KVM is a great replacement for Xen. It's much easier to use for a start -- no more rebooting into a completely separate kernel^W hypervisor. As long as you have the virtio drivers in the guest, which is the default for all new Linux distros, performance is roughly the same. > Also I am missing some howtos for migration to KVM/xenner. Install a recent Linux kernel in the guest, adjust the configuration file[1], and reboot. You only need Xenner if you want to run the Xen PV guest unchanged (ie. without installing a new guest kernel). Rich.
