I tried to run:
ldm set-vcpu 2 primary
ldm add-config new.config
reboot the Primary/Control Domain
However I still see 4 vcpu for the Primary/Control Domain.
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv SP 4 4G 33% 3m
ldg1 inactive ----- 4 1G
ldg2 inactive ----- 4 2G
Any suggestion will be great.
Thanks.

Roberto,
Vpcu's are only dynamically re-assignable if the domains involved do not
have MAU's bound to them. From the message you are seeing that is the
situation you have.
Having MAU's in a domain implies a required path to access them through
a vcpu, removing vcpus dynamically could potentially remove the path to
the mau hence making that resource unintentionally unavailable to the
domain as a direct consequence of removing vcpus.
In order to stop that happening, once you have MAU's in a domain, you
can't dynamically reconfig vcpus in that domain, it becomes a delayed
reconfig property as noted in the message that you see.. If you reboot
the domain you are re-configing, you will see the new vcpu count as
expected.
This is well documented in the Admin Guide.
