in the new case we have the same qemu/libvirt version in both nodes 4.2.1Debian 1:4.2-3ubuntu6.7~cloud0
and in this cae its failng for the virtio-blk device not the memroy ballon before the migration starts we see -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ -msg timestamp=on char device redirected to /dev/pts/2 (label charserial0) virtio: bogus descriptor or out of resources 2020-11-20 14:25:39.911+0000: initiating migration on the destination https://zuul.opendev.org/t/openstack/build/d50877ae15db4022b82f4bb1d1d52cea/log/logs/subnode-2/libvirt/qemu/instance-0000001a.txt then on the source we see char device redirected to /dev/pts/1 (label charserial0) 2020-11-20T14:25:40.720757Z qemu-system-x86_64: VQ 0 size 0x80 Guest index 0xb8 inconsistent with Host index 0xe0: delta 0xffd8 2020-11-20T14:25:40.720785Z qemu-system-x86_64: Failed to load virtio-blk:virtio 2020-11-20T14:25:40.720790Z qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk' 2020-11-20T14:25:40.720824Z qemu-system-x86_64: load of migration failed: Operation not permitted when it fails https://zuul.opendev.org/t/openstack/build/d50877ae15db4022b82f4bb1d1d52cea/log/logs/libvirt/qemu/instance-0000001a.txt -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1761798 Title: live migration intermittently fails in CI with "VQ 0 size 0x80 Guest index 0x12c inconsistent with Host index 0x134: delta 0xfff8" Status in OpenStack Compute (nova): Confirmed Status in QEMU: New Bug description: Seen here: http://logs.openstack.org/37/522537/20/check/legacy-tempest-dsvm- multinode-live- migration/8de6e74/logs/subnode-2/libvirt/qemu/instance-00000002.txt.gz 2018-04-05T21:48:38.205752Z qemu-system-x86_64: -chardev pty,id=charserial0,logfile=/dev/fdset/1,logappend=on: char device redirected to /dev/pts/0 (label charserial0) warning: TCG doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5] 2018-04-05T21:48:43.153268Z qemu-system-x86_64: VQ 0 size 0x80 Guest index 0x12c inconsistent with Host index 0x134: delta 0xfff8 2018-04-05T21:48:43.153288Z qemu-system-x86_64: Failed to load virtio-blk:virtio 2018-04-05T21:48:43.153292Z qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk' 2018-04-05T21:48:43.153347Z qemu-system-x86_64: load of migration failed: Operation not permitted 2018-04-05 21:48:43.198+0000: shutting down, reason=crashed And in the n-cpu logs on the other host: http://logs.openstack.org/37/522537/20/check/legacy-tempest-dsvm- multinode-live- migration/8de6e74/logs/screen-n-cpu.txt.gz#_Apr_05_21_48_43_257541 There is a related Red Hat bug: https://bugzilla.redhat.com/show_bug.cgi?id=1450524 The CI job failures are at present using the Pike UCA: ii libvirt-bin 3.6.0-1ubuntu6.2~cloud0 ii qemu-system-x86 1:2.10+dfsg-0ubuntu3.5~cloud0 To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1761798/+subscriptions
