RHBA-2014:1444 - Bug Fix Advisory

Topic

Updated python-virtinst package that fixes several bugs and add various
enhancements 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:

• Due to a bug in the python-virtinst package, the "virt-install --graphics

spice" command did not create a spicevmc channel. This bug has been fixed and
the aforementioned command now works as expected. (BZ#853386)

• Due to a bug in the python-virtinst package, the "sparse=false" parameter of

the virt-install command was ignored and the newly crated storage was not fully
allocated. This bug has been fixed and the "virt-install sparse=false" command
now works correctly. (BZ#873545)

• Prior to this update, when the allocation of a new lvm volume was set to 0

with
the virt-install utility, no error message was returned. With this update,
virt-install has been modified to display an error message in the aforementioned
case. (BZ#1000980)

• The virt-manager utility failed to clone virtual machines (VMs) with fully

allocated logical volumes. After clicking the Clone button in virt-manager GUI,
the following message was displayed:

Sparse logical volumes are not supported

This bug has been fixed and VMs with fully allocated logical volumes can now be
cloned successfully with virt-manager GUI. (BZ#1055225)

• When the virt-install command was executed with the "device=lun" option, it

terminated with the following message:

Unknown device type 'lun'

This bug has been fixed, and lun device type is now recognized correctly by
virt-install. (BZ#1077232)

• When selecting a PCI device to be assigned to a virtual machine, the

virt-manager GUI did not display the domain of PCI devices. Consequently, it was
impossible to assign a PCI device in any domain other than zero. This bug has
been fixed and virt-manager now displays domains correctly in the described
case. (BZ#1085499)

In addition, this update adds the following enhancements:

• This update adds support for the MacVTap device driver to the python-virtinst

package. MacVTap, which facilitates virtualized bridged networking, can now be
used when installing new virtual guest machines. (BZ#855740)

• This update adds options for USB redirection to the python-virtinst package.

(BZ#1001999)

• The list of operating system variants displayed by the "virt-install
• -os-variant list" command has been updated. (BZ#1011290)
• This update enables the startup_policy parameter for the --disk option of the

virt-install command. This parameter allows to specify what to do with the disk
if the source file is not accessible. It accepts the same parameters as the
startupPolicy domain XML attribute. (BZ#1017423)

Users of python-virtinst are advised to upgrade to this updated package, which
fixes these bugs and adds these enhancements.
