+Guest Operating System Support
+==============================
+
+There are a number of possibilities regarding the guest operating systems which can be spawned
+on the nodes. The current system spawns virtual machines for VCP VMs on the KVM nodes  and VMs
+requested by users in OpenStack compute nodes. Currently the system supports the following
+UEFI-images for the guests:

+The above table covers only UEFI image and implies OVMF/AAVMF firmware on the host. An x86 deployment
+also supports non-UEFI images, however that choice is up to the underlying hardware and the administrator
+to make.

+The images for the above operating systems can be found in their respective websites.
