Hello All,
I have some use-cases which I want to test in PowerPC architecture(ppc64). As I dont have any Power machines I would like to try it with ppc64 VM's. Is it possible to run these kind of VM's on my OpenStack cluster(Queens) which runs on X86_64 architecture nodes(OS RHEL 7)??
I'm not 100% sure, but I'm 95% sure that the answer to your question is "No." While there's much emulation that occurs, the CPU isn't so much emulated, but more abstracted. Constructing and running a modern CPU in software would be non-trivial.
you can do this but not with kvm. you need to revert the virt dirver in the nova.conf back to qemu to disable kvm to allow emulation of other plathforms. that said i have only emulated power on x86_64 using libvirt or qemu idrectly never with openstack but i belive we used to support this i just hav enot done it personally.

I set the image property architecture=ppc64 to the ppc64 image I uploaded to glance but no success in launching VM with those images. I am using KVM as hypervisor(qemu 2.10.0) in my compute nodes and I think it is not built to support power architecture. For testing without OpenStack I manually built qemu on a x86_64 host with ppc64 support(qemu-ppc64) and then I am able to host the ppc64 VM. But I dont know how to do this on my OpenStack cluster. Whether I need to manually build qemu on compute nodes with ppc64 support or I need to add some lines in my nova.conf to do this?? Any help to solve this issue would be much appreciated.
