RHBA-2011:1431 - libvirt bug fix update

Synopsis

libvirt bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated libvirt packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. The library provides the libvirtd daemon, which is required for virtualization management of KVM and LXC.

This update fixes the following bugs:

• Due to a programming error in the initialization code of the libvirtd daemon, the QEMU driver could have failed to find the user or group ID of the qemu application on the system. As a result, libvirtd failed to start. With this update, the error has been corrected and libvirtd now works as expected. (BZ#743557)

• If the QEMU driver failed to update information about currently allocated memory, installing a new virtual machine could have failed with the following error message:

  ERROR cannot send monitor command '{"execute":"query-balloon"}': Connection reset by peer

With this update, the driver has been modified to not consider this behavior as fatal. Installation now proceeds and finishes as expected. (BZ#747358)

All users of libvirt are advised to upgrade to these updated packages, which fix this bug. After installing these updated packages, libvirtd must be restarted. Use the "service libvirtd restart" command for this update to take effect.

Solution
