Public bug reported: """ It would be great if Nova supports instances with a different architecture than the host. An use case would be run aarch64 guests in a x86_64 compute node. """
In order to use boot an aarch64 guest in a x86_64 host we need to use UEFI. However, Nova always uses the UEFI loader considering the host architecture. The guest architecture should be considered instead. in livbvirt.driver.py: "for lpath in DEFAULT_UEFI_LOADER_PATH[caps.host.cpu.arch]" Environment =========== Tested using the master branch (29/10/2020) Other ===== I'm now opening target bugs for this issue.
