[PVE-User] Debian 7 guest losing network

[Eneko Lacunza]

Hi,

I do have some tens too, without problem except this one. I have moved 
the VM to another physical server in the cluster in case there's some 
kind of problem with the physical server or switch port (there are 
another 2 VMs in that original proxmox node, but who knows...).

Evening and night have been good; I'll keep the list up-to-date on this 
issue.
