This script was created to spin up a working instance of Xen-Orchestra (community edition) from a newly installed XCP-ng server cli easily. It creates a VM to run openSUSE MicroOS + docker-compose to use this image.

yum upgrade -y && yum autoremove -y #update to get the correct guest-util ISO version
/opt/xensource/libexec/xen-cmdline --set-xen dom0_mem=2048M,max:2048M && reboot #set dom0 memory
wget https://raw.githubusercontent.com/HPPinata/Xen-Orchestra-Install/main/createVM.bash
cat createVM.bash #look at the things you download
bash createVM.bash

After the script completes the host reboots, then the Xen-Orchestra interface should be reachable on the IP address your DHCP server assigned to the VM on ports 80 and 443. The default credentials are admin@admin.net with password admin.

My main goals were to give a starting point for easy customisation (not just a baked vhd file) and have the OS be as manitenance free as possible.

I originally considered Fedora CoreOS, but it requires either a hypervisor backchannel, the coreos-installer package (or a working container environment) to put the configuration file into the install ISO. (I really tried to do it with standard tools; unpack-repack with genisoimage, in place update with xorriso, even hexdump and dd, but the ISO either would not boot or did not pick up the [butane -> ignition -> cpio newc -> xz + padding] config image correctly).

So i went with Opensuse MicroOS instead which allows one to just attatch the configuration (which can even be written in plain bash) as a separate ISO. The guest-utils are installed from the XCP-ng ISO as the openSUSE ones (xen-tools-domU) don't work with XCP-ng.
