This usually means that the image you're trying to load isn't a valid 
ELF image (or is of the wrong 'arch' for the hypervisor, e.g. PAE kernel
on 32 bit xen). 

What's in /var/log/xen/xend.log and /var/log/xen/xend-debug.log ? 



cheers,

S.

yeah, I found it by tracing xend; it looks like the RPMs at xensource
and in FC6 are for PAE kernels, which plan 9 is not.

Guess I build from source now.

Thanks for the pointers, though.

Does this mean there's a Xen 3 enabled Plan 9?

Cheers,

yes, Richard Miller bit the bullet and made it go.

We're working to build minimal xen-based machines that boot just
enough linux to allow us run Plan 9, and use Linux as nothing more
than a device driver.

Now if I could only get Xen to start.

Anybody had trouble with Xen and logical volumes? My xen kernel built
from source just can't find volume00. This is xen 3.0.3, ia32, SATA,
2.6.16.29-xen. I have done the mkinitrd by hand, but all the right
modules seem to be in there. nevertheless, on this sata machine I
don't see it finding hda as it does with a non-Xen kernel.

If anyone has seen this, let me know.
