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.. ¬_¬
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.
@skyzh Sorry for the flurry of comments; How do you actually apply that patch? I've done makepkg -o to just get the source files, I haven't done much manual makepkg work before.

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