Bug Description
At Linaro we have several instances of OpenStack running. Some are public, some private. Some at Newton, some at Pike and now some on Queens.
And always we have to set cpu_mode = 'host-passthrough' in [libvirt] section of nova.conf file.
As we use Kolla to build and deploy Queens I added workaround there which sets cpu_mode in proper way for AArch64. But this is workaround...
So I looked at code of Nova and created some quick hack: https:/
It works for us but may not be proper way of doing it.
We use Debian 'stretch' as host system with libvirt 3.10.0 backported from 'testing'.
