Hello,

I successfully attached VF to a VM on a single PF nic following https://access.redhat.com/articles/3215851.

I want the vm with VF to be migratable, but the nic hotplug/replug is too long. So I tested the mode 1 bonding (active-backup) with a virtio nic following this

https://www.ovirt.org/develop/release-management/features/network/liveMigrationSupportForSRIOV.html

On a single PF, the resilience tests with migration are correct with 1 or 2 second downtime.

But now I want to do the same on a typical host with LACP PF:

Considering vlan13, I must bond a virtio nic on a brv13/brv13 profile with SR-IOV/brv13 profile as the primary interface.

Everything work when the primary interface is brv13/brv13 profile (work as a traditionnal bridge config), but not when changing on the SR-IOV/brv13 profile.

I know in this case that the SR-IOV profile is connected to a LACP interface, but does it mean that I have to configure the VF vnic in the VM to be part of the LACP(bond1) as a single member and in that case to do active-backup bond0 with two members bond1 and brv13 nic?

Hope to be clear enough.

Thanks for your help.
