RHBA-2009:1424 - Bug Fix Advisory

Topic

Updated libvirt packages that resolve an issue are now available.

Description

The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remotely managing virtualized systems.

These updated libvirt packages fix the following bug:

• the PIT clock is the programmable interrupt timer clock, which triggers

interrupts at certain counts, and is the default clock for Red Hat
Enterprise Linux KVM guests. Guests which used the PIT experienced clock
drift due to interrupt re-injection. The "-no-kvm-pit-reinject" option has
now been added to the KVM command line, which solves potential clock drift
on Red Hat Enterprise Linux KVM guests. (BZ#517903)

All libvirt users are advised to upgrade to these updated packages, which
resolve this issue.
