-Unlike DPDK ring ports, DPDK vhost ports can have arbitrary names:

vhost-user1 type=dpdkvhostuser`
-`ovs-vsctl add-port br0 port123ABC -- set Interface port123ABC
type=dpdkvhost`
+ This action creates a socket located at `/tmp/vhost-user1`,
Although it is implied above, please make it clear that there is a
unique socket for each vhost user port and that unique socket must be
referenced in the quemu command that attaches the particular socket to a
guest's virtual device.
Although it is implied, I think it should be explicit. This confused me
the first time I used vhost-user. Having been accustomed to vhost-cuse I
perhaps foolishly tried to reference the same socket in each guest which
causes qemu to hang.
