From: Zhao Liu <zhao1....@intel.com>
Different versions of PC machine support different maximum vCPUs, and
even different features have limits on the maximum number of vCPUs (
For example, if x2apic is not enabled in the TCG case, the maximum of
255 vCPUs are supported).
It is difficult to list the maximum vCPUs under all restrictions. Thus,
to avoid confusion, avoid mentioning specific maximum vCPU number
limitations here.

peripherals:
- PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1
hub.
-SMP is supported with up to 255 CPUs (and 4096 CPUs for PC Q35 machine).
