RHBA-2012:0500 - 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.

This update fixes the following bug:

• When a live migration of a guest was terminated abruptly (using the Ctrl+C key combination), the libvirt daemon could have failed to accept any future migration request of that guest with the following error message:

  error: Timed out during operation: cannot acquire state change lock

This update adds support for registering cleanup callbacks which are called for a domain when a connection is closed. The migration API is more robust to failures, and if a migration process is terminated, it can be restarted on a subsequent command. (BZ#806206)

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
