>Description:
XEN3_DOM0 i386 and XEN3_DOMU i386 run fine, attempting to start WinXP as a HVM-DomU results in an errormessage:

# xm create winxp
Using config file "/usr/pkg/etc/xen/winxp".
Error: (1, 'Internal error', 'Could not deallocate guard page for HVM guest.\n (25 = Inappropriate ioctl for device)')

Before output of errormessage the debugger (green letters) echoes to console:

>How-To-Repeat:
Install NetBSD 4.0 and make from Pkgsrc:
grub-0.97nb8
xentools3-3.1.4
xentools3-hvm-3.1.4
xenkernel3-3.1.4

and configure according http://www.netbsd.org/ports/xen/howto.html

# cat /usr/pkg/etc/xen/winxp
kernel = "/usr/pkg/lib/xen/boot/hvmloader"

boot='c'

>Fix:
the HVM-DomU previously worked fine using 
- NetBSD 4.0_BETA2 
- Xen 3.0.3

(current NetBSD 4.0 is a fresh install, not an update)

 Xen 3.1.4 doens't work with NetBSD 4.0. You need a kernel and userland from
 a recent netbsd-4 branch, and rebuild xentools3 and xentools3-hvm on
 this system (so that it uses the right /usr/include/xen/* files).

 Okay, a few questions please:

 I'm operating a production (file) server in a soho environment=20
 and feel comfortable with a stable release version
 1- is a version of Xen3 available, that will work with NetBSD 4.0? If =
 yes,
 from where?

 If no:=20
 2- can I use the "update" funtion of sysinst?
 3- which branch? netbsd-4-0? netbsd-4? HEAD?=20

 I would like to ask for your recommendation on the following config:
 INTEL ,DG965WH chipset (ICH8)
 4GB RAM =20
 6 AHCISATA drives =E0 300GB
 Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz
 4- which architecture? i386? amd64?

 Kind Regards
 Thomas Feddersen

 Not that I know, but netbsd-4 will probably be more stable on Xen than
 NetBSD 4.0 is :)

 Yes

 netbsd-4

 If you want Xen/amd64 you need HEAD. If you want to stay on netbsd-4
 you're stuck with i386. It'll work, but you'll be able to use only
 about 3GB RAM out of 4.

 Although to be fair we should maybe note that right now HEAD is
 loosely comparable to 5.0_BETA.

 Thanks for your fast reply, which solved my problem.
 I'll donate 50,- EUR to the NetBSD Foundation.

 One question remains:
 When I start WinXP from an Xterm, 'xm create' will not open an X window =
 on
 the current display for the virtal framebuffer. How can I get the =
 (console)
 window of WinXP?

 Kind Regards

 I think you need
 sdl = 1
 in the config file. Or set
 vnc = 1
 and use vncviewer.
