I've started digging into the actual cause of the problem a week ago but
didn't continue fixing this.
The reason why the tests are failing is because
torvalds/linux/commit/72f5e08dbba2d01aa90b592cf76c378ea233b00b has
remapped the location of the TSS into the CPU entry area and we did
update our default kernel to version 4.14 in NixOS/nixpkgs@88530e02b6.
Back to VirtualBox: The guru meditation happens in
selmRCGuestTssPostWriteCheck, which I think is only a followup error. I
believe the right location couldn't be determined by VirtualBox and thus
the write check function triggers that panic because it's reading from
the wrong location.
So the actual problem *only* surfaces whenever we use software
virtualization, which we do for our tests because we don't have nested
virtualization available.
Our tests are also for testing the functionality of VirtualBox itself
and not certain kernel versions or kernel features, so for the time
being and until this is fixed, let's actually use kernel version 4.9 for
the guests within the VM tests. Kernel 4.9 didn't have the mentioned
change of the TSS location and thus the tests succeed.

Updated to the latest version of the nixos-v237 branch, which fixes two
things:
* Make sure that systemd looks in /etc for configuration files.
https://github.com/NixOS/systemd/pull/15
* Fix handling of the x-initrd.mount option.
https://github.com/NixOS/systemd/pull/16
I've added NixOS VM tests for both to ensure we won't run into
regressions. The newly added systemd test only tests for that and is by
no means exhaustive, but it's a start.
Personally I only wanted to fix the former issue, because that's the one
I've been debugging. After sending in a pull request for our systemd
fork (https://github.com/NixOS/systemd/pull/17) I got a notice from
@Mic92, that he already fixed this and his fix was even better as it's
even suitable for upstream (so we hopefully can drop that patch
someday).
The reason why the second one came in was simply because it has been
merged before the former, but I thought it would be a good idea to have
tests for that as well.
In addition I've removed the sysconfdir=$out/etc entry to make sure the
default (/etc) is used. Installing is still done to $out, because those
directories that were previously into sysconfdir now get into
factoryconfdir.
Quote from commit NixOS/systemd@98067cc806:
By default systemd should read all its configuration from /etc.
Therefore we rely on -Dsysconfdir=/etc in meson as default value.
Unfortunately this would also lead to installation of systemd's own
configuration files to `/etc` whereas we are limited to /nix/store. To
counter that this commit introduces two new configuration variables
`factoryconfdir` and `factorypkgconfdir` to install systemd's own
configuration into nix store again, while having executables looking
up files in /etc.
Tested this change against all of the NixOS VM tests we have in
nixos/release.nix. Between this change and its parent no new tests were
failing (although a lot of them were flaky).

Fixes: #35415Fixes: #35268
All 5 daemon types can be enabled and configured through the module and the module both creates the ceph.conf required but also creates and enables specific services for each daemon, based on the systemd service files that upstream provides.
Use systemd to create the directory for UNIX socket. Also use localhost instead
of 127.0.0.1 as is done in default cupsd.conf so that IPv6 is enabled when
available.
