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

File "/usr/lib/xen-unstable/lib/python/xen/util/auxbin.py", line 30, in

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
