Ask Slashdot: Which Virtual Machine Software For a Beginner?

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.

VMware is very easy

[blandcramration]

I honestly just used VMware for the first time today but it was very easy to use and booted up in seconds. You can add virtual drives with a click and if you are anywhere familiar with the operating system you are attempting to emulate, I'd say it's a safe bet. Maybe the community can offer a few free options for you to try out as well.

Virtualbox is a nice entry hypervisor, and certainly if youre brand new start there.... but I wouldnt do anything production on it. I have had upgrades render VMs unusable, though with a downgrade and substantial effort I was able to restore them. Virtualbox has the basics, but it has its bugs. Using it for a few years before moving to Workstation will help you to appreciate when a hypervisor works correctly :)

Its also worth mentioning that if you go to Windows 8, you have Hyper-V, which I understand has started to suck a lot less in version 3.

I disagree. VirtualBox is not unstable. In fact, I think it is perfect for a beginner. It is free and if you grab Gentoo Linux, you would be learning a lot of just about everything. 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 works right out of the box with no user manual even needed. That's already more than can be said for any of the competition.

Not so sure about that last sentence there.

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.

VirtualBox

[Anonymous Coward]

VirtualBox is the best for a beginner. User-friendly GUI, sane defaults, it Just Works.

VirtualBox Certainly

[mqhiller]

Easy to set up (I walked my brother through it over the phone) easy to use (ditto) and fairly full featured.

Virtualbox

[BuypolarBear]

Virtualbox is pretty reliable and includes acceleration on 64 bit systems along with an extremely simple to use GUI and easy to install guest additions that allow your display to easily scale. It's the one thing from Oracle that I actually use and recommend to others. For your requirements, it's licensed under the GPL v2 and works on Windows, Linux, and Mac.

VirtualBox or VM Workstation

[PraiseBob]

VirtualBox is the easiest free option to get started.
It can run inside a host OS, so you don't need a bare metal install, and don't need a web interface to use it.
It has easy to install and operate clients in Windows and Linux (can't speak for Mac).
It can build VM's easily. (VMWare free options cannot create VM's)

If you are willing to spend a little money, the VMWare Workstation is more powerful and offers similar features to those above, but better resource management in general.

Re:VirtualBox or VM Workstation

[SilentChasm]

Your knowledge of VMware is a bit out of date.

VMware player can create virtual machines (and has for some time) and it is still free. It works well on Windows and Linux hosts.

Hyper-v in Windows 8

[sofakingon]

I've been working with VMware since ESX 3.5. It's still my virtualization platform of choice, but on my desktop, I now run Hyper-v. It's included as a role in Windows 8, and is painless to install and configure.

Re:VMware is very easy but

[DaveAtFraud]

VMware tends to be fussy about the hardware. I had a non-descript Athlon dual core that ran VMware just fine but lacked horsepower and wa maxed out on RAM at 4GB. I decided to buy a 6 core Athlon, new motherboard and 16 GB of RAM. VMware installed just fine but the clock drifted all over the place (several seconds per minute). Finally gave up on VMware and went Xen. Xen worked just fine but lacked all of the nice management tools and virtual networking stuff that VMware had. SIGH.

Also, it will only install if you have a supported network card in your target box. Check the hardware requirements.

If you want to try VMware, there is a free version: http://www.vmware.com/products/vsphere-hypervisor/overview.html

Oh yeah, one other downside of VMware is the management console only runs on Windoze (at least when I was using it about a year or so ago). You will still need a separate, standalone Windows box

Cheers,
Dave

Re:VMware player

[Golden_Rider]

The free hypervisor is here: http://www.vmware.com/products/vsphere-hypervisor/overview.html

You'll need a license key, which you can also get (for free of course) on that website.
