Fixed In Version:		Doc Type:	Known Issue
Doc Text:	There is currently a known issue with shutting down and restarting instances after a Compute node reboot on RHOSP 17. When a Compute node is rebooted, the automated process for gracefully shutting down the instance fails, which causes the instance to have less time to shut down before the system forces them to stop. The results of the forced stop may vary. Ensure you have fresh backups for all critical workloads before rebooting Compute nodes.	Story Points:	---

Description Artom Lifshitz 2022-08-23 17:39:02 UTC

This bug was initially created as a copy of Bug #2107580

I am copying this bug because: 

Known issue release note in 17.0 ga.

Description of problem:

After a reboot of compute node, we see Tripleo_nova_libvirt_guests in the failed state.
It calls for a libvirt-guests.sh from inside the nova_libvirt container, which doesn't exist in osp17.

The release notes automation will pick up BZs with the right flags even if they're closed. With the doc text done and requires_doc_text set to +, we can close this.
