Hi Nicolas,

I believe you need more recent versions of mirage, mirage-xen and tcpip than those that are currently available in opam.

Take a look at Thomas Leonard's blog post here: http://openmirage.org/blog/introducing-xen-minios-arm - in particular the 'opam pin' commands.

Good luck!

Dear list,

Recently I came into possession of a Cubieboard 2 (Thanks Anil!) and set out to

install Xen/Mirage guided by the following sets of instructions:

[1]: https://github.com/mirage/xen-arm-builder

[2]: http://openmirage.org/wiki/install

[3]: http://openmirage.org/wiki/hello-world

TL;DR: The link to the pre-built binaries in [1] is broken, but building from

source I was able to successfully install mirage on the Cubieboard and run the

UNIX version of the Hello, World! unikernel. ÂHowever, the Xen version did not

work because the opam package mirage-xen 1.1.1 did not compile (some command

line options were not recognized by cc). ÂThe full build log is at

<https://gist.github.com/nojb/b7972e42e317160771c5>.

It seems that this problem should be quite easy to solve by someone more

knowledgeable than me.

I am also sharing the exact steps I took to set up the Cubieboard in case they

are of use to someone else.

Best wishes,

Nicolas

How to install Xen/Mirage on a Cubieboard 2

-------------------------------------------

This is a record of what I had to do to install Xen on a Cubieboard 2. ÂI am

sending it to the list in case it is of use to someone else.

Before we start, ingredients:

Â Â Â Â - MacBook Pro, Early 2011, OS X 10.9.4, 8GB RAM.

Â Â

Â Â Â Â - Cubieboard 2.

Â Â Â Â Â See pic here: http://s28.postimg.org/xdou7ajvx/image.jpg

So, let's get started.

Step 1: Go to https://github.com/mirage/xen-arm-builder.

Â Â Â Â Click on the link that advertises a pre-built binary for the cubieboard2

Â Â Â Â and realize that it is not working. ÂWe have to build from source.

Step 2: Get VirtualBox for OS X from https://www.virtualbox.org (Downloads >

Â Â Â Â VirtualBox 4.3.16 for OS X hosts). Run the provided installer.

Step 3: Get Ubuntu Server 14.04.1 LTS from www.ubuntu.com/download/server.

Â Â Â Â Save the image ubuntu-14.04.1-server-amd64.iso somewhere where you can

Â Â Â Â find it.

Step 4: In VirtualBox, create a new vm (OS Type: Ubuntu 64-bit).

Â Â Â Â I assigned 2GB RAM (out of a total of 8GB) and 8GB Hard drive (this

Â Â Â Â turned out to be extremely tight to build xen-arm-builder, so I

Â Â Â Â recommend making it at least 9GB to give yourself some more room).

Â Â Â ÂÂ

Â Â Â Â When prompted for an installation CD, locate the ISO file that you

Â Â Â Â downloaded in Step 3.

Step 5: Follow the prompts and install Ubuntu.

Â Â Â Â Make sure to install sshd when prompted (we want to avoid having to use

Â Â Â Â the VirtualBox UI at all costs).

Step 6: (Optional?) Fix the Wi-Fi in VirtualBox.

Â Â Â Â For some reason the network speeds in VirtualBox would start up ok and

Â Â Â Â then suddendly slow down to a crawl. ÂAfter some googling and some blind

Â Â Â Â guessing I could solve it for my setup.

Â Â Â Â Simply go to Settings > Network and change the drop-down menu 'Attached

Â Â Â Â to:' from 'NAT' to 'en1: Wi-Fi (AirPort)'. Click OK and restart the VM.

Â Â Â Â Log in and type 'ifconfig'. Note the 'inet addr' of the 'eth0' interface.

Step 7: SSH into the VM from your normal (OS X) terminal.

Â Â Â Â Open a terminal and type 'ssh <user>@<ip>' where <ip> is the address

Â Â Â Â from the previous step. Log in.

Step 8: Install git and clone xen-arm-builder from github.

Â Â Â Â sudo apt-get install git

Â Â Â Â git clone https://github.com/mirage/xen-arm-builder

Â Â Â Â cd xen-arm-builder

Step 9: Follow the instructions in the xen-arm-builder README.

Â Â Â Â export BOARD=cubieboard2

Â Â Â Â make clone

Â Â Â Â make build

Â Â Â Â make cubieboard2.img

Â Â Â Â # Exit the ssh session

Â Â Â Â exit

Â Â Â Â # Get the cubieboard2.img file over to the OS X side

Â Â Â Â scp <user>@<ip>:xen-arm-builder/cubieboard2.img .

Â Â Â Â # Insert SDcard into your computer and copy the .img file into it

Â Â Â Â # Find the disk device of the card you inserted, say diskN

Â Â Â Â sudo diskutil list

Â Â Â Â # Unmount the disk images

Â Â Â Â sudo diskutil unmountDisk /dev/diskN

Â Â Â Â # Copy the image - This automatically remounts the disk

Â Â Â Â sudo dd if=cubieboard2.img of=/dev/rdiskN bs=64k

Â Â Â Â # Unmount the image and eject

Â Â Â Â sudo diskutil unmountDisk /dev/diskN

Â Â Â Â # Insert SDcard into Cubieboard, connect the Cubieboard power & network.

Â Â Â Â # The cubieboard will obtain an IP address via DHCP and will also

Â Â Â Â # broadcast itself on Bonjour (Zeroconf) under the name

Â Â Â Â # 'cubieboard2.local.' (note the dot at the end). ÂSo you should be able

Â Â Â Â # to connect the cubieboard to your local network with an ethernet cable

Â Â Â Â # and then do

Â Â Â Â ssh mirage@xxxxxxxxxxxxxxxxx.

Â Â Â Â # (password is 'mirage') and voila! you're connected.

Step 10: Install Mirage.

Â Â Â Â Â# We follow the instructions at http://openmirage.org/wiki/install,

Â Â Â Â Â# except that we can skip the first section, 'Requirements'.

Â Â Â Â Âopam init

Â Â Â Â Âeval `opam config env`

Â Â Â Â Âopam install mirage

Step 11: Build Hello, World! example, UNIX version.

Â Â Â Â Âgit clone https://github.com/mirage/mirage-skeleton

Â Â Â Â Âcd mirage-skeleton

Â Â Â Â Âcd console

Â Â Â Â Âmirage configure --unix

Â Â Â Â Âmake depend

Â Â Â Â Âmake

Â Â Â Â Â./mir-console

Step 12: Build Hello, World! example, Xen version [FAILED!].

Â Â Â Â Âmirage configure --xen

Â Â Â Â ÂFails while compiling mirage-xen 1.1.1 with the C compiler cc

Â Â Â Â Âcomplaining about some unrecognized command line options

Â Â Â Â Âcc: error: unrecognized command line option â-m64â

Â Â Â Â Âcc: error: unrecognized command line option â-mno-red-zoneâ

Â Â Â Â Âcc: error: unrecognized command line option â-momit-leaf-frame-pointerâ

Â Â Â Â Âcc: error: unrecognized command line option â-mfancy-math-387â

Â Â Â Â ÂThe full log is at <https://gist.github.com/nojb/b7972e42e317160771c5>.
