RHBA-2012:0233 - Bug Fix Advisory

Topic

An updated python-virtinst package that fixes three bugs is now available for
Red Hat Enterprise Linux 5.

Description

The python-virtinst package provides a Python module that helps build and
install libvirt-based virtual machines.

This update fixes the following bugs:

• Running the "virt-install" command with the "--noapic" or "--noacpi" option

overrides the operating system type so that it disables the Advanced
Programmable Interrupt Controller (APIC) or Advanced Configuration and Power
Interface (ACPI) setting on a fully virtualized guest. Previously, executing the
command with the option mentioned did not take effect when installing a guest. A
patch has been applied to address this issue, and running the "virt-install"
command with the "--noapic" or "--noacpi" option specified works as expected.
(BZ#704396)

• When cloning a KVM guest by using the virt-clone utility, the new MAC address

was generated with an incorrect prefix. This was becasue the prefix allocated to
Xen was used instead of the prefix allocated to QEMU. An upstream patch has been
applied to address this issue, and the correct MAC prefix is now generated when
cloning KVM guests. (BZ#704417)

• Previously, the maxnode variables returned for virtio, scsi or paravirtualized

disks were hard-coded to number 16. As a consequence, the virt-manager utility
failed to add more than 16 paravirtualized disks, and displayed the following
message:

no more space for disks of type xvd

This update increases the number to 1024. Users can now add more than 16 new
storage devices successfully, without errors. (BZ#706398)

All users of python-virtinst are advised to upgrade to this updated package,
which fixes these bugs.

Solution

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