From 2f52d58c92d971bf421f461ad06eb93fb4f34981 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Wed, 16 Jan 2008 12:49:30 +0200 Subject: KVM: Move apic timer migration away from critical section Migrating the apic timer in the critical section is not very nice, and is absolutely horrible with the real-time port. Move migration to the regular vcpu execution path, triggered by a new bitflag.
