Hello xen-users,
http://git.savannah.gnu.org/cgit/grub.git/
I'm doing a build of latest grub-2.05 with the goal of making the
pvgrub2 images for x86_64-xen and i386-xen_pvh. These can be used to
boot domU VM in a variety of ways: from root symlinks, grub legacy
configs, or grub2 configs especially for pv and pvh types.
Pvgrub2 images from Buster:
grub-i386-qemu.bin
grub-i386-xen.bin
grub-i386-xen_pvh.bin
grub-x86_64-xen.bin
The images made in C8 worked as desired and gave useful output. The
Buster images failed silently. The C8 had build had hardening
undefined, so I tried that in Buster with no help.
What got success with Buster was noticing that the xen devel headers
were not the same with C8.
// headers in Buster
pbdeps$ sudo ls -al /usr/include/xen/
total 36

//headers in C8
(all same)

Owners of gntdev.h
// gntdev.h owner on C8
mockbuild@c80pv:~$ sudo rpm -qf /usr/include/xen/gntdev.h
kernel-headers-4.18.0-147.5.1.el8_1.x86_64
// owner on Buster
/pbdeps$ sudo dpkg -S /usr/include/xen/gntdev.h
linux-libc-dev:amd64: /usr/include/xen/gntdev.h
Since 2 years ago I was told that the Xen headers were already
installed with the OS and there is no need to install any supporting
xen-devel package.
Swapping in the C8 gntdev.h was a desperate move, but it got the job done.
What else could I do to avoid a bad gntdev.h in Buster?
cheers,
