Hi, thi is really strange, I'm running around 1000 debian vms in production,
wheezy with 3.16 kernel or jessie with 3.16, and I never had packets drop like this. ----- Mail original ----- De: "Eneko Lacunza" <[email protected]> À: "proxmoxve" <[email protected]> Envoyé: Jeudi 1 Octobre 2015 17:33:38 Objet: Re: [PVE-User] Debian 7 guest losing network 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...
