Is there a introducing comparison of the different network blockdevice
techniques like NBD/ENBD/GNBD, DRDB or iSCSI? You seem to prefer iSCSI

Is network blockdevice sharing (that's meant with "multipath", right?)
necessary for "xm migrate"?

As the ethernet checksum is (afaik) over the hole frame it should be ok
as long as GNDB is done within a L2 segment, correct?

/nils.
