Just curious. What performance problems keep you from running SD in a 
domU? I have been experimenting with running SD in a PV domU, but 
haven't decided if it makes sense. Not for performance reasons, but 
because I have the daemons on a 2-node cluster using heartbeat for 
failover. For Dir it works great. For SD, there are issues. SD auto 
fails over and maintains the same IP, etc. The primary issue is that 
failover still causes a running backup job to fail because the SD-FD TCP 
session is broken and the daemons don't attempt to reconnect. Also, 
after failing because the TCP session is broken, there is no way 
currently to re-run failed jobs. I expect future versions of Bacula will 
address those two issues, and Xen 3.4 brings virtual SCSI and SATA 
devices to domUs. It will be very convenient to run SD in a domU, even 
given the problem that the backup device(s) can only be attached to one 
dom0 at a time and may have to be manually moved.
