xend.log entry from today:
[2012-11-14 11:27:24 2879] DEBUG (XendDomainInfo:1477) Setting memory 
target of domain ldap (2) to 512 MiB.
messages errors:
Nov 14 11:29:06 localhost kernel: : [37380.393789] XENBUS error -22 
while reading message
xenfs is not mounted on dom0 - could it be the reason of this issues?

Any thoughts?
