[Bug 1050934] Re: VM stops receiving packets on heavy load from virtio network interface briged to a bonded interface on kvm hypervisor

[ITec]

Yes, the switch is 802.3ad enabled.

LACP Group Status says:

System ID       :00:15:77:C1:76:92

Key: 1
Aggregator	Attached Port List
9	9,10
10

"Key" and "SystemID" correspond with "Partner Key" and "Partner Mac
Address" shown in /proc/net/bonding/bond2

I tried the same tests with a container. I had to change
"lxc.network.bridge=brb2" to "lxc.network.link=brb2" to get it work.

The problem did not occur in the container.
Nor does it occur with emulated NICs like e1000 in the virtual machine. But these are much slower than NICs of the type virtio. Does lxc use virtio?
It only occurs with virtio.
