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
Updated virto-win packages that fix two bugs are now available in the Supplementary channel of Red Hat Enterprise Linux 7.
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:
- With the previous version of the virtio drivers, high packet loss in some cases occurred on Windows guests that use the virtio interface. This update fixes the underlying code, and the affected guests no longer experience the increased packet loss. (BZ#1471073)
- Prior to this update, after migrating a Windows Server 2012 R2 guest, the guest in certain cases failed to boot and displayed a blue error screen. The bug has been fixed, and the described problem no longer occurs. (BZ#1473575)
Users of virtio-win are advised to upgrade to these updated packages, which fix these bugs.
