Possible reason
* if using cloud uefi image, it needs to install qemu-efi package in computer node, don’t know why it won’t install it automatically .
$ apt install qemu-efi
* when add new UEFI image, it needs to add new meta data parameter in Horization
hw_firmware_type=uefi

Reason
* Libvirt later version support new function, logd, it’s a new console log function, but ARM64 doesn’t support it. workaround solution is to disable it
Edit file /usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py, find
MIN_LIBVIRT_VIRTLOGD = (1, 3, 3) MIN_QEMU_VIRTLOGD = (2, 7, 0) |
Replaced it with
MIN_LIBVIRT_VIRTLOGD = (9, 9, 9) MIN_QEMU_VIRTLOGD = (9, 9, 9) |
it can avoid to call libvirt logd function.
rm -f /usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.pyc, make sure it will call .py
then, reboot service (or system)
