FAQ is updated to reflect the latest DPDK for each OVS branch.
David has reported a crash for virtio_user devices with 20.11.3 [1]. I
ran a quick test of adding a virtio_user port to OVS and there was no
crash, but maybe it was not a full test or I was lucky.
After talking to David, I reproduced with:
ovs-vsctl add-port br0 virtio_user0 -- set Interface virtio_user0
type=dpdk
options:dpdk-devargs=net_virtio_user0,iface=tap0,path=/dev/vhost-net,queues=3
You'd need to check if there are fixes impacting OVS in 20.11.3 that
make it better to take now and document this known issue. Otherwise,
probably better to wait until 20.11.4 with the fix for this.
Can you check if it is ok to use 20.11.3 with this known issue?
