Migrating from Xen to KVM

Posted by Jamie Neil on 22 May 2008

We've been using Xen for server virtualisation for a few years now, and it's generally worked very well (the only real problem that I've had is with kernel upgrades).  However some of the new hardware we've been buying (like Dell R200 servers) requires a kernel > 2.6.18, which is the last kernel version that Xen support "officially". It's possible to get later kernels with Xen support compiled in from other vendors, but at the moment it looks like running a dom0 is far from straightforward. So after wasting the best  part of a day trying to get Xen working on a 2.6.24 kernel, I gave up and decided to take a look at KVM.
