nixos/test-driver: Use guest time when using sleep
With the Perl driver, machine.sleep(N) was doing a sleep on the guest
machine instead of the host machine. The new Python test driver however
uses time.sleep(), which instead sleeps on the host.

While this shouldn't make a difference most of the time, it *does*
however make a huge difference if the test machine is loaded and you're
sleeping for a minimum duration of eg. an animation.

I stumbled on this while porting most of all my tests to the new Python
test driver and particularily my video game tests failed on a fairly
loaded machine, whereas they don't with the Perl test driver.

Switching the sleep() method to sleep on the guest instead of the host
fixes this.

Florian Klink 0620184f3f nixos/lib/test*: remove perl test driver
This has been deprecated in 20.03, and all tests have been migrated to
the python framework, effectively making this dead code.

Matthew Bauer 47b56e7c19 runInLinuxVM, test-driver: use -cpu max instead of -cpu host
This appears to avoid requiring KVM when it’s not available. This is
what I originally though -cpu host did. Unfortunately not much
documentation available from the QEMU side on this, but this appears
to square with help:

$ qemu-system-x86 -cpu help
...
x86 host                  KVM processor with all supported host features
x86 max                   Enables all features supported by the accelerator in the current host
...

Whether we actually want to support this not clear, since this only
happens when your CPU doesn’t have full KVM support. Some Nix builders
are lying about kvm support though. Things aren’t too slow without it
though.

Fixes https://github.com/NixOS/nixpkgs/issues/85394

nixos/manual: improve error message for invalid values in `relatedPackages'
As reported in NixOS discourse[1], tracking down invalid values in
`relatedPackages'[2] (i.e. list-items that don't exist in `pkgs`) is
fairly hard as the message "Invalid package attribute path `foobar'"
is quite unhelpful and the trace doesn't point to the source of the
problem either.

This patch improves the error message by mentioning that the issue is an
invalid `relatedPackages`-declaration in $optionName.

Julian Stecklina fd2047c642 nixos/lib/make-ext4-fs: fix after mkfs.ext4 refactoring
In 9ac1ab10c9 this library function was
refactored to use mkfs.ext4 instead of cptofs. There are two problems:

If populateImageCommands would create no files (which is fine), a cp
invocation would fail due to missing source arguments.

Another problem is that mkfs.ext4 relies on fakeroot to have sane
uid/gids in the generated filesystem image. This currently doesn't
work for cross compiling.

`services.dhcpd4.machines` option.

and exported from `qemu-flags.nix`.

make-iso9660-image: produce stable GPT disk GUID
By generating a version-5 GUID based on $out (which contains
the derivation hash) and preventing isohybrid from overwriting
the GPT table (which already is populated correctly by xorriso).

Tested by:
* booting from USB disk on a UEFI system
* booting from USB disk on a non-UEFI system
* booting from CD on a UEFI system
* booting from CD on a non-UEFI system
* booting from CD on an OSX system

Also tested that "nix-build ./nixos/release-combined.nix -A
nixos.iso_minimal.x86_64-linux -I nixpkgs=~/nixpkgs-r13y --check"
now succeeds.

Fixes #74047

test-driver.py: delete VM state directory after test run
Keeping the VM state test across several run sometimes lead to subtle
and hard to spot errors in practice. We delete the VM state which
contains (among other things) the qcow volume.

We also introduce a -K (--keep-vm-state) flag making VM state to
persist after the test run. This flag makes test-driver.py to match
its previous behaviour.

Florian Klink 079de14fd3 nixos/make-ext4-fs: increase fudge factor from 1.03 to 1.10
Turns out, on smaller images (~800MiB uncompressed sdcard image size),
the current fudge factor is way too small to even get the system to the
phase where it can resize itself.

I first tried with 1.05, but it wasn't enough.

qemu-vm: fix inconsistent caching of xchg dirs
xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.

9p doesn't provide any suitable cache modes, so fix this by disabling
caching.

Also, remove a now unnecessary sync in the test driver.

test-driver: remove useless syncs
These syncs have the goal to transfer host filesystem changes to the VM,
but they have no effect because 1) syncing in the VM can't possibly pull
in host data and 2) 9p is accessing the host filesystem on the cached
layer anyways, so even syncing on the host would have no effect in the
VM.

Eelco Dolstra 78f2a83029 test-driver.py: Fix deadlock when the log queue gets full
If a program (e.g. nixos-install) writes more than 1000 lines to
stderr during execute(), then process_serial_output() deadlocks
waiting for the queue to be processed. So use an unbounded queue
instead.

We should probably get rid of the structured log output (log.xml),
since then we don't need the log queue anymore.
