Hi Edward,

Are you using Simple.Scheduler? I think it must be related to max_cores option.

max_cores default value is 16, you can override it in nova.conf

max_cores = 24

cpu_allocation_ratio (vCPU/CPU ratio) default value is 1, if you want to use more virtual cores:

cpu_allocation_ratio = ...

See:
