RHBA-2012:0751 - Bug Fix Advisory

Topic

An updated virtio-win package that fixes multiple bugs and adds various
enhancements is now available for Red Hat Enterprise Linux 6.

Description

The virtio-win package provides paravirtualized network drivers for most
Microsoft Windows operating systems. Paravirtualized drivers are
virtualization-aware drivers used by fully virtualized guests running on Red Hat
Enterprise Linux. Fully virtualized guests using the paravirtualized drivers
gain significantly better I/O performance than fully virtualized guests running
without the drivers.

This updated virtio-win package includes numerous bug fixes and enhancements.
Space precludes documenting all of these changes in this advisory. Users are
directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on
the most significant of these changes:

All users of virtio-win are advised to upgrade to this updated package, which
fixes these bugs and add these enhancements.
