An updated python-virtinst package that fixes several bugs is now available for Red Hat Enterprise Linux 6.
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.
- Previously, the virt-manager tool generated an invalid XML code when defining a bridge interface. As a consequence, bridge devices could not be created. With this update, virt-manager generates the correct definition XML and creating bridge devices no longer fails.
- Prior to this update, input from the user was validated incorrectly by the virt-install utility. Consequently, a non-sparse LVM could not be created and an error message was displayed. This update fixes the input validation and virt-install can now create a non-sparse LVM as expected and an error no longer occurs.
- Previously, changing the processor type to "copy from host" caused all CPU extensions to be copied manually, even extensions that were not supported for migration. As a consequence, running the "virsh save" command after reboot failed, and an error message was displayed. With this update, when the "--cpu=host" option is specified, the "cpu mode='host-model'" option is used. As a result, unsupported extensions are not no longer manually copied, and the described error no longer occurs.
Users of python-virtinst are advised to upgrade to this updated package, which fixes these bugs.
