[bug #46014] XEN domU crash when PV grub chainloads 32-bit domU grub

Follow-up Comment #11, bug #46014 (project grub): Much better, thank you. I took commit bcf3c55531349dfec135cad9bf359960214dd0f6 and applied it on top of the version mentioned in comment #9. The resulting dom0 image is now able to chainload the guest kernel as desired. I also cherrypicked the

Follow-up Comment #9, bug #46014 (project grub): Tested git master at 529818738fb2aafb05721830dc99cc6c8736a048. Same outcome as before, i.e. chainloading fails, configfile fallback succeeds. (I expected this as the Debian patches seemed orthogonal to this issue, but of course it's better to

Follow-up Comment #7, bug #46014 (project grub): I downloaded grub-2.02~rc1.tar.xz, debianized it based on grub2_2.02~beta3-4.debian.tar.xz (two patches dropped as they are included in rc1), and applied commit 8a96fc409373fffda99e18a8438ddfc6bb787bc8 on top of it all. I did not include the "xen:

Follow-up Comment #6, bug #46014 (project grub): Did you take branch or applied patch from ML (not from branch) ? Are both GRUBs updated? Does git master work? What is xen version? Is host 32 or 64-bit? I CNR on master. Can you send your binaries?

Follow-up Comment #5, bug #46014 (project grub): I regret to report that the patch referred to by comment #3, when applied by itself on top of 2.02-rc1, doesn't fix this bug for me. I went to some length to purge previous versions of GRUB from the PV guest, in an attempt to avoid further red

Follow-up Comment #4, bug #46014 (project grub): Yes, my comment #2 was wrong. On closer examination the change simply causes pvboot-i386.elf to fail and the dom0 to fall back to searching for grub.cfg directly. Sorry for the noise. Will try your patch.

Follow-up Comment #3, bug #46014 (project grub): I believe this is red herring. Please try the patch that I've posted on grub-devel mailing list (https://lists.gnu.org/archive/html/grub-devel/2017-02/msg00031.html) or the branch xenfixes

Follow-up Comment #2, bug #46014 (project grub): I think I've found a solution. If I change Xen ELF note 9 (PAE_MODEL) from the current "yes" to "no", the resulting image boots successfully all the way into Linux (i686-pae). The attached patch should take care of this problem, and also of #50237
