RHBA-2011:0782 - Bug Fix Advisory

Topic

Updated virtio-win packages that fix multiple bugs and add one enhancement are
now available for Red Hat Enterprise Linux 6.

Description

The virtio-win package provides para-virtualized network drivers for most
Windows operating systems.

This update fixes the following bugs:

• Previously, free eviction memory did not work correctly on Windows guests when

using virtio-balloon drivers. This update changes the memory to the set value.
(BZ#610787)

• Previously, the virtual machine aborted unexpectedly when it ran on Windows XP

SMP guests. With this update, the guest no longer aborts. (BZ#630536)

• Previously, the netperf test on the Windows 2008 and Windows 7 guests with

virtio network caused the network to become unresponsive. This update corrects
the Network Interface Card (NIC) driver. Now, the network stays available.
(BZ#630830)

• Previously, the whql virtio-serial test on Windows 2008 R2 guests caused the

subjob "Run SimpleIOStress" to become unresponsive. This update resolves this
issue. Now, this subjob runs as expected. (BZ#633243)

• Previously, the hal.dll file was missing after quitting the Windows XP guest

several times. Due to this issue, Windows did not start. This update resolves
this issue. The Windows XP guest starts as expected. (BZ#634828)

• Previously, Windows approved drivers caused an incorrect warning when

installing them on Windows 7 x86. This update rebuilds the driver package and
CAT file using INF2CAT. (BZ#649773)

• Previously, virtio-win did not generate crash dump files after encountering a

Stop Error (BSOD) of Windows guests. The subjob "Execute
Commond_Scenario_Stress_With _IO Script" was aborted. With this update, the
subjob passes without further errors. (BZ#669314)

• Previously, the virtio block driver failed to upgrade and aborted with a BSOD.

This update resolves this issue. Now, the virtio block driver upgrades as
expected. (BZ#669597)

• Previously, the job "DPWDK-HotReplace-Device Test-Verify driver support for D3

power state" failed with a BSOD. This update runs this update
successfully.(BZ#669633)

• Previously, the virtio serial driver caused a BSOD when installing or running

whql jobs. This update installs the driver and passes all related whql jobs.
(BZ#670713)

• Previously, the viostor.sys file version was not updated between builds. Due

to this issue, the RHEV-Block installer could not update this .sys file. This
update resolves this issue. Now, the viostor.sys file is updated as expected.
(BZ#679344)

• Previously, windows guests with 30 virtio serial ports aborted booting with a

BSOD. With this update, windows guests can boot as expected. (BZ#688839)

• Previously, the virtio block job "Embedded Signature Verification" failed.

This update passes this verification without further errors. (BZ#690713)

This update also adds the following enhancement:

• Previously, the virtio-serial windows driver had a write-size limitation. This

limitation caused specific changes to devices using virtio-serial ports in qemu.
With this update, write-size is unlimited. (BZ#617000)

All virtio-win users are advised to upgrade to these updated packages which fix
these bugs and add this enhancement.
