NOTE:  This is on Windows 2008 w/ SP2

The output from 'devcon find * | findstr "PCIIDE"' is the following:
----------
PCIIDE\IDECHANNEL\4&80D05ED&0&0                             : ATA
Channel 0
PCIIDE\IDECHANNEL\4&80D05ED&0&1                             : ATA
Channel 1

-----------

In this case, the boot drive is connected to ATA Channel 0.  Note the
output when I attempt to disable the ATA Channel 0 when the boot device is
attached to it:
---------------
D:\vista\x86>devcon disable @"PCIIDE\IDECHANNEL\4&80D05ED&0&0"
PCIIDE\IDECHANNEL\4&80D05ED&0&0                             : Disable
failed
--------------

If I attempt to disable "Channel 1", I am able to get this:
-------------
D:\vista\x86>devcon disable @"PCIIDE\IDECHANNEL\4&80D05ED&0&1"
PCIIDE\IDECHANNEL\4&80D05ED&0&1                             : Disabled
on reboot

The 1 device(s) are ready to be disabled. To disable the devices, restart
the
devices or reboot the system .
-------------

Also, Note the way we're working around this, for your information:
1. Install RH PV Drivers
2. Before reboot, Go into registry and set ATAPI service to not start on
boot
3. Reboot
4. Issue "devcon disable" against Channel 0 (this succeeds right away).
5. Edit registry, set ATAPI to start on boot
6. Reboot.

Then everything works as planned.

Thanks, I think it is fine.  I wasn't sure if the part after "4&" was changing between systems and I assumed it was not; however, it does.

I already wrote the Vista version of set-ide, this test was only to confirm that I was not on the wrong track.  I'll backport the patch to the InstallShield installer after more testing.

Can you please detail in IT326370 what are the aspects that are _not_ relevant to installation?

Created attachment 361268 [details]
patch set overhauling set-ide

Fixed in 1.0.90-1.

RPMs available from http://people.redhat.com/pbonzini/xenpv-win-1.0.91-1

The next drop will avoid devcon/set-ide completely to do this part of the installation (the set-ide changes for W2K8 were just a stopgap measure).  Thanks for the testcase!

1.Install win20008 guest
2.Install xenpv driver and reboot the computer
3.Go to device manager
It will show RHEL Removed FV Device
