Re: [openstack-dev] [Nova] Blueprint: standard specification of guest CPU topology

2013-12-21 Thread Chet Burgess
After reading up on the proposed design I have some concerns, primarily around the use of image properties to represent the topology. While I see the relationship between images and CPU topology (as referenced in the wiki Windows licenses and its restrictions on sockets being a prime example) i

Hi, I think the concept of allowing users to request a cpu topology, but have a few questions / concerns: > > The host is exposing info about vCPU count it is able to support and the > scheduler picks on that basis. The guest image is just declaring upper limits > on > topology it can support.

For attention of maintainers of Nova virt drivers A while back there was a bug requesting the ability to set the CPU topology (sockets/cores/threads) for guests explicitly https://bugs.launchpad.net/nova/+bug/1199019 I countered that setting explicit topology doesn't play well with booting im
