Synopsis
virtio-win bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated virtio-win package that fixes two bugs 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 update fixes the following bugs:
- A bug in the virtio serial driver could cause a Stop Error (also known as Blue
Screen of Death, or BSoD) which occurred on a guest machine when transferring
data from the host. This update fixes the bug in the driver so that the guest
machine no longer crashes with Blue Screen of Death in this scenario.
(BZ#838523)
- The QXL driver included in the previous version of the virtio-win package was
not digitally signed. The QXL driver provided in this update in digitally
signed. (BZ#838655)
All users of virtio-win are advised to upgrade to this updated package, which
fixes these bugs.
