RHBA-2015:1387 - Bug Fix Advisory

Topic

Updated perl-Sys-Virt packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The Sys::Virt module provides a Perl XS binding to the libvirt virtual machine
management APIs. This allows machines running within arbitrary virtualization
containers to be managed with a consistent API.

This update fixes the following bugs:

• Previously, using the libvirt-tck utility to display virtual CPU (VCPU)

information only printed a part of the expected diagnostics. With this update,
the get_vcpu_info() function handles VCPU flags properly, and libvirt-tck
displays the full extent of the expected information. (BZ#905836)

• Prior to this update, using the libvirt-tck utility to find the parent device

of a node device with no parent incorrectly returned a "libvirt error code: 0"
error message. Now, it is valid for the virNodeDeviceGetParent() function to
return NULL if the parent device is nonexistent, and the error message is no
longer displayed. (BZ#908274)

Users of perl-Sys-Virt are advised to upgrade to these updated packages, which
fix these bugs.

Solution

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