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
