- 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.

features:
|
|
- vhost-user reconnect is a mechanism which allows
|
|
a vhost-user frontend to reconnect to a vhost-user
|
|
backend in the event the backend terminates.
|
|
This enable a VM utilising a vhost-user interface
|
|
to reconnect automatically to the backend e.g.
|
|
a vSwitch without requiring the VM to reboot.
|
|
In this release, support was added to the neutron
|
|
Open vSwitch agent and ml2 driver for vhost-user
|
|
reconnect.
|
|
other:
|
|
- 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 without requiring the VM to reboot.
|
|
- vhost-user reconnect requires dpdk 16.07 and qemu 2.7
|
|
and ovs 2.6 to function. if an older qemu is used,
|
|
reconnect will not be available but vhost-user will
|
|
still function.
