Hi Maxime/Chenbo
We are using lib/librte_vhost to implement our virtio-backend devices.
Does DPDK vhost-user support VIRTIO_F_NOTIFY_ON_EMPTY, the legacy interface
reserved feature bit? (The 6.3 section in
https://stefanha.github.io/virtio/vhost-user-slave.html)
I'd see it set in VIRTIO_NET_SUPPORTED_FEATURES in vhost.h. So, will it
cause an exception if we migrate the VM which uses vhost_net and enable
VIRTIO_F_NOTIFY_ON_EMPTY?
Look forward to hearing from you.
Thanks
Ping Yang
