As of now (2024-22-05) Xen with stubdom doesn't build because of a problem in the imported code. Been this way for about two weeks. Anyone else seeing this behavior?

Also, there is a lot of work happening on Xen in my development repo, thanks to @Serus. Check it out at: https://github.com/refutationalist/saur

No problem getting Xen 4.13.0 compiled and running. Had to change one configure option...

linuxninja commented on 2020-05-05 16:35 (UTC)

Any updates on getting the version moved up? This package is now a couple of versions behind upstream... current Xen version is 4.13.0

I was able to get 4.12.2 to build without issue.

Upgraded to the latest kernel, 5.6.10, and it broke networking for Xen HVM (opnsense). Downgraded the kernel back to 5.5.8 and things work, again. Not sure which kernel version is the last one that works since I haven't upgraded each release.

Not sure if we not need to install the xen /boot/xen-$version.config, we do not have a Arch linux /boot/config-vmlinuz, which is where one GRUB 20_linux_xen issue comes from: GRUB upstream bug: 20_linux_xen does not work if no kernel config file

xen-$version.efi may still be wanted by some, and GRUB should not add this as a multiboot2 option: GRUB upstream bug: 20_linux_xen also creates garbage entries for xenconfig and xenefi

Xen installs the /usr/lib/modules-load.d/xen.conf file. It also contains (historic) module names that do not exist in our distribution. systemd-modules-load.service will exit with failure for these nonexistant modules, but boot does continue. see:pacman -Ql linux | grep -E 'xen-' https://aur.archlinux.org/pkgbase/xen/?O=0&PP=100#comment-622244

Ah, thanks.

My second GRUB patch null config filename we could workaround by installing: /boot/config-${linux pkgbase} with CONFIG_XEN_DOM0=y in a pacman hook? But this is only appropriate to booting Xen with GRUB on Arch. I will open bug upstream and pursue it there as well.

Thanks! Please post a link when you do :)

Hey FF,

Great to see progress.

modules-load.d/xen.conf

Xen installs the /usr/lib/modules-load.d/xen.conf file. It also contains (historic) module names that do not exist in our distribution. systemd-modules-load.service will exit with failure for these nonexistant modules, but boot does continue. see:pacman -Ql linux | grep -E 'xen-' https://aur.archlinux.org/pkgbase/xen/?O=0&PP=100#comment-622244

GRUB helper fixes upstream

Yes, will try for GRUB helper upstream changes.

Should not need my first GRUB patch -vmlinuz-*, +vmlinuz anymore, as it looks like mkinitcpio installs kernel as vmlinuz-${pkgbase} now I use dracut, so I cannot check this on system. https://git.archlinux.org/mkinitcpio.git/tree/libalpm/scripts/mkinitcpio-install

My second GRUB patch null config filename we could workaround by installing: /boot/config-${linux pkgbase} with CONFIG_XEN_DOM0=y in a pacman hook? But this is only appropriate to booting Xen with GRUB on Arch I will open bug upstream and pursue it there as well.

Cheers

I think we should work on fixing the issue in the upstream (so, grub) and backport the patch to the grub package. Do you want to do it? Since you wrote the patches.

The two last patches that is. For the first we should open a bug report for grub package.

FFY00 commented on 2020-04-04 17:08 (UTC)

Hey, sorry for the delay catching up.

ovmf typo in your PKGBUILD optdepends and Xen configure option Package has /etc/init.d/ files

Fixed (locally).

Maybe some sort of install message about: - booting Xen & enabling services? (Xen gets booted before linux dom0) - fixing dom0 memory in the bootloader Xen hypervisor config

Will add before moving to the repos.

Worth cleanup of usr/lib/modules-load.d/xen.conf to avoid modules load errors: I used this in prepare(). find tools -iname 'configure*' -exec sed -i -E -e '/^LINUX_BACKEND_MODULES="$/,/^"$/{/"/b;/^xen-/!d;s/scsibk/scsiback/;};' {} \;

Can you explain exactly what is the issue here?

GRUB helper for loading the Xen dom0: It might be better to fix the Arch grub package with a patch so that 20_linux_xen works for arch kernel? My old changes linked. Need retesting. - vmlinuz- - don't fail on no /boot/config file - ignore xen files grub cannot boot

I think we should work on fixing the issue in the upstream (so, grub) and backport the patch to the grub package.

Do you want to do it? Since you wrote the patches.

Hey FF,

Have not yet had a chance to install and test, but looking over it again:

Cheers
