[PVE-User] Debian 7 guest losing network

[Eneko Lacunza]

Hi,

Just for the record, I tried with latest backport kernel, but we're 
seeing the problem yet.

Today it has lost network 3 times (the last one with 3.16 bpo kernel), 
this is a change since the previous about-1-week frequency...

Cheers
Eneko
