I've been using Openstack (Ubuntu 18.04 install following Openstack documentation) for about a year in a lab at work.

I have one VM running 24/7 with Mediawiki on it (rest is for testing).

It has been working fine until I updated packages yesterday. Here is the list of relevant packages that were updated:

2020-10-22 09:44:04 status installed neutron-common:all 2:14.3.1-0ubuntu1~cloud0
2020-10-22 09:44:06 status installed nova-common:all 2:19.3.1-0ubuntu1~cloud0
2020-10-22 09:44:12 status installed python3-nova:all 2:19.3.1-0ubuntu1~cloud0
2020-10-22 09:44:16 status installed python3-neutron:all 2:14.3.1-0ubuntu1~cloud0
2020-10-22 09:44:25 status installed neutron-linuxbridge-agent:all 2:14.3.1-0ubuntu1~cloud0
2020-10-22 09:44:29 status installed nova-compute-libvirt:all 2:19.3.1-0ubuntu1~cloud0
2020-10-22 09:44:35 status installed nova-compute-kvm:all 2:19.3.1-0ubuntu1~cloud0
2020-10-22 09:45:04 status installed nova-compute:all 2:19.3.1-0ubuntu1~cloud0

Since then, the VM does not respond (ping, ssh...).

I could list it (via Web interface or controller command line) and it showed as ACTIVE.

I rebooted the server thinking maybe something was stuck. The server came back online, the VM still ACTIVE but cannot connect to it.

My next step was to hard reboot the VM. Since then, the VM is in HARD_REBOOT state and would not move from there. I tried to shut it down, restart again the server, but no, nothing changes. When I try to shut it down it says it cannot as it is in hard reboot state.

I would at least like to be able to save some stuff that's on it (I know, I should have backed it up before the update...).

My Google searches on "openstack vm stuck hard reboot" did not help...

Do not hesitate if you need more info.

Any help would really be appreciated!
