RHBA-2016:1372 - Bug Fix Advisory

Topic

Updated qemu-kvm-rhev packages that fix one bug are now available for Red Hat Enterprise Virtualization Hypervisor 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:

• After applying the fix for security issue CVE-2016-3712, the installation of Windows 7 guests on Red Hat Enterprise Virtualization Hypervisor was not possible due to unmodifiable registers. This update introduces a new register set, sr_vbe, to be used instead of vga registers in Windows 7 guests. As a result, the vga registers no longer cause the guest installation to fail. (BZ#1347185)

Users of qemu-kvm-rhev are advised to upgrade to these updated packages, which fix this bug. After installing this update, shut down all running virtual machines, and then start them again for this update to take effect.
