Virtual router, ovs, virtio, low speed.

[ibs0d]

Hi, i use virtual router freebsd 9.2 (R1) with virtio net on proxmox3.4 (S1) with last updates from public repo, network open-vswitch (2.3.1-1) based, bonding six links (balance-tcp). When u14.04 guest (G1) use virtio network adapter, i have very low speed connections trough R1, but good speed connection without routing. If G1 use e1000, then speed good with\without routing.
If G1 on another pve server then virtio works good with\without routing.
Thx.
I redy for question.
