<br />No, not without restarting the guest from scratch. Whilst it's possible
<br />to REDUCE the processor count, you can't increase it after it's been
<br />started [actually, the technicality of it is that there's a MAX_CPU
<br />count in the domain config parameters, which is hidden from the config
<br />files at present, but that is the number of VCPU's "reserved" when the
<br />domain is set up, and with a normal config file, you get MAX_VCPUS=VCPUS
<br />at the domain creation].

So if I want to get a guest with 2 VCPUs, I must install a new one? no other
