   Hi all,

   I Installed Xen 3.4.2 from source on Ubuntu 9.10 using the pv-ops dom0 kernel from Jeremy' git tree. Now the system boots up but trying "sudo xend start" raises this issue:

ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
Traceback (most recent call last):
  File "/usr/sbin/xend", line 36, in <module>
    from xen.xend.server import SrvDaemon
  File "/usr/local/lib/python2.6/dist-packages/xen/xend/server/SrvDaemon.py", line 26, in <module>
    import relocate
  File "/usr/local/lib/python2.6/dist-packages/xen/xend/server/relocate.py", line 28, in <module>
    from xen.xend import XendDomain
  File "/usr/local/lib/python2.6/dist-packages/xen/xend/XendDomain.py", line 35, in <module>
    from xen.xend import XendOptions, XendCheckpoint, XendDomainInfo
  File "/usr/local/lib/python2.6/dist-packages/xen/xend/XendCheckpoint.py", line 20, in <module>
    from xen.xend import balloon, sxp, image
  File "/usr/local/lib/python2.6/dist-packages/xen/xend/image.py", line 46, in <module>
    xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

Can you please help me to know what is wrong with my installation?

$ uname -a (returns)
Linux afshar-vm-ubuntu 2.6.31.6 #1 SMP Wed Nov 25 03:13:22 EST 2009 i686 GNU/Linux

$ sudo find / -name xend (returns)
/etc/init.d/xend
/usr/sbin/xend
/usr/local/lib/python2.6/dist-packages/xen/xend

Thanks,
--Afshar;
