RHBA-2015:0952 - Bug Fix Advisory

Topic

Updated qemu-kvm-rhev packages that fix one bug are now available for Red Hat Enterprise Linux 7.

Description

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev packages provide
the user space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager.

This update fixes the following bug:

• On a virtual disk with a high number of sectors, the number of sectors was in some cases handled incorrectly, and converting a QEMU image failed with an "invalid argument" error. This update fixes the incorrect calculation that caused this error, and the described failure no longer occurs. (BZ#1203543)

Users of qemu-kvm-rhev are advised to upgrade to these updated packages, which fix this bug.
