Paravirtualized drivers arevirtualization-aware drivers used by fully virtualized guests running on Red HatEnterprise Linux. Fully virtualized guests using the paravirtualized driversgain significantly better I/O performance than fully virtualized guests runningwithout the drivers. The virtio-win package has been upgraded to upstream version 1.7.3, whichprovides a number of bug fixes and enhancements over the previous version.(BZ#1178458)This update also fixes the following bugs:* An error in the underlying code previously caused the mouse pointer to becomedeactivated during the installation of the virtio-serial driver on Windows XPand Windows Server 2003 systems.

(BZ#1080251)* The “Manufacturer” strings in the driver properties information for thevirtio-win drivers have been corrected to be uniform and up-to-date.
