[Bug 1856925] [NEW] Nova compute service exception that performs cold migration virtual machine card in resize state.

 

Public bug reported:

Description:  
 In the case of a nova-compute service exception, such as down, the instance gets stuck in the resize state during cold migration and cannot perform evacuation.The command request for nova API is also issued, server_status and Task State have been changed, but compute cannot receive the request, resulting in the server State remaining in the resize State. When nova-compute is restarted, the server State becomes ERROR.It is recommended to add validation to prevent instances from entering inoperable states.
  This can also happen with commands such as stop/rebuild/reboot.
Environment:
1. openstack-Q;nova -version:9.1.1

2. hypervisor: Libvirt + KVM

3. One control node, two compute nodes.

** Affects: nova
     Importance: Undecided
