Proxmox VE 4.2 bridged network issue

[rutopy]

So, we have

# lspci | grep Ethernet
02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

# modinfo e1000e | grep version

Network is setup with bridge. All works, but we have next issue (ping from proxmox machine to any virtual):

Ping throuth bridge has been increases randomly. So, at this time link at network services, that works on virtual machines has been dropped (rdp, voip, etc).


Thanks.

Ok, seems IT IS BUG:

"use VirtIO instead of Intel E1000 as Network Device Model as been applied and the problem seems to be solved."
