I'm not quite sure why the official Hydra gets a kernel panic in one of
two VMs using the exact same kernels:
https://hydra.nixos.org/build/26339384
Because the kernel panic happens before stage 1, let's wait for the
first VM to boot up and after the bootup is done, start the second one
in hope that it won't trigger the panic.
Oddly enough, whenever I run the test on my own Hydra and on my local
machines, I don't get anything like that.

I forgot to do this in da0e642. It shouldn't be a big problem but it's
more clean to destroy the VM once we're done testing.

We previously had 1024 MB of memory to fit a VirtualBox VM with 512 MB
plus the memory needed of the VirtualBox host VM. That obviously won't
work for two VirtualBox VMs, which are used for testing networking
between two VirtualBox guests.
Now, we have 2048 MB on the qemu guest (the VirtualBox host) and 768 MB
for each VirtualBox guest. That should be enough to fit in two
VirtualBox guests (I hope).

Unfortunately, we can't test whether USB is really working, but we can
make sure that VirtualBox has access to the USB devices.
This is essentially testing #9736, which I haven't yet been able to
reproduce though, but it makes sense to test it so it won't happen in
future releases.

Addresses #9876 in the way that we want to make sure that VirtualBox 5.x
is going to be properly detected. Right now the result is "kvm", so the
subtest fails as expected with:
error: systemd-detect-virt returned "kvm" instead of "oracle" at (eval
14) line 414, <__ANONIO__> line 92.

We're simply using antiquotation, since it's been a while since these
got introduced (in Nix 1.7). So we can use them because it makes the
code much more readable.
As usual, I made sure that I didn't accidentally change something in
functionality:
$ nix-instantiate nixos/tests/virtualbox.nix
...
/nix/store/cldxyrxqvwpqm02cd3lvknnmj4qmblyn-vm-test-run-virtualbox.drv
$ git stash pop
...

This is essentially not only "wrapping" the line but refactoring into a
shorter name which is used in two places.
And yes, I know I'm very pedantic if it comes to whitespaces and line
lengths, but I made sure this doesn't change any functionality:
$ nix-instantiate nixos/tests/virtualbox.nix
...
/nix/store/cldxyrxqvwpqm02cd3lvknnmj4qmblyn-vm-test-run-virtualbox.drv
$ git stash pop

Instead of manually setting debug to true or false, this should make it
possible to now run the test like this:
nix-build nixos/tests/virtualbox.nix --arg debug true

Sometimes there are random kernel panics do to the lack of memory in the
qemu guests, but as we're setting the VirtualBox memory size relatively
low, 1024 MB should be enough for the qemu guests.

We want to check whether DBus functionality is working, so let's make
sure it is running in our mini-initrd.
DBus unfortunately requires to have users properly set up and another
configuration file other than in ${dbus.daemon}/etc/dbus-1/system.conf,
so we do provide that as well.

Commit 687caeb renamed services.virtualboxHost to programs.virtualbox,
but according to the discussion on the commit, it's probably a better to
put it into virtualisation.virtualbox instead.

Using $storepath/sbin is deprecated according to commit 98cedb3, so
let's avoid putting anything in .../sbin for the guest additions.
This is a continuation of the initial commit done by @ctheune at
1fb1360, which unfortunately broke VM tests and only changed the path of
the mount.vboxsf helper.
With this commit, the VM test is fixed and I've also verified on my
machine that it is indeed working again.

Sometimes, keys aren't properly recognized the first time, so in order
to make sure they get through, always resend the key again on retry.
In this case the worst that could happen is that the VM is started over
and over again, but never in parallel, so that's fine because we're
checking for successful startup 10 seconds after the keypress.

Especially if the user isn't in the vboxusers group anymore, this gets
VERY noisy, because the VBoxSVC process emits warnings for every single
USB device noting that it's only possible to access it when the user is
in the vboxusers group.
So, we now have a debug attribute, where we can enable it when
necessary.

really don't need. Except the log, but therefore we now cat the log to

Essentially adds two more VirtualBox VMs to the test and also increases
the memory size of the qemu VM to 768 MB to make sure we don't run out
of memory too soon.
We're testing whether those two VMs can talk to either each other
(currently via ICMP only) or to/from the host via TCP/IP.
Also, this restructures the VM test a bit, so that we now pass in a
custom stage2Init script that has access to the store via a private
mount over the /nix/store that's already in the initrd. The reason why
this is a private mount is that we don't want to shadow the Nix store of
the initrd, essentially breaking cleanup functionality after the custom
stage 2 script (currently this is only "poweroff -f").
Note that setting the hostname inside the VirtualBox VM is *not* for
additional fanciness but to produce a different store path for the VM
image, so that VirtualBox doesn't bail out when trying to use an image
which is already attached to another VM.

We're going to create more than one VirtualBox VM, so let's dynamically

Currently it pretty much tests starting up virtual machines and just
shutting down afterwards, but for both VBoxManage and the VirtualBox
GUI.
This helps catching errors in hardened mode, however we still need to
test whether networking works the way intended (and I fear that this is
broken at the moment).
The VirtualBox VM is _not_ using hardware virtualization support (thus
we use system = "i686-linux", because x86_64 has no emulation support),
because we're already within a qemu VM, which means it's going to be
slow as hell (that's why I've written own subs just for testing
startup/shutdown/whatnot with respective timeouts).
