I guess this may be a bug and should be reported. I`d try sending a
report to the xen-users list about the live migration issue you are
currently experiencing. Do note that, VM virtual storage needs to be
agile, eg in an NFS/ISCSI/FC setup seen by both hosts in the same way.
Also, if the VM isn't paravirtualized, it will not migrate.

This might be a bug in blktap / tapdisk activation, run the question
thru the xen-users list and if not much help, send the  question to
the xen-devel list. If you have a serial port, it may be helpful to
log the serial output somewhere and send it to the xen-devel list.

xl is new a new and lightweight toolstack. Give it sometime and don't
despair ;-)

XCP is an opensource toolstack which is far better than xend. XS is
opensource and has a free edition. For some uses, it might suit your

The positive points at the moment may not be very noticeable or
clearly known yet, but xend is only useful for home setups. It's not
made to scale.
