[Xen-devel] xen.lowlevel.xu.PortError: Failed to map domain control interface

[Nils Toedtmann <mail@xxxxxxxxxxxxxxxxxx>]

Dear list,

after running several days with some domUs, i did a

  service xend stop
  service xend start

The second failed, /var/log/xend-debug.log said

  xen.lowlevel.xu.PortError: Failed to map domain control interface

Complete xend-debug.log is here:

  <http://nils.toedtmann.net/stuff/virtualization/xend-debug.log>

Two events happened before and may have something to with this oops:
python was updated (FC3 2.3.4-11 ==> 2.3.4-13.1), and a domU i rebooted
got stuck (it shut down, but did not boot again).

All other domains were still runnning and accessable via net. A reboot
of the host solved the problem.

It was xen-2.0-testing, probably from 2005/03/15, dom0=2.6.11.3,
domU=2.6.11.4 (patched with a later xen-2.0-testing)

What went wrong?

/nils.
