Hi Jesse,
I followed the steps in INSTALL.usespace to create bridge br0 and there were
no error messages. How do I check if the bridge br0 is created? I tried
"brctl show" but i didn't see bridge br0.
I am running Xen3.3 with Debian kernel 2.6.26-2-xen-686 as dom0 and ubuntu
9.04 as domUs. I have a linux bridge "eth0" which is bounded to interfaces
peth0 and vif1.0.
e...@ettm:~$ brctl show
bridge name bridge id STP enabled interfaces
eth0 8000.00256449d794 no peth0
vif1.0
pan0 8000.000000000000 no
I want to create a bridge br0 using open vswitch with interfaces peth0 and
vif1.0 and replace the linux bridge eth0. I am not sure how to go about
doing that using open vswitch. I would appreciate any help I can get.
Thanks
Hardeep
