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

Hi,
Not sure it's related but
I remember some network latency problems with kernel 3.2 from wheezy and virtio
nics in the past.
Using kernel 3.16 from backports fixed the problem.

Objet: [PVE-User] Debian 7 guest losing network
Hi all,
I have a PVE 3.4 node with pve kernel 2.6.32-39 (details below).
A quite busy Samba server VM is losing network conectivity about every
week since 27th August.
This VM can't ping other network elements, and one can't access the
Samba in the VM nor ping it when this happens.
VM is a security-updated Debian 7. Last apt-get upgrade in the VM before
first lost network was on 19th August.
Last Proxmox update was on 15th June, so I don't really think this is a
Proxmox related issue - but I'm sure there are lot's of Debian 7 VMs out
there. Is anyone having this problem? Any idea?
I tried both e1000 and virtio network adapters, but VM continues to lose
network. I do have other 2 Debian 7 hosts in the cluster (one in the
same host), but they are not so busy (and haven't lost network for now).
