[Xen-devel] Xen0 crash dump (/dev/ram0 root) possibly of interest
I''m continuing to work on making a new XenCD as previously discussed
here. In
the course of that work, I''ve generated (actually, currently stuck on)
the
enclosed crash dump. Thought I''d forward it for interest.
To head off questions, you''ll see references to a very large initrd
(~114 Mb).
The Xen dump may or not be related to this unusual usage. I''ve
done both
large initrds, small initrds, and small initrds in the past which copy larger
filesystems to tmpfs. I''ve done huge initrds with success before,
outside of
Xen. The numbers below are calculated automatically and should be big enough,
though may not be aligned properly.
Mark Williamson: if you see this, could you forward me a copy of the Xen 1.2
CD you offered to do earlier? I''d like to see to see which initrd
techniques
you used, if any.
My GRUB config looks like:
title xen
kernel /boot/xen dom0_mem=318464 com1=115200,8n1 console=com1,vga
ignorebiostables nmi=ignore sched=bvt conswitch=xy noreboot
module /boot/xen0-vmlinuz ramdisk_size=203776 root=/dev/ram0 max_loop=96 rw
console=ttyS0 vga=extended
module /boot/xen0-initrd
I can provide access to the ISO if anyone cares, though it''s obviously
non-functional currently.

Re: [Xen-devel] Xen0 crash dump (/dev/ram0 root) possibly of interest
Looks to me like it should work -- you have enough contiguous RAM to store the initrd image. I just checked in new heap-initialisation code that takes into account the e820 memory map. I think there may still be a few bugs in it and you may be triggering one. It is worth trying a debug build of Xen and seeing if that gives any more info about the crash. -- Keir> I''m continuing to work on making a new XenCD as previously discussed here.

Re: [Xen-devel] Xen0 crash dump (/dev/ram0 root) possibly of interest

I switched to a fresh xeno-unstable.bk xen, and the crash dump went away. Excellent. It booted right up into an apparently-working initrd and gave me a command prompt after booting off the ISO.

> Mark: thanks, anytime for that CD.I''m actually having trouble finding an original ISO image, though I had one on the HDD. I''ll keep looking but if anyone else has the file, that might speed things up ;-) Mark ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.

> Mark: thanks, anytime for that CD. > > I''m actually having trouble finding an original ISO image...No problem, my mail client did a weird thing and sent out old messages, rather embarassing. Didn''t mean to actually ping you about it :) In any case, lack of the CD hasn''t hindered development of a functional CD. I have a working CD with this architecture: - GRUB boot + menu - xen.gz + xen0 + debian dm0 default boot option - memdisk + memtest86, tomsrtbt, ttylinux boot options - debian dom0 is straight debootstrap unstable, with various bits rm -rf''ed, plus xen-required packages (python-twisted, etc). - pure text-mode apps installed. can apt-get other packages into the ramdisk as needed. - currently implemented as a 25 Mb initrd. Should be able to be netbooted, etc eventually. having problems getting post-pivot_root freeramdisk to release initrd''s memory, so currently just running out of the rw initrd - custom /linuxrc+rcS, autostart xend, xensv - xen.gz + xen0 built from xeno-unstable.bk - 30Mb ISO thus far Planned improvements: - networking (just dhcpc on dom0 now) - media discovery, so it can find and autostart ttylinux + other rootfs''s (/dev/cdrom isn''t mounted currently) - xen-stable/xen-testing builds - more bootprompt configuration of dom0 - use of debian packages for install of xen into dom0 (uses cp -a now) It''d be easier for me to put on contributed rootfs''es rather than me working on finely tuned fedora/gentoo/whatever examples xenU instances. I''m intending to use the same codebase for my server installs, but no reason not to combine both efforts. So if there are rootfs maintainers who''d think it''d be neat to have their xenU rootfs on a demo cd, let me know (here or offline). Sorry for announcing all this without releasing any URLs yet. I''m about to go on a week-long away-from-keyboard vacation, so it''ll be a few weeks yet before I''ll be able to provide a URL for people to download the first release. ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
