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/liveMig... 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. -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
