Snapshot > lost network connection ...

[bue]

Hi,

i have a problem with the snapshot function.

Everytime when i create a snapshot, the network connection from the vm (only the one) is broken and I can't ping the vm!

Is that normal?

you should give more info about your vm and snapshot storage, at least...

Okay

VMs are located on the Proxmox Host

Proxmox Host:
Memory: 32 GB
HDD: HD2.5" SAS2 600GB HGST HUC109060CSS600 /10k### (8x on Raid10)
Raidcard: LSI MegaRAID 9271-8I PCIe 3.0 SAS 8 HDD sgl. with backup battery
CPU: CPU Intel XEON E5-2650/8x 2.0 GHz/8 GT/s/20 MB (2x)
Network: 4 x 1 Gbit (at the moment, every machine has one networkcard ..)

Snapshot Storage:
Nas
Hdd: 1 TB
Network: 2 x 1 Gbit on bonding

But we have the same problem also when the snapshots are saved on the proxmox host :S

Every VM:
Hard Disk: 300 GB (VirtIO)
Network: 1 x 1 Gbit (VirtIO)
1 Socket, 4 Cores
OS: Windows Server 2008 R2 with MySQL and so on ..
