[Kimchi-devel] [kimchi-devel][PATCH 1/2] Fix update vcpu count: Check available vcpu count before update

From: Royce Lv <lvroyce(a)linux.vnet.ibm.com&gt; Currently we just check vcpu count does not exceed host available count when topology specified. Actually vcpu count also need to be checked when only vcpu specified. Move this check outside topology check and add it to param update.
