RHBA-2011:0853 - Bug Fix Advisory

Topic

An updated xenpv-win package that fixes various bugs is now available.

Description

The xenpv-win package contains installation images for para-virtualized drivers
for guests running Windows XP or later on Red Hat Enterprise Linux hosts.
Para-virtualized drivers provide significant network and disk I/O performance
improvements for fully virtualized guests over the same guests running with
fully virtualized drivers.

This updated package provides CD-ROM images containing the para-virtualized
network and disk drivers for instances of Windows XP or later, running on a Red
Hat Enterprise Linux host.

This updated xenpv-win package includes fixes for the following bugs:

• Running the "NDISTest 6.5 (MPE)" job from the Windows Logo Kit on a RHELNET

driver caused the Windows guest to crash. With this update, the RHELNET driver
passes the "NDISTest 6.5 (MPE)" job from the Windows Logo Kit. (BZ#656776)

• Shutting down a Windows guest through hibernation caused a crash of the guest.

With this update, the RHELSCSI driver behaves properly when guests are being
hibernated. (BZ#679144)

• Uninstalling a driver package on a Windows Server 2008 guest would cause the

guest to crash on every subsequent reboot. With this update, the guest will work
correctly after uninstalling the driver package. (BZ#679669)

• Applications that were submitting a large number of disk I/O requests directly

to the drivers could cause them to leak memory in the guest. In particular, this
happened when running the "Disk Stress" job from the Windows Logo kit on Windows
Server 2003 guests. With this update, the memory leak has been fixed and the
drivers pass the "Disk Stress" job on all supported versions of Windows.
(BZ#681440)

• Running the "NDISTest 6.0" job from the Windows Logo Kit failed on Windows XP

and Windows Server 2003 guests. With this update, the RHELNET driver passes the
"NDISTest 6.0" job on all supported versions of Windows. (BZ#681762)

• The RHELSCSI driver could fail to load on 32-bit Windows Server 2008 guests

after ~100 disable/enable cycles. With this update, the RHELSCSI driver sustains
a much higher number of disable/enable cycles. (BZ#689748)

• The binaries in this release of the xenpv-win driver are certified by the

Microsoft Windows Hardware Quality Labs ("WHQL"). WHQL certification ensures
that all components install and uninstall properly and do not interfere with
other system components, and that each component interoperates well with other
system components. (BZ#584249)

All users of xenpv-win are advised to upgrade to this updated package, which
resolves these issues.
