We don't actually have any non-x86 hardware at the moment - we're just
looking to run certain workloads in qemu full emulation mode sans KVM
extensions (we know there is a huge performance hit - it's just for a
few very specific things). The hosts I'm talking about are normal
intel-based compute nodes with several different qemu packages installed
(arm, ppc, mips, x86_64 w/ kvm extensions, etc.).
Is nova designed to work in this kind of scenario? It seems like many
pieces are there, but they're just not quite tied together quite right,
or there is some config option I'm missing.
As far as I know, nova doesn't make anything arch-specific for QEMU.
Nova will execute some qemu commands like qemu-img but as far as the
virt driver, it goes through the libvirt-python API bindings which wrap
over libvirtd which interfaces with QEMU. I would expect that if you're
on an x86_64 arch host, that you can't have non-x86_64 packages
installed on there (or they are noarch packages). Like, I don't know how
your packaging works (are these rpms or debs, or other?) but how do you
have ppc packages installed on an x86 system?
