[Xen-users] VM does not reboot

Hello,
yesterday a coworker had to reboot one VM, the Vm did shutdown but
never came back up.
We are USing CentOS 5.1 and XEN xen-3.0-x86_64.

What can be the reason of this behavior?

Here ist the part of the logfile:

[Xen-users] xmclone closes the shell were it runs from

hi everybody,

when I run the xmclone script it exit and closing the shell it´s invoked 
from. I cannot see anything and no log entries seems to be made. When 
redirecting the output to a file it shows the help (since i did not add 
any options) and the last line says exit 1.

Any idea´s on how the debug this any further. without log entries it''s 
hard to understand whats happening

setup
dom0: opensuse 11.0 64bit
xen 3.2.1
xmclone: 0.4.3



best regards,

Isidoros.
