I don't think the VMware architecture is better than PV Xen in terms of
performance for Linux.
In PV Xen, you get no CPU overhead and I/O amounts to exchanging memory
pages between domains. You can't really make this more effective on x86
hardware (including x86_64) IMHO. Besides, by using RHEL virtualisation,
you save money on licenses for the operating system as well.

Subject: Re: [rhelv5-list] ESXi vs Xen
I understand they're stripping the HA and live migration parts. But in
terms of raw CPU and IO performance, is it much better than Xen ?

Do look more thoroughly what they actually are making free.
Might not be
enough for your use.
