You can download DilOS ISO and USB at: http://www.dilos.org/download

gcc 4.8.3 64bit as default for dilos-illumos and userland builds.

dilos-illumos has been moved to GIT from Mecrurial.

You can use vmxnet3s + pvscsi drivers on VMware ESXi - I have tested on 5.5 version as well.

You are welcome to FreeNode IRC #dilos with questions.
