From 09cec754885f900f6aab23801878c0cd217ee1d6 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Mon, 23 Mar 2009 15:11:44 +0200 Subject: KVM: Timer event should not unconditionally unhalt vcpu. Currently timer events are processed before entering guest mode. Move it to main vcpu event loop since timer events should be processed even while vcpu is halted. Timer may cause interrupt/nmi to be injected and only then vcpu will be unhalted.
