Hi all,
We are experiencing an issue on 2 proxmox nodes. They are newly installed 2.3.4
servers. One is master and syncing with pfsync to the second one. Sync works
well. Each of these proxmox nodes hosts 2 VMs : a pfsense for firewalling and a
vyos for bgp sessions with our ISP.
We have an OpenVswitch bridge vmbr0 linked to eth4, a 10Gb physical interface.
(Broadcom NetXtreme II, BCM57810).
I have no errors on the physical interface, but on vmbr0 I can see nearly 10%
dropped packets. (on both proxmox nodes)
vmbr0 Link encap:Ethernet HWaddr 00:0e:1e:7c:68:80
inet6 addr: fe80::20e:1eff:fe7c:6880/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:8154568 errors:0 dropped:1136061 overruns:0 frame:0
TX packets:157423 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1
RX bytes:1631993883 (1.5 GiB) TX bytes:120943834 (115.3 MiB)
The VMs are using e1000 drivers. I saw on several topics that switching to
virtIO seems to solve this dropped packets problem. On the other way, CARP VIP
documentation for pfsense advise to use e1000 drivers or CARP may not work.

Am I in a deadlock issue?
What would you advise me to do?
Regards,
