[ovs-discuss] Newbie question

[Tyrion Lannister]

Thanks. This worked. Now I cannot create VMs using virt-install or
virt-manager. Is this not supported? With virt-install, I get an error
saying
"Failed to add tap interface to bridge. br0 is not a bridge device"

As per the instructions, I have removed the bridge module and want to use
the ovs. I see the source has this thing called ovsbrcompat, but I am not
necessarily looking to get the linux bridge compatibility.
