KVM: deliver PIC interrupt only to vcpu0 This patch changes the PIC interrupts delivery. Now it is only delivered to vcpu0 when either condition is met (on vcpu0): 1. local APIC is hardware disabled 2. LVT0 is unmasked and configured to delivery mode ExtInt It fixes the 2x faster wall clock on x86_64 and SMP i386 Linux guests Signed-off-by: Eddie (Yaozu) Dong <eddie.dong@intel.com> Signed-off-by: Qing He <qing.he@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
