on Ubuntu. In other words, just under 63% of all distributions now being developed come ultimately from Debian. By comparison, 50 (15%) are based on Fedora or Red Hat, 28 (9%) on Slackware, and 12 (4%) on Gentoo.

Given these figures, it is not surprising that Debian should have its Derivatives Front Desk and Ubuntu its Derivatives page to track their relationships with other distributions. As incomplete as both these efforts at keeping track currently are, they are still additional proof (if any is needed) of Debian’s and Ubuntu’s far-reaching influences.

Start scanning the lists of derivatives, and you will find something for everybody, from general purpose deskstops, Live Media, alternative interfaces, netbooks and other platforms to compact installations, localizations, security and privacy, and multimedia.

Debian was the last of the major distributions to get a user-friendly installation. To fill this gap, many derivatives sprung up, including Libranet, Stormix, Progeny, Linspire and Corel, all of which became defunct long ago, due to major changes in the Debian Installer and to Ubuntu’s basic installer.

Another all-round distribution is gNewSense. Its main claim to fame is that it is a completely free distribution that carries no proprietary software whatsoever. In fact, of all the free distributions recognised by the Free Software Foundation, it is by far the most polished and usable.

One of the oldest derivatives is Knoppix, which is also a pioneer of Live Media — CDs or DVDs from which you can boot a computer without accessing the hard drive for secure computing or for demoing software. For many, Knoppix remains an essential tool, especially as a rescue disk.

In fact, Knoppix is so popular that it has evolved its own derivatives. These derivatives include kademar and KnoSciences, both of which have more extensive hardware support than Knoppix, the clearly named STD (Security Tools Distribution, and VMKnoppix, a sampler of virtualization alternatives. Like Knoppix itself, these third-generation derivatives can be used from an external drive or installed on a hard drive.

Debian has a long tradition of including alternative desktops and window managers in its repositories. Similarly, Ubuntu includes a class of what it calls “recognized derivatives” that it considers part of the project, and which includes Kubuntu (KDE) and Xubuntu (Xfce).

However, these are by no means the only interface alternatives. If you install Bodhi, you can work in Enlightenment, the window manager that borders on being a desktop. Alternatively, Damn Small Linux and the dormant Fluxbuntu both use Fluxbox as a window manager. If Fluxbox doesn’t fit your needs, then perhaps CrunchBang and Openbox might instead. Still another derivative that has received considerable attention in the past year is Lubuntu, which uses the lightweight LXDE desktop.

Although they have not been universally popular, developing a desktop for netbooks has been a main concern in free software for the last few years. Of course, Ubuntu itself is developing the GNOME-based Unity for its main interface, a project that was originally called Ubuntu Netbook Edition, but you can find no shortage of netbook-centered derivatives, either.

Most of the netbook-centered choices are based upon Ubuntu, and emphasize social media and cloud computing. They include Aurora (formerly Eeebuntu), Easy Peasy, and Jolicloud.

The history of Debian and Ubuntu is riddled with derivatives that briefly attempted ports to other hardware platforms before being discontinued. These include BlackRhino, which ran on Sony Playstation 2, and a number of derivatives designed to run on Openmoko’s Neo Freerunner.
