Re: [Xen-users] XEN 4.3.0 Complete Crash on Kernel vmlinuz-3.2.0-4-amd64

[Maik Brauer <maik.brauer@xxxxxxxxxxxxxxx>]

Hi Robert,

many Thanks for your last post. I have got the XEN System up and running now 
with Kernel 3.10.9

BUT, there is still one issue, during reboot, when DomU's are running.
After giving a reboot command the system tries to shutdown, but it does not 
save any DomU in the predefined /var/lib/xen/save folder.
Only a Hardware reset will bring the Dom0 back to a running state.

In case there is no DomU running (no save/suspend necessary) the reboot will be 
successful.
Any thoughts?
Thanks.

Cheers,
Maik
