Up until now, IncludeOS has been officially tested on Linux KVM (using QEMU for local testing and OpenStack in the cloud) and VirtualBox. It has in fact also been possible to run IncludeOS services on VMWare, but with one very important limitation: no networking.
However, full networking support for IncludeOS on VMWare is now available on the IncludeOS
dev branch, so feel free to try it out. Any feedback or comments very much appreciated!
