We've moved to the newly-stable 4.20.0 branch. There are also other changes:

  • stubdom is fixed by disabling the vtmp and vtpmmgr components. This gets rid of a few source files and our remaining patches.
  • Debug files are only removed if the debug option is not set in makepkg.cfg (or the PKGBUILD itself)
  • pygrub has been removed
  • optdepends are adjusted for the upcoming xen-grub split package for the various Xen flavored builds.

If you're still using pygrub note that it is deprecated. The solution is to build PV grub instead, which used to be in AUR but is now missing. I am asking a couple questions on the mailing list, and I intend to put my current build of xen-grub (which supersedes xen-pvhgrub) on AUR as soon as possible. If you need to build it before that occurs, you can find it in my PKGBUILD repo.

EDIT: 4.20.0-2 adds support for the xen-edk2 package, which has a fixed UEFI for xen

Please replace the dependency sdl with sdl2 in your next version. SDL v1.2 is outdated and, as far as I can tell, is no longer supported by xen-4.14. Additionally libjpeg-turbo will be needed.

For the record, I almost universally use linux-lts on my servers, and that continues to work.

Also, when you update EFI, remember to copy the EFI kernel to /boot. That's not for you, that's for me, since I just spent an hour forgetting that.

EDIT: I will add a reminder in the next update. Maybe consider a hook, see how the kernels do it.

Updated to 4.14.0-4, added security patches, cmake fixes from cdchapman for stubdom building.

@alaricljs: that info would be better documented in the Wiki's Discussion page (or an update to the wiki if you have a procedure tested). Comments get lost into oblivion.

A partial (dom0 & PV) solution to the zstd compression issue that sticks to current kernels: https://gist.github.com/alaricljs/757d4b452335b187d7dff1b7e2c5808e

A Pacman hook that grabs the uncompressed kernel and puts it in /boot. Works on dom0 and PV guests (that's all that was tested, perhaps others work too).

Thanks to the previous comments I installed linux-lts and then sudo grub-mkconfig -o /boot/grub/grub.cfg it worked :) A new entry appeared on GRUB menu and now I booted to dom0 successfully.

Thank you for your tip @g8sqh!!!

I've posted this issue on forums some days ago (https://bbs.archlinux.org/viewtopic.php?id=260107), following the guidelines not to post questions etc here), but nobody answered.. ¬_¬

g8sqh commented on 2020-10-23 11:00 (UTC)

Please also note that Xen (4.14.0) no longer works with the standard Arch kernel (at least as dom-0)

Arch (at 5.9.1) compresses using zstd (CONFIG_KERNEL_ZSTD=1), and the ELF-reading code in Xen has a decompressor for xz (in xen/common/xz), but nothing for zstd

Message is elf-init: not an ELF binary and a (xen) kernel panic.

Until either Xen gains zstd, or Arch provides a kernel package using xz, you need an older kernel from the archive, or to build from source with CONFIG_KERNEL_XZ=1

Gotcha @eduncan911. Link: https://bbs.archlinux.org/viewtopic.php?id=259428

Everyone, please take this to the forums. Subscriptions to package notifications are just that: notifications about package updates, breaks, and news.

It's not a discussion, debugging, nor How To forum.
