1.78.2. RHBA-2011:0499: kvm bug fix update

Updated kvm packages that fix one bug are now available for Red Hat Enterprise Linux 5.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the standard Red Hat Enterprise Linux kernel.

This update fixes the following bug:

* Due to a regression introduced in Red Hat Enterprise Linux 5.6, duplicate pages may have been transferred during a live migration of a KVM virtual machine. Consequent to this, when a system was under heavy load, such a migration may have failed to complete in some scenarios. This update applies a patch that reverts this regression. As a result, the live migration is now more efficient and no longer fails to complete under heavy load. (BZ#696155)

All users of kvm are advised to upgrade to these updated packages, which fix this bug. Note that the procedure in the Solution section must be performed before this update will take effect.
