nixpkgs/pkgs/build-support/vm/default.nix
Eelco Dolstra 03f51200c2 * A function `runInGenericVM' that performs a build in an arbitrary VM
image (i.e., it can contain any OS that obeys the interface
  documented in the comment).  See `testFreeBSD' for an example that
  performs a build of the ATerm library on FreeBSD 7.0.  This will be
  used in the build farm to perform builds for platforms for which we
  cannot synthesize VM images automatically.

/* Run a derivation in a Linux virtual machine (using Qemu/KVM). By
default, there is no disk image; the root filesystem is a tmpfs,
and /nix/store is shared with the host (via the CIFS protocol to
a Samba instance automatically started by Qemu). Thus, any pure
Nix derivation should run unmodified, e.g. the call
runInLinuxVM patchelf
will build the derivation `patchelf' inside a VM. The attribute
`preVM' can optionally contain a shell command to be evaluated
*before* the VM is started (i.e., on the host). The attribute
`memSize' specifies the memory size of the VM in megabytes,
defaulting to 256. The attribute `diskImage' can optionally
specify a file system image to be attached to /dev/sda. (Note
that currently we expect the image to contain a filesystem, not a
full disk image with a partition table etc.)
If the build fails and Nix is run with the `-K' option, a script
`run-vm' will be left behind in the temporary build directory
that allows you to boot into the VM and debug it interactively. */
