RHBA-2013:0575 - Bug Fix Advisory

Topic

Updated libvirt packages that fix one bug are now available for Red Hat
Enterprise Linux 5.

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 libvirt
library also provides nwfilter support for fine-grained filtering of the network
traffic reaching guests managed by libvirt.

This update fixes the following bug:

• 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. (BZ#903600)

Users of libvirt are advised to upgrade to these updated packages, which fix
this bug.
