[Xen-users] Problem: xend.log says "VM restarting too fast. Refusing to restart to avoid loops"

[Andrea Monti <ilsuonogiallo@xxxxxxxxx>]

Hi all,

one of my servers crashed last sunday just right after a startup and I need to understand what was going on.

I am running Windows 2008 R2 Standard Edition on Oracle VM 3.1 - Xen 4.1.2-OVM

On sunday a scheduled task shutted down cleanly the vm.

the shutdown started at Sun Jun 16 10:00:33  and it ended at 2013-06-16 10:00:46.938.

xend.log says:

[2013-06-16 10:00:45 7228] INFO (XendDomainInfo:2148) Domain has shutdown: name=0004fb00000600008f562ccf5ed488f8 id=6 reason=poweroff.

So far, so good

The same virtual machine has been started on Sun Jun 16 10:01:55 . xend.logs says
[2013-06-16 10:01:56 7228] DEBUG (XendDomainInfo:106) XendDomainInfo.create(['vm', ['name', '0004fb00000600008f562ccf5ed488f8'], ['memory', 1536], ['maxmem', 1536], ...

once again so far so good

After less than one minute xend.log says

[2013-06-16 10:02:54 7228] WARNING (XendDomainInfo:2131) Domain has crashed: name=0004fb00000600008f562ccf5ed488f8 id=7.

WHAT !?!?!

What does "VM restarting too fast" mean?

Thanks for every answer

Regards

Andrea
