We are running Rocky and we have the allocation bug because we set cpu_allocation_ratio and ram_allocation_ratio to 1 on the controllers but not on the hypervisors, so the hypervisors are oversubscribed. When we try to reboot a VM when the HV is short memory, the VM is deleted from the HV. It still exists in Openstack but not on the HV. Is it possible to recover a VM from this state?
