Re: [Xen-devel] Xen + Remus

Well...

Here is the facts:

I start a VM with Windows 2003 installed in DRBD. This DRBD partition is 
the storage from two nodes...
I start remus --no-net Windows-2003-I xen-slave ( yes. xen-slave is 
backup machine)
After 3 minutes, the VM starter on backup side, and the master side, I 
reviece any debug message:
[2010-01-12 15:22:31 4046] INFO (XendDomainInfo:2066) Domain has 
shutdown: name=Windows-2003-I id=2 reason=suspend.
But in backup side I see this message:

2010-01-12 15:17:26 3939] DEBUG (XendCheckpoint:286)

And VM started in backup side without any intervention....!!!!!!!!!

Some idea???

Thanks
