There is a better explanation in the OpenStack docs :-) with an example how to get 50% slower (not something my users ask for often)
cpu_quota & cpu_period seems to give it according to http://docs.openstack.org/admin-guide-cloud/compute-flavors.html Tim On 04/03/16 15:59, "Jonathan Proulx" <j...@csail.mit.edu> wrote: >On Fri, Mar 04, 2016 at 11:52:33AM +0800, gustavo panizzo (gfa) wrote: >:On Thu, Mar 03, 2016 at 03:52:49PM -0500, Jonathan Proulx wrote: >:> >:> I have a user who wants to specify their libvirt CPU type to restrict >:> performance because they're modeling embeded systems. >:> >:> I seem to vaguely recall there is/was a way to specify this either in >:> the instance type or maybe even in the image metadata, but I can't >:> seem to find it. >:> >:> Am I delusional or blind? > > >As previous posters pointed out I was a bit delusional obviously cpu >type only limits instruction set & is useful for bianry compatibility >but mothing to do with speed limiting or equalization. > >:you can use >:https://wiki.openstack.org/wiki/InstanceResourceQuota > >Thanks I think that has the bits I'm looking for.
