RHBA-2013:1604 - Bug Fix Advisory

Topic

Updated python-virtinst packages that fix several bugs and add one enhancement
are now available for Red Hat Enterprise Linux 6.

Description

The python-virtinst package contains several command-line utilities, including
virt-install for building and installing new virtual machines, and virt-clone
for cloning existing virtual machines.

This update fixes the following bugs:

• If there were duplicate USB devices connected to a host device, passing the

vendorId or productId value to the "--host-device" option caused the
virt-install utility to terminate with the following message:

ERROR 'vendor' and 'product', or 'bus' and 'device' are required.

This message did not inform about the duplicate devices, which was the cause of
the error. The message has been modified to:

ERROR 15e1:2007 corresponds to multiple node devices

As a result, user is now informed about the true cause of the failed
installation. (BZ#861972)

• Previously, when the "--disk" parameter contained the hash ("#") character,

incorrect error messages were displayed. This bug has been fixed and error
messages now inform about the unsupported character correctly. (BZ#916875)

• Prior to this update, the virt-install utility created sparse logical volumes

by default. However, sparse logical volumes require further configuration and
therefore should be created only by advanced users or management applications.
With this update, non-sparse mode is the default and only available setting.
(BZ#921480)

• Under rare circumstances, the virt-clone utility displayed incorrect speed

statistics during the clone operation. This bug has been fixed, and correct
speed values are now displayed when virt-clone is in action. (BZ#946972)

• Under certain circumstances, when there was the ".treeinfo" file available on

the system, the virt-install utility attempted to get image information from
this file. In case ".treeinfo" did not contain this information, virt-install
terminated unexpectedly. This bug has been fixed, and virt-install now uses
default values in case of incomplete ".treeinfo". (BZ#954262)

• Previously, an attempt to change the model type of a video device from "qxl"

led the virt-manager utility to return the following error message:

Error changing VM configuration: XML error: ram attribute only supported for
type of qxl

The underlying source code has been modified, and the model type of a video
device can now be changed without complications. (BZ#980334)

In addition, this update adds the following enhancement:

• This update provides a revised list of installation environments that are

supported by the virt-manager utility. (BZ#958496)

Users of python-virtinst are advised to upgrade to these updated packages, which
fix these bugs and add this enhancement.
