Xen Provider

UniK supports running unikernels on Xen. In order to run on Xen, you must have xen-hypervisor-amd64 installed, and xl must be a valid command. Running Xen commands with unik may require launching the daemon as root.

Currently UniK is configured to run only paravirtualized (not HVM) VMs with Xen.

To run UniK instances with Xen, add a Xen stub to your daemon-config.yaml:

providers:
  #...
  xen:
    - name: my-xen
      xen_bridge: xenbr0
      pv_kernel: /home/ubuntu/xen/dist/install/usr/local/lib/xen/boot/pv-grub-x86_64.gz

xen_bridge specifies the name of the bridged interface configured for use with Xen. If you don't have a xen bridge set up, see the instructions at https://help.ubuntu.com/community/Xen.

pv_kernel specifies the path to a pv grub boot manager. To install pv-grub, follow the instructions here: https://wiki.xen.org/wiki/PvGrub#Build
