We just upgraded an OpenStack compute from 16.04.4 to 16.04.5 and live migration is broken for VMs running on a 16.04.4 host to a 16.04.5 host.
We see these error messages in nova-compute.log on a 16.04.4 host: 2019-01-08 07:43:56.117 100671 ERROR nova.virt.libvirt.driver [-] [instance: 3ac1a38d-b3fa-4d02-a94e-b71136bcf07f] Migration operation has aborted 2019-01-08 07:43:56.230 100671 INFO nova.compute.manager [-] [instance: 3ac1a38d-b3fa-4d02-a94e-b71136bcf07f] Swapping old allocation on 61c651ad-62e7-4137-ab35-924cd204ebb9 held by migration 1368009a-67aa-4574-9ed5-4fb7a513d06e for instance 2019-01-08 07:43:56.311 100671 ERROR nova.virt.libvirt.driver [-] [instance: 3ac1a38d-b3fa-4d02-a94e-b71136bcf07f] Live Migration failure: internal error: qemu unexpectedly closed the monitor : 2019-01-08T07:43:55.658574Z qemu-system-x86_64: -drive file=rbd:volumes_hdd/volume-08bf868c-23a9-43c5-b00f-91e3dc7e4220:id=cinder:auth_supported=cephx\;none:mon_host=172.16.0.144\:6789\;172 .16.0.145\:6789\;172.16.0.149\:6789,file.password-secret=virtio-disk0-secret0,format=raw,if=none,id=drive-virtio-disk0,serial=08bf868c-23a9-43c5-b00f-91e3dc7e4220,cache=writeback,discard=unma p: 'serial' is deprecated, please use the corresponding option of '-device' instead 2019-01-08T07:43:55.951328Z qemu-system-x86_64: Length mismatch: 0000:00:03.0/virtio-net-pci.rom: 0x40000 in != 0x80000: Invalid argument 2019-01-08T07:43:55.951350Z qemu-system-x86_64: error while loading state for instance 0x0 of device 'ram' 2019-01-08T07:43:55.951499Z qemu-system-x86_64: load of migration failed: Invalid argument: libvirtError: internal error: qemu unexpectedly closed the monitor: 2019-01-08T07:43:55.658574Z qem u-system-x86_64: -drive file=rbd:volumes_hdd/volume-08bf868c-23a9-43c5-b00f-91e3dc7e4220:id=cinder:auth_supported=cephx\;none:mon_host=172.16.0.144\:6789\;172.16.0.145\:6789\;172.16.0.149\:67 89,file.password-secret=virtio-disk0-secret0,format=raw,if=none,id=drive-virtio-disk0,serial=08bf868c-23a9-43c5-b00f-91e3dc7e4220,cache=writeback,discard=unmap: 'serial' is deprecated, please use the corresponding option of '-device' instead During the update the package ipxe-qemu was installed in version 1.0.0+git-20180124.fbe8c52d-0ubuntu2.1~cloud0. As suggested in comment #1 downgrading to 1.0.0+git-20150424.a25a16d- 1ubuntu1.2 fixed the problem for us. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713490 Title: error migrating blocked on virtio-net-pci.rom To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ipxe/+bug/1713490/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
