4817165fc5938a553fafa1a69c6086f9ebe311af, when reverting a\nresized instance back to the source host, the libvirt driver waits for\nvif-plugged events when spawning the instance. When called from\nfinish_revert_resize() in the source compute manager, libvirt\u0027s\nfinish_revert_migration() does not pass vifs_already_plugged to\n_create_domain_and_network(), making the latter use the default False\nvalue.\n\nWhen the source compute manager calls\nnetwork_api.migrate_instance_finish() in finish_revert_resize(), this\nupdates the port binding back to the source host. If Neutron is\nconfigured to use OVS hybrid plug, it will send the vif-plugged event\nimmediately after completing this request. This happens before the\nvirt driver\u0027s finish_revert_migration() method is called. This causes\nthe wait in the libvirt driver to time out because the event is\nreceived before Nova starts waiting for it.\n\nThe neutron ovs l2 agent sends vif-plugged events when two conditions\nare met. First the port must be bound to the host managed by the\nl2 agent and second, the agent must have completed configuring the\nport on ovs. This involves assigning the port a local VLAN for tenant\nisolation, applying security group rules if required and applying\nQoS policies or other agent extensions like service function chaining.\n\nDuring the boot process, we bind the port first to the host\nthen plug the interface into ovs which triggers the l2 agent to\nconfigure it resulting in the emission of the vif-plugged event.\nIn the revert case, as noted above, since the vif is already plugged\non the source node when hybrid-plug is used, binding the port to the\nsource node fulfils the second condition to send the vif-plugged event.\n\nEvents sent immediately after port binding update are hereafter known\nas \"bind-time\" events. For ports that do not use OVS hybrid plug,\nNeutron will continue to send vif-plugged events only when Nova\nactually plugs the VIF. These types of events are hereafter known as\n\"plug-time\" events. OVS hybrid plug is a per agent setting, so for\na particular host, bind-time events are an all-or-nothing thing for the\novs backend: either all VIF_TYPE\u003dovs ports have them, or no ovs ports\nhave them. In general, a host will only have one network backend.\nThe only exception to this is SR-IOV. SR-IOV is commonly deployed on\nthe same host as other network backends such as OVS or linuxbridge.\nSR-IOV ports with VNIC_TYPE\u003ddirect-physical will always have only\nbind-time events. If an instance mixes OVS ports with hybrid-plug\u003dFalse\nwith direct physical ports, it will have both kinds of events.\n\nFor same host resize reverts we do not update the binding host as the\nhost does not change, as such for same host resize we do not receive\nbind time events. For same host revert we therefore do not wait for\nbind time events in the compute manager.\n\nThis patch adds functions to the NetworkInfo model that return what\nkinds of events each VIF has. These are then used in the migration\nrevert logic to decide when to wait for external events: in the\ncompute manager, when binding the port, for bind-time events,\nand/or in libvirt, when plugging the VIFs, for plug-time events.\n\n(cherry picked from commit 7a7a223602ca5aa0aca8f65a6ab143f1d8f8ec1b)\nConflicts in nova/tests/unit/objects/test_migration.py due to\n1cf3da87027d87251920c2df665b850abb31178e\u0027s addition of\ntest_obj_make_compatible() and test_get_by_uuid().\n\n(cherry picked from commit e34d0fee85b486ac282ffd6d155666e62890b2bf)\n\nCloses-bug: #1832028\nCloses-Bug: #1833902\nCo-Authored-By: Sean Mooney \u003cwork@seanmooney.info\u003e\nChange-Id: I51673e58fc8d5f051df911630f6d7a928d123a5b\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/7e22e19653a5fc67ceab651f221fca0325f26cdb"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/7e22e19653a5fc67ceab651f221fca0325f26cdb"}]},"branch":"refs/heads/stable/rocky"},"d9892abd2f096c05a2885a4902128941a24f5670":{"kind":"REWORK","_number":2,"created":"2019-07-12 23:24:00.000000000","uploader":{"_account_id":8864,"name":"Artom Lifshitz","email":"notartom@gmail.com","username":"artom"},"ref":"refs/changes/48/670648/2","fetch":{"anonymous http":{"url":"https://review.opendev.org/openstack/nova","ref":"refs/changes/48/670648/2","commands":{"Checkout":"git fetch https://review.opendev.org/openstack/nova refs/changes/48/670648/2 \u0026\u0026 git checkout FETCH_HEAD","Cherry Pick":"git fetch https://review.opendev.org/openstack/nova refs/changes/48/670648/2 \u0026\u0026 git cherry-pick FETCH_HEAD","Format Patch":"git fetch https://review.opendev.org/openstack/nova refs/changes/48/670648/2 \u0026\u0026 git format-patch -1 --stdout FETCH_HEAD","Pull":"git pull https://review.opendev.org/openstack/nova refs/changes/48/670648/2"}}},"commit":{"parents":[{"commit":"b8a2323c64c833128fad93d9db6faf662d63211e","subject":"Merge \"Ignore hw_vif_type for direct, direct-physical vNIC types\" into stable/rocky","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/b8a2323c64c833128fad93d9db6faf662d63211e"}]}],"author":{"name":"Artom Lifshitz","email":"alifshit@redhat.com","date":"2019-03-20 14:38:12.000000000","tz":-240},"committer":{"name":"Artom Lifshitz","email":"alifshit@redhat.com","date":"2019-07-12 23:19:58.000000000","tz":-240},"subject":"Revert resize: wait for events according to hybrid plug","message":"Revert resize: wait for events according to hybrid plug\n\nSince 4817165fc5938a553fafa1a69c6086f9ebe311af, when reverting a\nresized instance back to the source host, the libvirt driver waits for\nvif-plugged events when spawning the instance.
