Hello,
I’m following a-universe-from-nothing (2024.2)
here.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
------------------------------
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.
(kayobe in ${KAYOBE_ENVIRONMENT:-base}) ubuntu@aufn-seed-jammy:~/deployment/src/kayobe-config/etc/kayobe$ ip a

The only interfaces starting with “p-“ are “p-braio-ovs@p-braio-phy” and “p-braio-phy@p-braoi-ovs”.
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.
Kind regards,
Jordan.
