RHBA-2011:0637 - Bug Fix Advisory

Topic

An updated virt-manager package that provides bug fixes and adds
enhancements is now available for Red Hat Enterprise Linux 6.

Description

Virtual Machine Manager (virt-manager) is a graphical tool for
administering virtual machines for KVM, Xen, and QEMU. virt-manager can
start, stop, add or remove virtualized devices, connect to a graphical
or serial console, and view resource usage statistics for existing
virtualized guests on local or remote machines. It uses the libvirt API.

The virt-manager package has been upgraded to upstream version 0.8.6,
which provides a number of bug fixes and enhancements over the previous
version.

Interesting enhancements include:

• Option to configure guest CPU model, including an option to mimic

host CPU in the guest, which can greatly improve performance. (BZ#647306)

• Option to configure CPU topology (sockets, cores, threads). This

enables using more CPUs with OS which have a support limit on sockets
(the default vcpu type).

• Cancellation and progress reporting for 'Save' and 'Migrate'

operations.

• Option to see the error message if a hotplug operation fails. This

can be useful in determining if hotplug for the specified device type
is supported and failure was expected. (BZ#613546)

• Use of ICH6 sound device model by default.

Interesting bug fixes include:

• Previously, if selecting 'Customize before install' at the end of the

'New VM' wizard and the install process failed, any custom changes made
were forgotten if the installation was re-run. This is now fixed. (BZ#619894)

• Previously, the 'New VM' wizard incorrectly capped maximum guest

memory at 32GB. This limitation has been removed. (BZ#640781)

All users of Red Hat Enterprise Linux 6 should upgrade to these updated
packages.
