Message-Id: <1393438512-21273-1-git-send-email-drjones@redhat.com> Date: Wed, 26 Feb 2014 19:15:10 +0100 From: Andrew Jones <drjones@...hat.com> To: kvm@...r.kernel.org, linux-kernel@...r.kernel.org Cc: mtosatti@...hat.com, pbonzini@...hat.com Subject: [PATCH 0/2] x86: kvm: global clock updates This patch series addresses two issues with global clock updates. The first fixes a bug found on hosts that have a tsc marked as unstable. As global clock updates get triggered on every vcpu load in these cases, guests with a large number of vcpus have their progress nearly halted. The fix for that bug should also go to stable. The second patch in this series ensures that NTP corrections on the host, as well as on guests with all vcpus pinned, will be propagated periodically. That patch improves things, but doesn't fix a bug, thus it can be merged at a later time than the first. I've posted them together as a series, as the second one builds on the first.
