  Oke, so what would be the best way to install for example an ubuntu hvm
  guest with a nfs_root filesystem on a RHEL 5 Xen system?

  Most docs are about guest images on a local filesystem, but isn't it
  reasonable to put your guests disk on a SAN-system? And doesn't give
  NFS you additional integrity in cases of system (guest or dom0) crashes
  (compared to for example iSCSI) ?

  BTW: does anyone have pointers to docs about performance considerations
       about hvm (VTx) versus paravirtualisation guests?
