virtualbox and ubuntu linaro toolchain to build xen-unstable smmu-v9

I finally got virtualbox configured the way I liked.

I had to log in to the VM to do this:

apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

After install, I rebooted the Ubuntu 14.04 guest and the screen resolution works fine.

To build xen-unstable in Julien's xenbits tree, I did the following:

0. pull the smmu-v9 branch like so:
git clone git://xenbits.xen.org/people/julieng/xen-unstable.git

git pull smmu-v9

1. install tool chain

thomas@thomas-VirtualBox:~/projects/xen-unstable$ sudo apt-get install gcc-aarch64-linux-gnu




Then I can compile:

make xen XEN_TARGET_ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
