This basically says your kernel image is invalid

This confirms that the kernel image you''re trying to boot is
incompatible
with your host OS.

Are you sure that

/data/xenimages/netbsd/netbsd-INSTALL_XEN3_DOMU

Is a kernel image, and not a virtual disk image ?  If it really is a krenel
image, make sure it is the same architecture as your dom0 - ie x86_64.

Regards,
Dan.

Yes, I have run into the same thing.  The problem is that NetBSD
doesn''t have a PAE enabled kernel available, and FC6 is compiled to use
PAE.  Unfortunately, you are probably out of luck unless:

1)  You recompile the FC6 kernel and HV to be non-PAE.  It''s fairly
straightforward, but the problem then is that your other FC6 guests
won''t work (because then you will have non-PAE dom0, but PAE guests).

2)  Find someone willing to make NetBSD use PAE.

There are also some bimodal (meaning that both PAE and non-PAE guests would work
on a PAE dom0) patches going into upstream Xen, but I''m not sure if we
would put those into FC6 (or they would wait for FC7 or later).

3) Use Xen Binaries from XenSource, which provide a selection.

4) Use another distribution as dom0 - SuSE and Debian let you chose if
you want PAE or not.
This is for sure only a solution when you don''t need PAE :)

Best solution would be really if the NetBSD team could upload two
versions of their kernels, so everybody can use them...

I also had this problem, but I remember in one of the logfiles there
was actually an error message telling something useful like "non-PAE
kernel on PAE host" something like that.
