Hi,
I've got an issue about a Windows 2008r2 Server with PVE 6.x :

Here is the configuration of the involved VM for the issue:

virtio8: local-lvm:vm-100-disk-7,cache=writeback,size=280G
Here is the description of the issue:
The guest OS is : Windows SBS 2008r2 (2011)
During the backup (snapshot mode with guest agent installed because we need to keep the VM alive because there are connections from many countries around the world 24/7), the VM becomes unresponsive.
The BACKUP system is on a Synology shared with NFS (mount point is /mnt/pve/NAS/pegasus), connection 1 Gbe (will be updated soon with a 10gbe NIC).
We understand that the backup slow speed is relative of the speed of the NIC.
The problem is when the backup is finished, the VM stays unresponsive. All connections from computers (RDP, Authentication, File-sharing, or anything else) are not working.
When trying to open a session from the console in Proxmox GUI, the prompt works but the server hangs with "opening Desktop".
Nothing works anymore. The only available option left is to STOP the VM and start it again (HARD RESET).
We tried many things:

We tried many things:

- Update all the Virtio Drivers in the guest OS (including virtstor)
- Change SCSI single for the drives to Virtio Block
- Remove C: from the backup in case of a lock problem
