CPU freq is per-core. The only way is to fix it in the database and next stop/start VMs.
Here is the SQL expr like the following: update service_offering_view set limit_cpu_use=0 where name like 'abc%' and domain_path='/cde/'; сб, 2 мар. 2019 г. в 15:11, Fariborz Navidan <mdvlinqu...@gmail.com>: > Also, how do I disable cpu cap for existing vms? > > On Sat, Mar 2, 2019 at 11:35 PM Fariborz Navidan <mdvlinqu...@gmail.com> > wrote: > > > Hi, > > > > Indeed I didn't realized the answer.
