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.

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.

virt-p2v converts physical machines to virtual machines. Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.
