Ask Slashdot: Which Virtual Machine Software For a Beginner? 361
An anonymous reader writes "I am getting ready to start learning the use of virtual machines. What VM software would you recommend? This is for personal use. It would be good to run both Windows VMs and Linux VMs. Early use would be maintaining multiple Windows installs using only one desktop computer with plenty of cores and memory. I would be starting with a Windows host, but probably later switching to a Linux host after I learn more about it. Free is good, but reliability and ease of use are better. What is your preferred choice for a VM beginner? VMware? Xen? VirtualBox? Something else?"
It may also be helpful if you can recommend particular VM software for particular uses, or provide some insight on different hosting options.

After you are done with VirtualBox you should really get into kernel hypervisors. That's about it. No vmware needed, or paying for software in the learning process.

VMware is easy to use and is free, as in beer. One of its strengths is that virtual disks can be moved about and that makes it easy to create virtual appliances. There're a ton of them out there on the net, mostly Linux distros tailored for a specific use. I've fooled around a bit with VBox and it's OK. Its performance is not on the same level with VMware. Or you could try Zen. Or attach electrodes to your feet like they did to Ham.
For me, as a desktop Linux user, VMware has been the mac-daddy killer app. There's not much reason to boot to Windows these days except for games, and I've found that what won't run under wine will usually run in VMware with a Windblows guest. Also, there were some kernel taint problem associated with VirtualBox that've been probably fixed by now.
On the other hand, if you're planning on running OS/2 in your guest, then Vbox is the only way to go! I learned that a couple of months ago.

I trained a new hire to use VirtualBox on an Ubuntu 12.04 box this week. He had just about zero experience with virtualization. Basically my instructions were to have installation ISOs for whatever OS he wants to run virtualized and to apt-get install virtualbox. He then set everything up on his own and only asked for help when it came to setting up a virtual network. I told him he should first figure out cloning. A few minutes later we were back on the virtual network. My own experience a couple of years ago was similar. In both cases, we had the manual handy, but never used it.
My proficiency with KVM/libvirt took more effort. But virt-manager makes it pretty straight-forward. Our KVM/libvirt virtualization system has several host nodes running a few dozen guests with storage on a SAN/NAS (it does both). This wasn't painful to do at all. An automatic backups/snapshot system has been more challenging, but that's mostly just because we want to minimize interruption of the guest (just suspend the guest, grab an LVM snapshot, wake the guest, copy the snapshot, free the snapshot) and due to our larger guests being about 200GB in size. Storing versions of files that large, and moving them around, requires delta compression. (Hint: Use xdelta3 before copying the data off-site.)
We also played with Proxmox a few months ago. A summer student had all of the above (except for backups) working in two days. Confusion over whether the licensing was really free, the fact that it is its own distribution (a double-edged sword for sure), and the fact that configuration of aggregate network links (LACP) was really goofy, all kept us from adopting it. Too bad, being able to switch a guest from one host to another in real-time while viewing the guest's display with only a tiny pause, was a really neat trick.
If I can do the above mixed in with all of my other responsibilities (as a school authority director of tech), anyone can.

Likely this only increased the size of the virtual disk, but not the partition that the OS lives on. Partition resizing is file-system-dependent as it requires understanding the FS layout. gparted can do the job if you boot from a live CD, but it'd be simpler to just start over since the OS is screwed up anyway.
BTW, VirtualBox defaults to dynamically sized disks that only take up as much physical space as is actually used by the guest OS. The allocation size is more of a maximum size, so you can safely set it higher than you think you'll need and not waste space.

Virtualization is pretty easy in practice. Understanding the theory behind virtualization is what tends to separate the men from the boys. Management of larger virtualization infrastructures, storage, etc... Also tend to be pain points.
I've personally worked with KVM, Xen, and various VMWare products. My usually recommendation is to start with the free version of ESXi available for download from VMWare's website. Although ESXi alone lacks a few core features (you need Vsphere for live migrations, right-click cloning, DRS and a bunch of other things) it does introduce a lot of the core concepts in ways that are fairly easy to wrap your head around.
Understanding how to do the following things are a good start:
- Use over-commitment to make better use of available resources.
- Set reservations, resource pools, and shares to keep critical systems humming along when someone in the engineering department decides to write a fork bomb on a dev machine.
- Live re-size disks.
- Manage virtual switches & virtual networking.
- Optimize virtual guests to run under a hypervisor
- Learn about ballooning, swapping, page sharing, etc.
- Learn how to monitor VMs, and debug disk/network/cpu/memory issues using command-line utilities, such as esxtop.
In general, ESXi is a great way to setup a virtual lab. I usually create a pair of virtual switches; one attached to my ethernet interface, one strictly external, and I route between them using a dual homed firewall distro, such as ZeroShell. This is a great environment for playing with DHCP, and other stuff that could break your home network.
For what it's worth, being a good Virtualization admin usually also means being a good storage admin. If you can get your hands on the netapp simulator, it's absolutely worth playing with.
Finally, knowing how to mess with ESXi does not make you a good Virtualization Admin. Read some books. Mastering Vsphere 5 by Scott Lowe is a good start. It covers everything you need to know about VMWare, and hits on storage and networking as well.
Finally, while ESXi is a great tool for corporate use and to learn virtualization theory, I strongly recommend gaining some experience with KVM. If you know what you're doing, KVM is much more powerful than the stand alone ESXi product. It's great for small businesses, or business that are banking on open source infrastructure, since it isn't artifically neutered the way standalone ESXi is, and doesn't have major licensing costs (unless you insist on RedHat Enterprise Virtualization.) If you need something with enterprise management capabilities and don't mind deploying bleeding edge code, the upstream project for RHEV is available on Fedora.

VMware: Probably one of the easiest to get set up and master. Dead simple point-and-click interface. Learning this is good if you want a career in virtualization because it is the yardstick by which all others are judged. There are a lot of features though that are disabled in the free version that are used in corporate environments... but you'll have the basics down.
Hyper-V: Also very simple to use and manage... but unlike VMware means you can run it as a side-piece on your existing Windows box rather than having a dedicated piece of hardware just for virtualization. Already built into most modern Windows variants, and used somewhat regularly in corporate environments. Again, paid adds features and support.
Citrix XenServer: Takes the basics of the open source Xen and adds a pretty damned nice GUI. Paid version adds support, but most of the major features are available and functional in the freebie. Trial versions of everything are available. Memory management out of the box is a bit of a pain (no overcommitment by default) but easy enough to modify. Use in corporate environments tends to follow people who have significant Citrix/XenDesktop infrastructure.
Xen (Open Source): By far the best to learn EVERYTHING about how virtualization actually works, but probably the worst for actually getting running VM's. There are GUI tools to simplify it, but since Xen is currently moving to a new toolset that is incompatible with most GUI interfaces, and the GUIs tend to be a smidge buggy on occasion it's usually easier just to learn the command line. Of course, then there are config files, XML files, bridged network interfaces. If you want to learn about the internals this is the way to go... but if you're only going to dedicate a day to trying each one then you might want to skip it... this one will take a couple of days at least even with the several well-written HOWTO's. Having said that, once everything is working it's really nice and you can turn around and say that you know how virtualization works, instead of just saying you know how a single product works!
VirtualBox: Like VMware is good for the beginner to learn the basics because it does have a nice GUI that guides you through everything. Update notifications are a constant irritant though; it seems that every week they're releasing an update for this bug or another... I turn that off and upgrade when I feel like it! However, use in corporate environments is almost non-existent. Good support for most OS's, and decent support for 3D graphics and the like but still pretty kludgy. I use it on my Mac for running my BootCamp partition while under OSX... mostly so I can access stuff on that installation and run updates and the like without having to reboot OSX.
I broke out the two main versions of Xen because they are significantly different. They are similar at the core (based on the same code) but Citrix has it own front-end tools that are incompatible with the tools you'll use under open source. However, the commands are the same and so learning open source Xen will have some bearing on using Citrix Xen.
Of course, there are plenty of other hypervisors out there. My personal recommendation if you just want to play would probably be Hyper-V or VirtualBox. VirtualBox has the advantage of being cross-platform; I don't know if you run Linux or Windows (or OSX) at home, and obviously Hyper-V is Windows only. If you really want to learn virtualization and how it works, then open source Xen is the way to go... I run it on my Ubuntu 12.04LTS box and love it... but it's not for the faint of heart! Setting up the networking alone can be "fun" and you should definitely familiarize yourself intimately with how to undo what you have done so you don't break anything! VMware like I said is used extensively in corporate environments... so if you want to pursue it as a career I'd recommend dedicating a box to an ESXi server and just play with it. It's free and easy... but really doesn't teach much in my opinion.

Ya, that's what I tell anyone that asks me anything. There was a time when you could count on experts helping out to save you some time or to get you started on a complicated area that you weren't familar with. In fact, there use to be computer clubs where information was shared. I guess that time is gone.

Sometimes a smart person will ask a simple question, not because he needs the answer but because he feels the discussion will be instructive to others, or yield useful new insight. /. being a herd of nerd there will be many and apposite solutions and viewpoints offered. This is a legitimate Ask Slashdot question and should come up every year.
Having praised the question I probably should give an answer: "yes".
And since I've been accused of being cryptically terse here recently I should expand on that. All the major virtual machine platforms are free. A learner who wants to understand the relative merits can and should try them all, read, ask and participate in online discussions about them. Learn about the numerous available virtual appliances free and commercial as well. In the current environment VM proficiency is a basic systems admin requirement.

I've been using VMware at work for quickie testing. Seems to work well for this and the licensed copy allows snapshots which are very nice. I understand from developers doing work for us that they run into issues with VMware workstation when they script things to happen with the VMs. VMware player works okay for home use as Workstation is a bit pricey.

The culmination of knowledge on the internet should not be a bunch of people telling you the answer. Expert systems and other forms of AI make it easier to look up the answer (i.e. google) which should see, if nothing else, a reduction in basics questions.
Unfortunately this is not the case and there is a particularly large rise in questions like this - particularly amongst the currently-in-school generation of "first world" learners. My citation? Every day experience consulting into schools for OLPC-style deployments.

I think the first post seriously contaminated the discussion.
I, for one, but have loved to read the opinion of people actually using such software and their experience with it.
I have no need for VM, but I think the opinion of those using it, in many different settings, is much more valuable that any wiki entry or manual.

There's two reasons newbies might need help - the documentation is not up to scratch (or not newbie friendly), or it's a hard problem with no real solution.
"What VM" is, I think, the second case. Postgres and MySQL are both fine databases, but have different strengths. SQL and No-SQL both have merits. KDE and Gnome are both fine desktop managers. VIM and emacs can both edit text.
Sure, there's differentiation, but there's no easy way to say which is best. My advice would be to just look for the one with the best documentation, because as a newbie that's your biggest problem.

Not all of us live in our mother's basement and have unlimited time.

The vitriol that comes out of some people when you dare to suggest that they can handle something independently is amazing.
It's not so much offense at the thought that they can handle something, it's usually offense at the tone used. "Can you not think?" isn't a suggestion that the questioner can handle something independently - it's a blatant insult. As is insinuating that the reason they're asking the question is that they want to put the people they are asking the question to into a subservient position.
You'll be told how smug and elitist you are
"Have you tried Google? Usually it's very good for these sorts of questions." - Telling someone they're competent enough to handle things on their own.
"What kind of fucking moron are you? You're a worthless, conceited human being. Don't waste my precious time." - Smug and elitist
It's really quite an easy difference to pick out, if you're looking for it.
Basic literacy and a few minutes are the only resources this person would need in order to answer his own question.
No, not even close. He's looking for advice for which virtualization software to try. How many different packages are there? How long would it take to read through the manual for each? How long to install each, and give them a decent run through? It's going to be more than "a few minutes".
And that's ignoring the fact that there's likely to be "gotchas" that are going to pop up with advanced usage. How long will it take to learn that program X has architecture issues that only crop up under condition Y? There's also other issues that wouldn't come up in a brief perusal of marketing literature/manual: Is the company going into bankruptcy? Is there a bias against the platform (for whatever reason) in the industry? Is there some kickass new program that somehow escaped the questioner's notice?
Prove me wrong. Point to one or more Google searches (using only the terms in his post or similar - remember he's new at virtualization, so he doesn't know all the jargon), or one or more web pages or manual easily found from the information in the post (e.g. the VirtualBox homepage is fine, but don't assume he knows about expert blogger X who's unknown outside the field) which will tell him what he needs to know, at the quality one would likely expect from asking a site of experts. That is, the pages should give a good, relatively unbiased evaluation and comparison of of various virtualization software packages, focusing on the questions of reliability and ease of use. It should also point out potential gotchas and the features he should be looking into but might not be. And remember that you specified "a few minutes" - all of this information should be readable in less than half an hour.
The annoying part is that everything I said above is straightforward ... and someone's self-importance will be offended by it.
Ironically, I'm most offended by the smug self-importance that infuses your post. "I've got things figured out, and you're horribly misguided. I'm living a decent life, while you are intellectually lazy, entitled, and lacking introspection." - it might not be the tone you intended, but it's the tone that comes across.
Perhaps they will twist what I said to insult me in some manner ... That would be most boring and unsurprising
So to keep from boring you, I'm supposed to point out why what you said was wrong, without actually pointing out what was wrong about what you said ... while such a post would be very interesting, I'm sorry I must disappoint you.

I had a long conversation with a man I consider brilliant (at least in the area of causing people to be extraordinary.) I listened to him speak about "Being Nice" as distinct from being gracious or compassionate. We (most folks) be nice so people will like us, so people will think well of us, as a function of social survival. The people who're truly dedicated to the greatness of others, are to a person, not nice. Watch professional coaches, when they need to be supportive they are, when the need to apply brute force to knock the crap loose, they do, when the thing that is required to make a difference is, in your face rage, they will be in your face shouting. The funny thing is that nice people garner like. The hard-ass straight-up people who would rather take a spit in the eye and make you rise to the occasion than all the kind words under heaven, garner rabid dedication and respect.

Look, the guy asked:
"I am getting ready to start learning the use of virtual machines. What VM software would you recommend?"
You then dump on him with a great deal of pontification simply because he asked for opinions. What the hell is wrong with you?
What, pray tell, is the purpose of education if each person has to find out everything by themselves, and no one can take advantage of the collective wisdom of society, and the accumulated learning built up over history?
Is each child destined to be run over by the first car they see, or burned by the first fire, cut by the first knife they encounter simply because asking for advise, and by extension, giving any, is somehow a shameful act?
Asking questions and collecting opinions is how humans learn. Since you apparently woke up one morning and found yourself an infant laying in the weeds, and proceeded to educate, cloth, feed, and raise yourself alone, with no help from society, I'm left with one question: What species are you?

At first this will be for personal use, but with an eye towards understanding their use in a business environment at the SMB level.

I'd suggest that you try the demos for Fusion and Parallels, see if either is worth the cost or if the free alternative works well enough for your needs.
The original poster's going to start out using Windows as the host, and possibly switch to Linux later, so "VMware Workstation" rather than "VMware Fusion" is the name of the product they want to look at. For Parallels, it's Parallels Workstation (rather than Parallels Desktop, which is the version for OS X hosts).
Other than that, yes, try demos - and bear in mind that, for the non-free-as-in-beer version, switching from Windows to Linux as the host may mean buying another copy.
