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. */
