[PATCH] Seperate smp from extra_params and add into default VM params

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We may need leave smp as standalone parameter of VM. Reasons I can proposal:
 1) memory is a standalone parameter, so is smp
 2) smp parameter is needed in some test case, say VM params_verify
