Folks, I have a small environment where controllers and computers run on the same nodes and yes that is a bad idea. But now what happened the machine got OOM out and crashed and stuck somewhere in Zombie stat. I have deleted all vms but it didn't work. Later I used the "virsh destroy" command to delete those vms and everything recovered but my openstack hypervisor state show" command still says you have 91 VMs hanging in DB. How do i clean up vms entered from nova DB which doesn't exist at all. I have tried the command "nova-manage db archive_deleted_rows" but it didn't help. How does nova sync DB with current stat? # openstack hypervisor stats show This command is deprecated. +----------------------+--------+ | Field | Value | +----------------------+--------+ | count | 3 | | current_workload | 11 | | disk_available_least | 15452 | | free_disk_gb | 48375 | | free_ram_mb | 192464 | | local_gb | 50286 | | local_gb_used | 1911 | | memory_mb | 386570 | | memory_mb_used | 194106 | | running_vms | 91 | | vcpus | 144 | | vcpus_used | 184 | +----------------------+--------+ Technically I have only single VM # openstack server list --all +--------------------------------------+---------+--------+---------------------------------+------------+----------+ | ID | Name | Status | Networks | Image | Flavor | +--------------------------------------+---------+--------+---------------------------------+------------+----------+ | b33fd79d-2b90-41dd-a070-29f92ce205e7 | foo1 | ACTIVE | 1=100.100.75.22, 192.168.1.139 | ubuntu2204 | m1.small | +--------------------------------------+---------+--------+---------------------------------+------------+----------+
