[ovirt-users] ipxe-roms-qemu question

Hi all, in the past we have used customized ipxe (to allow boot over network with 10G cards), now we have finally updated our hypervisors to the latest ipxe-roms-qemu Of course the sum now differs and during live-migration the libvirtd throws this error: Mar  4 11:37:14 hypevisor-01 libvirtd: 2019-03-04 10:37:14.084+0000: 15862: error : qemuMigrationJobCheckStatus:1313 : operation failed: migration out job: unexpectedly failed Mar  4 11:37:15 hypevisor-01 libvirtd: 2019-03-04T10:37:13.941040Z qemu-kvm: Length mismatch: 0000:00:03.0/virtio-net-pci.rom: 0x20000 in != 0x40000: Invalid argument Mar  4 11:37:15 hypevisor-0 libvirtd: 2019-03-04T10:37:13.941090Z qemu-kvm: error while loading state for instance 0x0 of device 'ram' Mar  4 11:37:15 hypevisor-0 libvirtd: 2019-03-04T10:37:13.941530Z qemu-kvm: load of migration failed: Invalid argument is there an easy command we can use to identify what guests are still using the old .rom and must be powercycled ? Thank you in advance
