[kvm-devel] KVM: LAPIC: ignore pending timers if LVTT is disabled

Only use the APIC pending timers count to break out of HLT emulation if the timer vector is enabled. Certain configurations of Windows simply mask out the vector without disabling the timer. Signed-off-by: Marcelo Tosatti <[EMAIL PROTECTED]> diff --git a/arch/x86/kvm/lapic.c b/arch/x86/kvm/lapi

[kvm-devel] [PATCH] Add support for a configuration file
