Re: Xen 4 DOM0 with -current i386/amd64 rejects kernel?

I'm finally able to put some time toward learning to use Xen again

The boot loader loads the netbsd-XEN3_DOM0 kernel (amd64)
(netbsd-XEN3PAE_DOM0 on i386) and multiboots the "xen.gz" kernel, but
xen claims the DOM0 kernel is not an ELF binary.
I've seen this before, but I can't recall exactly what I did to resolve
it. Have you updated the bootloader? I'm definitely running xen 4.1.2
dom0s with recent NetBSD dom0 kernels (5.99.59, 5.99.64). I know there
have been issues with the bootloader and various things which have been
fixed in -current over the last year or so.
I'm not 100% sure this will work; netbsd xen kernels can't currently
load modules, and I'm not sure whether that will apply to rndseed as well.
Booting a regular kernel loads all modules from the appropriate path.
My machine's "/var" is on a different partition from the boot device
so I relocate the entropy file to "/stand/db" in "/boot.cfg" and in
I've mostly seen references to NetBSD as DOMU under XEN 4. Am I missing
something in booting XEN 4 with NetBSD as DOM0? Using a different DOM0
(i.e. a penguin-OS) is not really an option because of the disruption
it would cause.
I last tried with XEN3.3 and NetBSD 5.1_STABLE. I could boot DOM0, but
never got around to succeeding with getting a DOMU running. The DOM0
kernel lacked a number of important devices needed for my usual work,
so I had to put it aside. I had to start using -current to get better
device and application support, but last I tried with XEN3.3 it would
crash and hang on boot with a -current netbsd-XEN3PAE_DOM0 kernel.
Now that I have time and access to resources to put towards learning
XEN, it seems I'm thwarted yet again.
Don't give up! I'm definitely doing what you're looking to do, though I
don't use a PAE dom0 kernel, only amd64.
