Trying to enable some alternate (non-x86) architectures on xenial +

(https://docs.openstack.org/nova/queens/configuration/config.html) in
image_properties_default_architecture. From what I can tell, the
scheduler works correctly and instances are only scheduled on nodes that
have the correct qemu binary installed. However, when the instance
request lands on this node, it always starts it with qemu-system-x86_64
rather than qemu-system-arm, qemu-system-ppc, etc. If I manually set
the correct binary, everything works as expected.
Am I missing something here, or is this a bug in nova-compute?
image_properties_default_architecture is only used in the scheduler
filter to pick a compute host, it doesn't do anything about the qemu
binary used in nova-compute. mnaser added the config option so maybe he
can share what he's done on his computes.
Do you have qemu-system-x86_64 on non-x86 systems? Seems like a
package/deploy issue since I'd expect x86 packages shouldn't install on
a ppc system and vice versa, and only one qemu package should provide
the binary.
