Hi Charles,

We use an Ethernet cable to connect between the hosts through 10G port.

We want to use the guest VM's hosted on different hosts 10G network. oVirt
already supports SR-IOV. So we should guest 10G speed for our VM's.

In KVM we can create a second bridge and add the 10G interface to the
bridge would do the trick.

But in oVirt how do we do this? We want to use our OVs network, which was
created using OVN Provider.
