Description of problem: Observed in NFV OVN-DPDK HCI setup. When attempting to live migrate an instance from source compute to destination compute using shared block storage, the migration is failing and the following error is logged: nova-compute.log.1:2021-06-02 11:12:56.332 7 ERROR nova.virt.libvirt.driver [-] [instance: 771c4317-2586-4dcd-9c35-99625d6d3934] Live Migration failure: argument unsupported: post-copy is not supported with tunnelled migration: libvirt.libvirtError: argument unsupported: post-copy is not supported with tunnelled migration nova-compute.log.1:2021-06-02 11:12:56.333 7 DEBUG nova.virt.libvirt.driver [-] [instance: 771c4317-2586-4dcd-9c35-99625d6d3934] Migration operation thread notification thread_finished /usr/lib/python3.6/site-packages/nova/virt/libvirt/driver.py:9316 nova-compute.log.1:2021-06-02 11:12:56.626 7 DEBUG nova.virt.libvirt.migration [-] [instance: 771c4317-2586-4dcd-9c35-99625d6d3934] VM running on src, migration failed _log /usr/lib/python3.6/site-packages/nova/virt/libvirt/migration.py:419 nova-compute.log.1:2021-06-02 11:12:56.626 7 DEBUG nova.virt.libvirt.driver [-] [instance: 771c4317-2586-4dcd-9c35-99625d6d3934] Fixed incorrect job type to be 4 _live_migration_monitor /usr/lib/python3.6/site-packages/nova/virt/libvirt/driver.py:9130 nova-compute.log.1:2021-06-02 11:12:56.627 7 ERROR nova.virt.libvirt.driver [-] [instance: 771c4317-2586-4dcd-9c35-99625d6d3934] Migration operation has aborted Version-Release number of selected component (if applicable): Compose: RHOS-16.2-RHEL-8-20210525.n.0 libvirt-bash-completion-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-nwfilter-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-disk-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-logical-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-client-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-config-nwfilter-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libcephfs2-14.2.11-147.el8cp.x86_64 libvirt-libs-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-core-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-nodedev-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-secret-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-gluster-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-iscsi-direct-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 openstack-nova-common-20.6.1-2.20210510134812.10df176.el8ost.2.noarch libvirt-daemon-driver-storage-mpath-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-scsi-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-interface-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-kvm-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 python3-libvirt-7.0.0-1.module+el8.4.0+9469+2eaf72bc.x86_64 openstack-nova-migration-20.6.1-2.20210510134812.10df176.el8ost.2.noarch libvirt-admin-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 ceph-common-14.2.11-147.el8cp.x86_64 python3-ceph-argparse-14.2.11-147.el8cp.x86_64 python3-cephfs-14.2.11-147.el8cp.x86_64 python3-novaclient-15.1.1-2.20201217050840.79959ab.el8ost.1.noarch libvirt-daemon-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-qemu-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-storage-iscsi-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 python3-nova-20.6.1-2.20210510134812.10df176.el8ost.2.noarch libvirt-daemon-driver-storage-rbd-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 libvirt-daemon-driver-network-7.0.0-14.module+el8.4.0+10886+79296686.x86_64 openstack-nova-compute-20.6.1-2.20210510134812.10df176.el8ost.2.noarch How reproducible: 100% of the attempts Steps to Reproduce: 1.
