So this is a KVM guest running the Xen hypervisor (via -kernel) and a
Dom0 Linux guest (via -initrd)?
Should this work for any Xen architecture or is this x86 specific? Does
the -M machine model matter?
Would it be possible to have some sort of overview document in our
manual for how Xen guests are supported under KVM?
