Are you running as root? 

One change in the past while is the use of unix domain sockets rather 
than [loopback] network sockets as the basic comms mechanism used by 
the tools, which has a (desired!) side-effect of adding basic access
control to the xm <-> xend interface.

If this is not it, can you please try either/or: 
 
  - looking at the log files /var/log/xend.log /var/log/xend-debug.log
    to see if anything jumps out at you
  - running "strace xm <foo>" to see if anything's up at that side. 

cheers,

S.
