After Livemigration from Windows2008 Server, i musst reset the VM

[fireon]

Hi,

when i to an livemigration from an Windows 2008 Server r2, after the migration is finish i can do something in RDP and after a few minutes i can only reset the VM. The Image is on an NFSshara. I testet the migration between two identical HP Servers. And once i migrate from an opteron to an xeon. Every time the same.

Scsi controller Type: Isi Default
Disktyp qcow2
1 Socket 4 Cores
4GB RAM
Network Virtio

What is going wrong? With Linux this works normaly. I've not testet this with Windows7 or 8.

Regards
Fireon
