[Xen-devel] Domain0 won''t boot on latest unstable bits?
I just bk-clone''d the latest unstable, rebuilt everything
(including using the new ''make ARCH=xeno'' syntax*** for
building xenolinux) and on boot, I got:
DOM0: Unable to obtain IOPL, despite being SIF_PRIVILEGED
Just to make sure, I repeated everything and still got
the same result. (I know... that''s the definition of
insanity ;-)
Maybe I got bits in the middle of somebody''s checkin?
It''s getting late on Friday here so I will try it again
next week, but wanted to report it in case there is a
bigger problem.
*** By the way, the new syntax is inconsistent with
2.6 linux builds so this new requirement may
generate a lot of confusion. Xen uses
make ARCH=xxx
and Linux 2.6 uses
ARCH=xxx make
and they are definitely different. I''m no make
expert and this may be unrelated but doing
make ARCH=xeno oldconfig dep bzImage
doesn''t work for me unless I do the steps
with separate make''s.

Are you sure you are building both, that XL is taking teh correct hypervisor-ifs header files; and that you are booting the two most recent built images?> *** By the way, the new syntax is inconsistent with > 2.6 linux builds so this new requirement may > generate a lot of confusion.

The syntax ''ARCH=xeno make xxxx'' will work again now. You should find that ''ARCH=xeno make mrproper oldconfig dep bzImage'' does the right thing... -- Keir ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

For now I''d recommend doing each step individually: ARCH=xeno make mrproper ARCH=xeno make oldconfig ARCH=xeno make dep ARCH=xeno make bzImage -- Keir ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

I didn''t notice that the interface had changed in the week or two since I last grabbed unstable, so hadn''t bothered to copy over a new xen.gz.

For now I''d > recommend doing each step individually: > ....I''ve further investigated the problem that I was seeing, and I conclude that it is present in non-Xen Linux as well (e.g., native i386). This works: ARCH=xeno make mrproper oldconfig dep bzImage ...and this works: ARCH=xeno make mrproper ARCH=xeno make oldconfig ARCH=xeno make dep ARCH=xeno make bzImage ...but this DOESN''T work: ARCH=xeno make mrproper ARCH=xeno make oldconfig dep ARCH=xeno make bzImage (make[2]: *** No rule to make target `/linux-2.4.25/include/linux/modversions.h'', needed by `sched.o''. Stop.) I have no explanation for this behaviour -- reading the manual for make I would expect all three to work correctly. If you exclude the ''ARCH=xeno'' from each line (i.e., build native x86 Linux) then the problem still appears! At least it''s not a bug that we''ve created. :-D -- Keir ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
