Not sure what I should do here, after doing a routine update where I took Linux 5.0.5 and systemd 241.67-1 I started getting a lot of dmesg spam after a reboot.
The core of the issue was the following:
Linux version 5.0.5-arch1-1-ARCH (builduser@heftig-17705) (gcc version 8.2.1 20181127 (GCC)) #1 SMP PREEMPT Wed Mar 27 17:53:10 UTC 2019

[ 10.493334] kvm: Nested Virtualization enabledI resolved the issue by first rolling back my Linux package to 5.0.4 and then rolled back systemd to 241.7-2
Is this something one should post a bug to Arch, or should this go upstream?
Update: I moved forward to linux 5.0.5 and the error hasn't happened again, so I'm guessing the issue lies with systemd.

Does the issue only occur when using qemu?
Can you bisect between systemd 241.7-2 and systemd 241.67-1 to find the causal commit?

Issue happens at boot before I even can login — or pretty much simultaneously with the login prompt.
Not sure how I can bisect the systemd package, is there a good guide out there?
I ask because I reverted three different packages associated with systemd, and i’m not sure if I can roll one forward at a time to see which one breaks it, or if it’s an all or nothing kind of change that has to happen.

The following assumes the base-devel group and git are installed.
$ git clone git://git.archlinux.org/svntogit/packages.git --single-branch --branch "packages/systemd"
$ cp -r packages/trunk systemd
$ rm -rf packages
$ cd systemd
$ makepkg -rsi #this is to confirm systemd as built on your system has the issue
$ cd systemd/src/systemd-stable
$ git bisect start
$ git bisect bad
$ git reset --hard
$ git checkout cbf14c9500d5e6820fd7d96166ca0bf75c6850df
$ git apply ../../0001-Use-Arch-Linux-device-access-groups.patch
$ rm -rf ../build
$ cd ../..
$ makepkg -ersi #this is to confirm systemd 241.7 as built on your system does not have the issue
$ cd systemd/src/systemd-stable
$ git reset --hard
$ git bisect good
$ rm -rf ../build
$ cd ../..
$ makepkg -ersi #test the bisection point
$ cd systemd/src/systemd
$ git reset --hard
$ git bisect $result #substitute good or bad here
$ git apply ../../0001-Use-Arch-Linux-device-access-groups.patch
$ rm -rf ../build
$ cd ../..
$ makepkg -ersi #repeat these ten lines and test the generated package until git has found the bad commitSee also Bisecting_bugs_with_Git
Edit:
fixup instructions add missing cd systemd, missing git reset --hard and correct build directory location.

Hmm, ran into an issue:
