An updated xenpv-win package that fixes multiple bugs is now available for Red Hat Enterprise Linux 5.
The xenpv-win package contains installation images for para-virtualized drivers for guests running Microsoft 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.
- If a locked Windows 2003 guest with the xenpv-win driver installed was shut down or rebooted by executing the "xm shutdown" or "xm reboot" command, the commands became invalid when attempting to execute them again after the machine was unlocked. The underlying source code has been modified so that Windows 2003 guests can be shut down and rebooted repeatedly regardless of whether the guest has been locked or not.
- Due to a hard-coded 0 index in the code that manipulates the event channel pending mask, the xenpv-win driver could become unresponsive during boot on EC2 Large Instances. This problem has been fixed, and xenpv-win no longer hangs in this scenario.
- This version of xenpv-win has been certified through the Microsoft Server Virtualization Validation Platform (SVVP) program.
All users of are advised to upgrade to this updated package, which fixes these bugs.
