Re: Xen GPLPV driver [ Re: new system configuration advice wanted ]

Nice.  I also had the "two times the charm" on the install.  Adding the 
/PATCHTPR parameter to boot.ini and disabling NIC offloading make a big 
improvement on XP network performance also.

Subject: Xen GPLPV driver [ Re: new system configuration advice wanted ]

For the record, I finally got the Xen GPLPV driver to work with a NetBSD
dom0. NetBSD was not the problem here :)
Here's what I found:
- the driver fails on a stock win XP or 2003; even installing only the Xen PCI
  driver gives a blue screen on reboot.
- After installing the service pack 2 *and* .net framework 2.0 I could
  install the drivers.
- the first installation of the drivers hang: Xen PCI is installed, the
  block and network devices are found, but no drivers are installed for
  them and the MSI seems to stall here. reboot the domU, restart the driver
  install, and this time the installation will complete. After a second reboot,
  you'll have working PV drivers.

There is a noticeable performance improvement. The main important point for
me is that now, the qemu-dm process uses nearly 0% CPU in the dom0.
