* 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 command in a x86 virtual machine image containing an
arbitrary OS. The VM should be configured to do the following:
- Write log output to the serial port.
- Mount //10.0.2.4/qemu via SMB.
- Execute the command "cmd" on the SMB share. It can access the
original derivation attributes in "saved-env" on the share.
- Produce output under "out" on the SMB share.
- Write an exit code to "in-vm-exit" on the SMB share ("0"
meaning success).
- Reboot to shutdown the machine (because Qemu doesn't seem
capable of a APM/ACPI VM shutdown).
