Xen Unstable on NetBSD

[Roger Pau Monné <roger.pau%entel.upc.edu@localhost>]

Hello,

I'm trying to get xen-unstable running on NetBSD-current (version
5.99.52 because newer kernel 5.99.54 fails to boot under xen as dom0).
I was wondering if anybody has got any success in getting this to
work, I've applied the patches from xentools41, and the compilation
was successful, but xend doesn't start correctly (I haven't looked
into it closely, but looks like it fails to list PCI devices):

TypeError: argument 2 to map() must support iteration

And xl fails to run the bootloader (pygrub). I was wandering if anyone
is using it, and can give me some advice, I was trying to get unstable
to work to see if the xl console stuff was fixed, but it seems like
unstable need some more patching than just the xl console problem.

As a side note, I just saw that most patches regarding NetBSD are not
committed to the Xen repository, like the blktap drivers. Is there any
reason to not commit this modifications? I'm just asking because I
would like to try to get most of this patches added to mainstream Xen,
if the authors allow it.

Thanks, Roger.
