-You will need a cross-compilation toolchain, for example, `aarch64-linux-gnu`, which can be installed with `apt-get` using the following command-line:

-Makefiles use the `CROSS_COMPILE` variable to specify the prefix of the tools; in the case above it is `aarch64-linux-gnu-` (note the trailing dash). In the examples that follow, we will assume that this toolchain is installed and available for use.

 ### Format of `vms.txt` file
 The format is currently one line per secondary VM, with the following format:

 ``` shell

-For example, the following defines two secondary VMs, the first one with 1MB of memory, 2 CPUs and kernel image called `kernel0`, while the second one has 2MB of memory, 4 CPUs and a kernel image called  `kernel1`.
