how to build xen kernel?

[reed%reedmedia.net@localhost]

I looked at NetBSD/Xen howto but don't see how to build my own custom 
kernel.

(Something changed and even though I used the PF module for two weeks I 
can't use it any more.)

I copied sys/arch/i386/conf/XEN2_DOMU to sys/arch/i386/conf/XEN2_DOMU_PF.

(I am using XEN2 since I am currently using XENU.)

Then I ran:

./build.sh -m xen -a i386 tools kernel=XEN2_DOMU_PF 

It failed after building tools with:

===> Tools built to /usr/src/netbsd-3/src/obj/tooldir.NetBSD-3.99.21-i386
===> Building kernel:  XEN2_DOMU_PF
===> Build directory:  
/usr/src/netbsd-3/src/sys/arch/xen/compile/obj/XEN2_DOMU_PF

No such file or directory

ERROR: nbconfig failed for XEN2_DOMU_PF
*** BUILD ABORTED ***

I see it is using wrong directory above.

What is correct way to build NetBSD/Xen kernels?

Am I not supposed to use "-m xen"?

How does the release team build them?

Thanks,

p.s. Once I figure this out, I can add to the NetBSD/Xen howto.
