Hello, I’m following a-universe-from-nothing (2024.2) here <https://github.com/stackhpc/a-universe-from-nothing/blob/stable/2024.2/README.rst>.in order to upskill on OpenStack deployment technologies. I’ve played a bit with the RDO-based installs, but a-u-f-n seemed closer to reality. My host VM is running Jammy (hostname: aufn-seed-jammy), with 64GB RAM and 100GB disk. I successfully made it through "Configure and deploy OpenStack to the control plane”, had running “seed”, “controller0”, “compute0” VMs, and was able to login to Horizon. I thought, “great! Let’s snapshot it all and keep going." So, I shutdown the host VM, aufn-seed-jammy (the one that is hosting “seed”, “controller0”, and “compute0”. I created a snapshot. I then restarted the host VM. The host VM (aufn-seed-jammy), and the seed VM started and I’m able to “ssh stack@seed” from the Host VM without problems. But… neither “controller0” nor “compute0” started up on their own. After sourcing Kayobe, from the host VM, I can “sudo virsh list —all” and see the following: (kayobe in ${KAYOBE_ENVIRONMENT:-base}) ubuntu@aufn-seed-jammy:~/deployment/src/kayobe-config/etc/kayobe$ sudo virsh list --all Id Name State ------------------------------ 1 seed running - compute0 shut off - controller0 shut off I then tried to manually start them: (kayobe in ${KAYOBE_ENVIRONMENT:-base}) ubuntu@aufn-seed-jammy:~/deployment/src/kayobe-config/etc/kayobe$ sudo virsh start controller0 error: Failed to start domain 'controller0' error: Cannot get interface MAC on 'p-contr0-0-tap': No such device I then ran an “ip a” to see what interfaces I have, but did not find one with that name.

I’m not clear on and would appreciate any suggestions and advice on the following: 1) What are the commands and sequence to properly/cleanly bring down an “a-universe-from-nothing” based environment? 2) What are the commands and sequence to properly/cleanly start up an “a-universe-from-nothing” based environment? Thank you in advance for your time and considerations.
