Now Linode (one of the largest Xen sites) is moving to KVM, they list the above as benefits of KVM which surprises me.
For anyone who has Xen instances with Linode, note that they have a migration option that you can invoke, although they make it clear that all instances will switch to KVM eventually. If you're running your own kernel rather than theirs, the migration to Xen also entails a welcome upgrade to Grub 2 - now I no longer have to deal with Grub 1 anywhere. I have run kvm on a laptop, but not recently, and I didn't undertake performance testing. As with other virtualizzation tools, there's an advantage to running paravirtualization, as is the default for Linux guests; full virtualization is available for running BSD or something else as your guest system.
