This adds a new function in vmTools, called runInWindowsVM, which allows
to run a derivation within a Windows + Cygwin environment.
To use it, you need to pass a Windows ISO and product key, for example:
------------------------------------------------------
vmTools.runInWindowsVM (stdenv.mkDerivation {
name = "hello-from-windows";
windowsImage = {
isoFile = /path/to/windows/image.iso;
productKey = "ABCDE-FGHIJ-KLMNO-PQRST-UVWXY";
};
buildCommand = ''
echo 'Look, I am running inside Windoze!'
uname -a > "$out"
'';
})
------------------------------------------------------
The derivation is then run within a special build process, which roughly
does something like this:
____________
| |
| controller |
|____________|
/ | \
_________ / ____|____ \___________ _______
| | | | | | | |
| install | -> | suspend | -> | suspended | -> | build |
|_________| |_________| |___________| |_______|
There are three steps necessary to produce the builder, which in the end
is just a suspended Windows VM, running Cygwin and OpenSSH.
Those steps are essentially:
* install: Install the base Windows VM with Cygwin and OpenSSH.
* suspend: Run the installed VM and dump the memory into a state file.
* suspended: Resume from the state file and execute the build.
Every build is based on the "suspended" step, which throws away all
changes except to the resulting output store path(s).
All of these steps are based on the controller, which is described in
greater detail in commit
