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 ...
