RHBA-2009:1423 - kvm bug fix update

Synopsis

kvm bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated kvm packages that resolve an issue are now available.

Description

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.

These updated kvm packages fix the following bug:

  • rebooting a KVM guest domain could cause the guest to fail to receive keyboard and mouse input following the reboot. This has been fixed by reinitializing keyboard and mouse state in the guest after it reboots, which resolves the issue. (BZ#517855)

Note: after installing these updated packages, the following procedure should be carried out to ensure that the fix takes effect:

  1. Stop all KVM guest virtual machines (VMs).

  2. Either reboot the hypervisor machine, or, as the superuser, remove (using "modprobe -r [module]") and reload (using "modprobe [module]") all of the following modules which are currently running (determined using "lsmod"): kvm, ksm, kvm-intel or kvm-amd.

  3. Restart the KVM guest VMs.

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