Redhat's press release in February made it clear, Xen is out, KVM is in.
I wouldn't consider Xen anymore that it is marked an EOL technology.
kvm is much lighter - a mere module to load without a reboot.

I had assumed the full featured aspects like high availability
(server fails, guest hosts are automatically spawned on other servers)
would not be made available in Fedora.

At this point, I've only used KVM on Debian 5, which also has

It is the control and automatic stuff like snapshots and high
availability which we are going to need if vmware is to be
possibly challenged.  Unfortunately,  we may not be
able to wait for the Q2 Redhat release.
