Since the Xen and Linux kernel people have finally made peace and Xen is going to be included with the kernel, should I keep using the Xen virtual server with Centos or should I switch to KVM? I am running Centos 5.7 now. I guess the real question is can I still use Xen with Centos 6?
The support end of life for CentOS 5 is listed as March 31, 2014 (http://wiki.centos.org/FAQ/General#head-fe8a0be91ee3e7dea812e8694491e1dde5b7...). There isn't any pressure, at this point, to convert your VM hosts to CentOS 6 unless there is some feature you require.
I doubt RH will add XEN support to RHEL 6. They don't like to add functionality to an existing product. We can hope they bring XEN back in RHEL 7.
There was some discussion about producing RPMs to add XEN support into CentOS 6, but I haven't seen any status updates, recently.
