Hi , guys, I have found in Fedora 10 Features , that there is still a lot of work to provide xen kernel with dom0 support to Fedora 10 GA. For my future project, which at 90 percent depends on virtualization technology I am deciding between XEN or KVM virtualization. I am experienced XEN user, KVM is new for me. But as I am aware of, Qumranet was bought by RedHat which predicts something ...
There is pretty much zero chance that Fedora 10 will include a Xen Dom0 host. While upstream Xen developers are making good progress on porting Dom0 to paravirt_ops, there is simply too little time for this to be ready for Fedora 10. So if you need to use Fedora 10 as a host, then KVM is your only viable option at this time. If you can wait for Fedora 11 (or use RHEL-5 / CentOS-5) then Xen may be an option for you. I'll let other people comment on the pros/cons of Xen vs KVM outside the kernel availability issue.
