- vhost-user reconnect is a new feature added
in dpdk 16.07 and qemu 2.7.
- vhost-user reconnect allows VMs using vhost-user
interfaces to reconnect to the vhost-user backend if
the backend terminates either as a result of a graceful
shutdown or a crash with out requiring the vm to reboot.
- vhost-user reconnect requires qemu to be the vhost-user server
and ovs to be the client.
- dpdk prior to 16.07 only supports qemu client/ dpdk server mode.
- This change extends the ovs mech driver to select the correct qemu
vhost user socket mode based on the available interface types
reported by the agent.
