Public bug reported: After changing the MTU of an OpenStack network, attempting to live-migrate an existing instance fails with e.g.: ERROR nova.virt.libvirt.driver [-] [instance: f3807b12-fa7e-4da8-a688-c5507fb66891] Live Migration failure: unsupported configuration: Target network card MTU 9000 does not match source 1500: libvirt.libvirtError: unsupported configuration: Target network card MTU 9000 does not match source 1500
Indeed, the MTU should not change as per: https://bugzilla.redhat.com/show_bug.cgi?id=1623157 However, it should be the case that libvirt live-migration code should retain the MTU specified in the source domain. If we do that, live- migration still works. ** Affects: nova Importance: Undecided Assignee: Tyler Stachecki (tstachecki) Status: New ** Changed in: nova Assignee: (unassigned) => Tyler Stachecki (tstachecki) -- You received this bug notification because you are a member of Yahoo!
