nova: change default machine type to Q35 #1071

Open berendt opened 3 months ago

https://docs.openstack.org/nova/latest/admin/hw-machine-type.html

10:35 < noonedeadpunk> do you think it's time for us to try to move default of hw_machine_type to q35? meaning: https://docs.openstack.org/nova/latest/admin/hw-machine-type.html
10:40 < jrosser> we do that already for some time as an override
11:10 < noonedeadpunk> I assume you have that for arm/x86 differently?
11:11 < noonedeadpunk> I'm just starring on this thing for couple of cycles already, but haven't applied it
11:11 < andrewbonney> Yes, we have 'hw_machine_type: "x86_64=q35"'
11:11 < noonedeadpunk> and that looks like a good thing as a default these days...
11:11 < noonedeadpunk> and aarch64=virt?
11:12 < andrewbonney> We don't appear to set anything explicit for aarch64
11:12 < noonedeadpunk> as I guess you can do just define all arches at once...
11:12 < noonedeadpunk> as, as it's already virt....
11:13 < noonedeadpunk> makes sense

We‘ll test this @ REGIO.cloud.

In environments/kolla/files/overlays/nova/{TESTNODES}/nova.conf

[libvirt]
hw_machine_type = q35
