Queued, thanks. Paolo

QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL VGA BIOS.
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. Suggested-by: Daniel P.
