[Yahoo-eng-team] [Bug 1942766] [NEW] After the detach volume timeout, the disk is lost after soft reboot

2021-09-06 Thread wlfightup 
Public bug reported:

Description
==
When the detach disk timeout, and then soft reboot the virtual machine, the 
disk that was detach timeout was lost, but it is displayed in nova database and 
bind the vm in nova database.

Steps to reproduce
==
1. create a windows vm，attach a disk to vm. make a big io to the disk.
2. detach disk timeout
3. soft reboot
4. disk is lost


Cause Analysis
==

Because the detach disk first releases the persist xml now, when the live 
detach the disk timeout, the persist xml is also gone.
If the virtual machine is soft rebooted at this time, the virtual machine will 
be lost disk because the persistent xml is missing.


def _detach_with_retry(
   if persistent_dev:
try:
self._detach_from_persistent(
guest, instance_uuid, persistent_dev, get_device_conf_func,
device_name)
