I see this a huge mistake on the part of RedHat.  Only Type-1, 
bare-metal virtualization, such as Xen makes sense for enterprise 
deployments.  Sure, if you want to provide the Linux desktop user with 
some virtualization then KVM might make sense.  But RedHat is losing 
ground in the desktop arena already so why bother.  You have major 
players such as Amazon that currently use RedHat and Xen bare-metal 
virtualization in their public cloud offering.  You have complementary 
private cloud technologies such as Eucalyptus which also support Xen so 
you can mirror Amazon.  And I see that trend growing.  Once a distro 
like RedHat can use a dom0/domU shared kernel (which hasn't been since 
F8 and probably drove them to purchase Qumranet) then Xen usage for even 
the casual desktop user becomes much easier.  The new pv_ops kernels are 
now providing just that possibility once again.
