hi.


I'm sorry can not reply to the original letter.


openvswitch and brctl can run normal together in RHEL6.3.


error message:

>ProcessExecutionError: Unexpected error while running command.
>Command: sudo nova-rootwrap /etc/nova/rootwrap.conf brctl addbr
>qbr2218b8c4-7d

Solution:


1.openvswitch process running in backend

2.modprobe brcompat_mod

3.ovs-brcompatd --pidfile --log-file --detach

4.ovs-vsctl add-br br-int...add-port...（if you have done then not need redo）

5.login dashboard and launch instance.
6.check instance status,it is ok.

NOTE:
1.the process ovs-brcompatd will be shutdown when run "service openvswitch stop"，then pls startup it by manual.
2.# brctl show
