[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 set the image property architecture=ppc64 to the ppc64 image I uploaded to > glance but no success in launching VM with those images.

(not sure if my answer has been sent, sorry if duplicate) I don't touch ppc for a while but AFAIK this should work as long as you run full emulation (qemu, not kvm) as libvirt_type in nova.conf and get the qemu-system-ppc64le installed in the compute node. Assume also you get the ppc64le image to launch your instance. Expect poor performance though.

Expect poor performance though. that is my understanding also. the perfromace is accepable but not great if you can enabled the multithread tcg backend instead of the default singel tread tcg backend that is used when in qemu only mode but it still wont match kvm accleration or power on power performance. i dont think we have a way to enabel the multi thread accleration for qemu only backend via nova unfortunetly it would be triavial to add but no one has asked as far as i am aware. > > On Mon, Nov 19, 2018 at 4:12 PM Sean Mooney wrote: > > adding openstack dev. > > On Mon, 2018-11-19 at 18:08 +, Sean Mooney wrote: > > > On Mon, 2018-11-19 at 11:57 -0500, Ken D'Ambrosio wrote: > > > > On 2018-11-19 11:25, Yedhu Sastri wrote: > > > > > Hello All, > > > > > > > > > > I have some use-cases which I want to test in PowerPC > > > > > architecture(ppc64).

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?

[Openstack] how to sync quota usage our of sync in Rocky release
Dear Openstack community,
I often have nova complaining that I have exceeded my quota, these normally
happens when I node deployment fails and the resources allocated hasn't been
released. Before Rocky I used to run the command below to resync, however it
looks like it has been removed from Rocky.
[root@TEST-openstack-controller ~]# docker exec -it -u root nova_scheduler
nova-manage project quota_usage_refresh --project
abc29399b91d423088549d7446766573 --user 02132c31dafa4d1d939bd52e0420b975

...
nova-manage: error: argument category: invalid choice: 'project' (choose from
'version', 'bash-completion', 'placement', 'network', 'cell_v2', 'db', 'cell',
'floating', 'api_db')
Any idea how can I refresh the quota usage in Rocky?
