4.57. libvirt

Updated libvirt packages that fix one bug are now available for Red Hat Enterprise Linux 5.
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 libvirt library also provides nwfilter support for fine-grained filtering of the network traffic reaching guests managed by libvirt.

Bug Fix

If an LVM volume group contains a striped LVM volume, the output of the "device" field separates the multiple device paths using the comma separator. Previously, the libvirt library also used the lvs command with the comma separator, which caused regular expressions in the libvirt code to parse the output of lvs incorrectly when used on a striped LVM volume. Consequently, creation of a logical storage pool in libvirt failed if the used LVM volume group contained the striped LVM volume. Also, libvirt did not have the correct mechanism to generate multiple device XML elements for the multiple device paths of striped LVM volume. With this update, libvirt has been modified to use lvs with the "#" separator; also, the library can now parse the multiple device paths of striped LVM volumes and generate relevant XML code. Users can now create logical storage pools with striped LVM volumes and generate appropriate XML code as expected.
Users of libvirt are advised to upgrade to these updated packages, which fix this bug.
