In addition to Dan's answer, I'm looking into this area too.

There is no easy way to do it at the moment, but currently a virtual
machine image is more likely to work if it's fully virtualized,
ie. uses no virtio or other PV drivers.  Sadly such a virtual machine
will also be much slower.

You can get the guest boot from almost anything with a few simple rules.

First make sure you don't use device names in /etc/fstab. Mount by label/uuid or use lvm, so the guest can find the root filesystem no matter where it lives (ide/scsi/virtio/...). The default fedora partitioning scheme (lvm) should work fine.

Second make sure the initrd loads the drivers needed. You can stick a list into /etc/sysconfig/mkinitrd (MODULES="..."). There isn't that much possible storage hardware one can find in a virtual machine (ide, a few (3?) scsi adapters, virtio, xenbus), so simply loading all possible drivers doesn't waste that much memory ...
