Hi
as when I installed the XenU I initialized the VCPU=1, is it
possible to change VCPU=2

As far as I know from help, it seems impossible, see the last
paragraph. But I dont want to install a new guest :(
vcpu-set domain-id vcpu-count
Enables the vcpu-count virtual CPUs for the domain in
question. Like mem-set, this command can only allocate up to the
maximum
virtual CPU count configured at boot for the domain.
If the vcpu-count is smaller than the current number of
active VCPUs, the highest number VCPUs will be hotplug removed.
This may
be important for pinning purposes.
Attempting to set the VCPUs to a number larger than the
initially configured VCPU count is an error. Trying to set VCPUs
to < 1
will be quietly ignored.
vcpu-set is for changing the number of vcpus while the guest is
running (using hotplug support), if you change it in the
configuration while the guest is shut down, then this doesn't apply.
You don't have to install a new guest, you just have to reboot.
