[Xen-users] xend OSError: [Errno 2] No such file or directory

[Martin Kraus <lists_mk@xxxxxxxxxxx>]

Hi,
  I've moved a domU (copied configuration and filesystem) from machine with
debian xen hypervisor and utils 3.0.3 to a machine with debian
xen-hyperviso-unstable (3.3+hg17961) with utils 3.3 and the domU either
fails with with kernel panic, because it cannot mount root filesystem or
freezes before the kernel boots or I get something about

OSError: [Errno 2] No such file or directory

which I can't simulate right now. I've noticed that xend starts, but during
it's start it says:

Starting XEN control daemon: xendTraceback (most recent call last):
  File "/usr/lib/xen-unstable/bin/xend", line 146, in <module>
    sys.exit(main())
  File "/usr/lib/xen-unstable/bin/xend", line 123, in main
    start_blktapctrl()
  File "/usr/lib/xen-unstable/bin/xend", line 107, in start_blktapctrl
    execute('blktapctrl')
  File "/usr/lib/xen-unstable/lib/python/xen/util/auxbin.py", line 30, in
execute
    os.execv(exepath, a)
OSError: [Errno 2] No such file or directory

which I guess is related.

this is /var/log/xen/xend.log:

the configuration and kernel version is same on both machines. is it something
wrong with this version of xen, or am I being just blind to the obvious?

thanks for help
