Public bug reported: Background: We'd like to setup Nova and Devstack Upstream CI. Should support launch vm via Qemu virt_type. But host-passthrough mode(default in Aarch64) doesn't work on Qemu. So we can just use "custom" and specify CPU-model.
But actually Aarch64 don't return available cpu models list from Libvirt side. Ref:https://libvirt.org/html/libvirt-libvirt- host.html#virConnectGetCPUModelNames So we should use the specified ones from config file. And add default ones to it on Aarch64.
