I've used lots of different versions of VMWare Workstation, Player and Server; on Linux and on Windows. I tried to give V-Box a shot ... but, frankly, for virtualizing large apps that need to run on Windows Server ... VMWare is more robust, more reliable and performs a lot better. VMWare is the clear winner in my book.

IMHO .. PSM

I have tried VMWare and VirtualBox. The latter gets my vote. It works well with Ubuntu.

VirtualBox!

I bought VMWare Workstation a few years ago (starting at v4.5?), but everytime I upgrade it, it fails to compile it's driver. Then I have to download some any-any thingy or plow around forum sites looking for someone that knows what source file to tweak to get it to compile. Right now I can't run it at all.

But no problems with VirtualBox.

Right now, I have Windows XP, FreeBSD 7.1, and OpenSolaris 8.11 running in virtual machines on my Mandriva Linux Host. I have 3GB, so each of the four (including the host) gets a little less than 3/4 GB.

Fun stuff.

I was glad to see some mention of KVM, but was hoping to hear more success stories with it.

It's description makes excellent logical sense and I've been expecting to use it, but I've had limited success so far.

KVM is pure awesome and win.

Virtualbox and vmware second.

vbox first and free(so far...)
vmware server (could they get just a little cheaper?)
qemu is third.

as for xen or kvm, have yet to try/test them.
parallels, doubt I'll ever put it on my box.

VirtualBox is ... no negative so far.

VMWare has my vote!


debian

...since we have been using KVM where we can, and QEMU where the CPU lacks the virtual hooks.

It should be time for another poll soon, no?
