Qemu with kqemu for kernel acceleration is a very workable 
virtualization tool. If I had to ballpark it, I'd say there is no more 
than a 5% penalty without any virtualization extensions built into my 
chip. Without kqemu, qemu it is nearly unusable though.

Also, qemu can convert and use vmware files, or physical partitions for 
virtual machines as well. Worth checking out for desktop 
virtualization.

For server stuff, well I'm biased towards Xen since that's what we use 
at work.
