RHBA-2012:0785 - Bug Fix Advisory

Topic

Updated virt-manager packages that fix multiple bugs and add one enhancement are
now available for Red Hat Enterprise Linux 6.

Description

The Virtual Machine Manager (virt-manager) is a graphical tool for administering
Kernel-based Virtual Machines (KVM) using libvirt.

This update fixes the following bugs:

• Prior to this update, the virt-manager tool did not change all required XML

elements when changing the disk bus of a guest from IDE to virtio, or vice
versa. As a consequence, virt-manager could create invalid XML elements that
libvirt accepted but then the guest failed to boot. This update modifies the
underlying code to change all required XML elements and guests start now as
expected. (BZ#741937, BZ#769192)

• Prior to this update, the virt-manager tool could, under certain

circumstances, receive an error from libvirt if virt-manager tried to read a
domain's information while that domain was shutting down. As a consequence, the
libvirt connection in the user interface (UI) was incorrectly closed. This
update modifies the underlying code to expect errors in this case and not close
the libvirt connection. (BZ#742055)

• Prior to this update, the glib integration did not work correctly. As a

consequence, serial consoles of virtual machines could stall when transferring
large amounts of data. This update modifies the underlying code to allow the
transfer of larger amounts of data without stalling. (BZ#747490)

• Prior to this update, graphical scaling did not work for SPICE graphics in the

virt-manager tool. This update modifies the underlying code to connect the UI
scaling selection element to the spice back end. (BZ#750225)

• Prior to this update, the virt-manager tool could close with a segmentation

fault if the user deleted several storage volumes in quick succession due to
data locking when deleting the storage volume. This update modifies the
virt-manager threads to allow deleting of storage volumes in quick succession.
(BZ#803600)

• Prior to this update, the virt-manager tool could, did not correctly clean up

certain internal state. As a consequence, closing and reopening a graphical
window of a guest did not reopen the graphical console. This update modifies the
underlying code to ensure that the graphical console connection is correctly
reopened. (BZ#811316)

• Prior to this update, the virt-manager tool did not correctly using the

graphics listen address attribute in the configuration of the virtual machine,
and would always try to connect to the guest with an SSH tunnel. This could
break graphical console connections if "listen=" was set to an explicit
interface address. This update modifies the underlying code to ensure that
virt-manager now correctly connects to these addresses. (BZ#816279)

This update also adds the following enhancement:

• Prior to this update, the default disk image format for disk images used for

newly created virtual machines was "raw" and could not be changed. This update
adds the new "qcow2" option. (BZ#716673)

All users of virt-manager are advised to upgrade to these updated packages,
which fix these bugs and add this enhancement.
