Red Hat prefers KVM to XEN! No doubt!

It's unbelievable but it's true! Red Hat in cooperation with AMD performs virtual machine live migration between different platforms - from Intel CPU to AMD cpu. You know, there are many difficulties to achieve it - like various extensions, instructions and so on.

So far, it was possible to migrate between processors of different family of one vendor only. Now, Red Hat can do it with RHEL and KVM which means Red Hat confirmed the replacement of XEN with KVM definitely. I wrote about it a few months ago here. The whole video story is published at youtube.

I may add that in RHEL there will be a utility called xenner, using which you will be able to run xen paravirtualized kernels as guests on linux hosts, without the xen hypervisor, using kvm instead.

KVM has been able to live migrate between Intel and AMD processors for a long time. It can also migrate 32bit guests between 32bit and 64bit hosts.

The real news here is that now that RedHat have acquired Qumranet we are finally starting to see some marketing.

KVM is a great technology. Hopefully it will gain some mind share with RedHat behind it, as currently it is a bit of a hard sell.
