I noticed some interesting improvements to Mini-OS announced on this
list, so I thought I''d try them out. Before looking at the new
features, I ran into a problem starting a Mini-OS domain.
I''ve just performed a fresh install of Fedora Core 6, and installed
xen, kernel-xen, and virt-manager, and booted up xen. Next I pulled
the latest version of xen-unstable.hg, cd''d into extra/mini-os, and
successfully made mini-os.elf. When I attempt to start the kernel, xm
claimed the kernel did not exist!

So you might think that os.path.isfile is broken. Not so.

I must be doing something silly. If not, should I send this bug

In kernel.c (miniOs)
Move:
/* ENABLE EVENT DELIVERY. This is disabled at start of day. */

After:
