[Openstack] Create VMs with Power architecture(ppc64) on OpenStack running on x86_64 nodes??
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 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. -- Thank you for your time and have a nice day, With kind regards, Yedhu Sastri _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack

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. -Ken

I think that within an OpenStack cluster you'd have to dedicate a whole compute node to running ppc64 and have it advertise the architecture as ppc64. Then when you ask for "architecture=ppc64" it should land on that node. If this is for "development, testing or migration of applications to Power" have you checked out these people? They provide free Power VMs. http://openpower.ic.unicamp.br/minicloud/ Chris _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack

Then when you ask for "architecture=ppc64" it should land on that node. you know it says it for arm but you might be able to do this by setting hw_machine_type https://github.com/openstack/glance/blob/master/etc/metadefs/compute-libvirt... i know you can set the hw_machine_type to set teh default for all instace on a host https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.hw_... but i can rememebr it image property is alys used or if its just used for arm as the docs suggest.
the hypervisor_type in the image should be set to qemu to make sure you avoid the kvm hosts as they will not work for cpu emulation.

Thank you all for the valuable informations. So I will try with one compute node which has qemu as libvirt_type in nova.conf and then I hope I can host ppc64 VM's on that node. On Mon, Nov 19, 2018 at 10:47 PM Sean Mooney <smooney@redhat.com> wrote:
