Topic

Updated qemu-kvm packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux
on AMD64 and Intel 64 systems. The qemu-kvm packages form the user-space
component for running virtual machines using KVM.

This update fixes the following bugs:

  • If no listener is connected to a port on a host, output from the guest is

suppressed until a listener is connected. However, for console ports, the guest
output needs to be discarded instead. Previously, the guest kept waiting for a
listener after it wrote data to a console port. But since there was no listener,
the guest eventually became unresponsive. This bug has been fixed by changing
behavior of the "pty" socket type to not suppress output from the ports and
properly discard the data if no listener is connected. (BZ#861049)

  • With some initial guest OS installations using the QXL driver and VNC as the

display protocol, virtual machines were terminating unexpectedly with a
segmentation fault during setup and returned the "lost connection with kvm
process" error message. A patch has been provided to address this issue and
virtual machines now run properly in the described scenario. (BZ#861906)

All users of qemu-kvm are advised to upgrade to these updated packages, which
fix these bugs. After installing this update, shut down all running virtual
machines. Once all virtual machines have shut down, start them again for this
update to take effect.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
