[libvirt] 'host-passthrough' for arm64

Hello guys, I'm trying to come up with basic OpenStack support for arm64 node. I'd like to use 'libvirt_cpu_mode=host-passthrough' configuration option with Nova which issues cpu mode='host-passthrough' to libvirt xml config. But with this option passed libvirt crashes with 'error: unsupported

[libvirt] [PATCH] qemu: Implement a stub cpuArchDriver.baseline() handler for arm

Openstack Nova calls virConnectBaselineCPU() during initialization of the instance to get a full list of CPU features. This patch adds a stub to arm-specific code to handle this request (no actual work is done). Signed-off-by: Oleg Strikov oleg.stri...@canonical.com --- This is a port

[libvirt] [PATCH] qemu: Implement a stub cpuArchDriver.compare() handler for arm and aarch64

Libvirt calls cpuArchDriver.compare() while doing guest migration. We don't have any logic to distinguish between different arm and aarch64 models that's why this patch allows migration to any host. Signed-off-by: Oleg Strikov oleg.stri...@canonical.com --- src/cpu/cpu_aarch64.c |9
