Public bug reported: This bug is the same as [1], but that bug wasn't solved completely. It also fails occasionally during REVERT_RESIZE operation.
The more detail is: Description =========== This is all only when Neutron is using OVS with hybrid plugging. When reverting a resized instance from dest host back to its original source host(source host is different from dest host), Nova will timeout waiting for the vif-plugged external event, and never finish the revert. This happens because Nova wait the vif-plugged external event which the vif status is inactive from the network info[2]. But the network_info is too old, although the vif status is inactive in network_info, actually it maybe active. If the vif status is active actually, Nova will timeout. Steps to reproduce ================== 1. Resize an instance 2. When it's in VERIFY_RESIZE, revert it Expected result =============== Instance reverts correctly. Actual result ============= Instance goes to ERROR. Environment =========== OVS with hybrid plug. The Nova release is Rocky. And affected the release after the Rocky.
