If the user pressed the X button on the "Customize configuration before install" dialog box, the box closed and the installation started instead of being canceled. With this update, pressing the new Cancel button in the dialog box removes the custom changes and displays the "New VM" wizard. The X button now correctly performs the cancel action.

The virt-manager utility offered sound card models in the user interface (UI) that are not supported at the QEMU level. As a consequence, selecting one of these models prevented a guest from starting. Unsupported models are now hidden so that there is no option to generate a broken guest configuration.

When performing tunneled migration using the virt-manager utility, the migration failed with an error message. With this update, the proper URI is now generated when performing peer-to-peer migration. As a result, tunneled migration now works as expected.

The virt-manager utility offered to create the SCSI (Small Computer System Interface) and USB devices in the UI. These options are not supported at the QEMU level, therefore selecting one of these models prevented a guest from starting. Unsupported models are now hidden so that there is no option to generate a broken guest configuration.

Previously, virt-manager did not properly escape reserved characters in domain names when listing them in the main list of virtual machines. If a virtual machine had any reserved XML characters in its name, the name was incorrectly displayed in the list of virtual machines. With this update, virt-manager properly escapes reserved characters in the names of virtual machines, which are correctly displayed as a result.

When monitoring the disk I/O statistics in virt-manager, the utility used different scales on graphs for various machines. As a consequence, a graph for a virtual machine with low I/O activity displayed very similar information as a graph for a machine with high I/O activity. The virt-manager utility is now modified to show all visible graphs on the same scale, adjusted dynamically to the highest reported I/O value. Graphs can now be reliably compared across various virtual machines.

Previously, virt-manager incorrectly compared USB devices of a running guest to the USB devices from its offline configuration file. A hot unplugged USB device did appear again after the guest had been rebooted. Now, comparisons work correctly for online and offline guests and hot unplug removes the USB device for all subsequent starts.

The virt-manager utility now provides an option to set the iSCSI Qualified Name (IQN) value for an iSCSI pool.

With this update, virt-manager now uses the Simple Protocol for Independent Computing Environments (SPICE) graphics for new guests by default. This allows for audio streaming and better graphics performance.

Previously, only local guest virtual machines were allowed to be installed by specifying a URL tree. With this update, virt-manager can now provision also remote guests using a URL tree.

The virt-manager utility now allows managing Linux Containers (LXC) guests. This includes basic life cycle management (start, stop, pause) and creation of application containers.
