One correction – Proxmox VE absolutely has snapshots. It uses lvm for the backend. The snapshots have to be done via the qemu command line. Its under the “Monitor” tab on the web interface. To take a snapshot, type “savevm “. To load a snapshot, type “loadvm “. In my experience, the snapshot save/restore mechanism is faster than other Hypervisors.

Great article, thank you for writing about this. You have a lot of informative articles here, thanks again! I found a brief primer on Software Testing, do you think it is any good? I'm curious about such introductory articles for someone who is thinking about getting into Testing. Visit my site if you'd like to read more.

Excelente review! I use KVM as my main virtualization platform for non-production systems. At work we use Xen but we’re evaluating new platforms with better tools (as it’s just paravirtualized Xen, not XenServer).

I’ve never heard of ProxMox before but it sound really cool. I will give it a shoot and let you know what I think of it.

Congratulations again!

Great write-up and thanks for following up your previous posting on virt technology. We’re currently evaluating several virt technologies so this is valuable info for us. I’d heard of KVM of course, and OpenVZ kinda vaguely but ProxMox seems to have brought the two together. I did not hear about ProxMox until reading your post. I’m gonna add ProxMox added to the bunch we’re currently evaluating. One thing, the screenshot here appears to show that snapshots via web interface is possible: http://pve.proxmox.com/wiki/Backup_-_Restore_-_Live_Migration – is this true?

BTW a Debian developer who has recently joined our company has been waxing lyrical about KVM and I’m thinking it is now _the_ way to go for future Linux-based virt.

We use Xen at work, it’s pretty good and very efficient. The guests run very fast with little or no overhead. If you want a GUI though to manage it then I’m not the guy to advise other than to probably look at the Citrix Xen product. We use Xen in a hosted environment and manage it and the guests with the command line. It’s totally manageable that way though.
If you hang out on the #xen IRC Freenode channel you become aware of some extremely cool stuff going on in Xen – there is a project called Remus that provides failover for a Xen guest – not only is the disc kept in sync but the memory, TCP conns, everything! It’s aim is to failover as if nothing happended to the original guest. It’s just been merged into mainline Xen and will be in the next release.
I keep hearing good things about KVM – it’s big advantage over Xen is that it’s implemented as a kernel module – thus your KVM machine gets all the mainline kernel updates too. Xen requires a specialized kernel and thus the guests need to be patched to run with that kernel.
Anyhow, keep us updated on which you go with and why – oh, and describe the GUI management stuff too!
