[PVE-User] Continued network loss with virtio Windows and Linux

[Eneko Lacunza]

Hi all,

Just for your information, this ws2012 host has continued to loss 
network connectivity. We have switched to e1000 emulation, to try to 
keep it working.

Also, yesterday in another unrelated cluster, this problem happened 
twice with a Debian wheezy VM. We switched to e1000 emulation too, and 
it has kept working well since then.

So I think there's some kind of bug in latest qemu and network virtio in 
Proxmox. I didn't try virtio .94 and .100 drivers in the Windows host 
(found the problem in the Debian VM before trying that); also, they're 
not marked as stable yet.

I'll report back if we see the same problems with e1000 network.

Cheers
Eneko
