I wanted to have a desktop OS capable of running Dtrace/ZFS/KVM native'ly. Thus I set out on the path of exploring SmartOS/OpenIndiana/Illumos etc.
In parallel, I continued my efforts to compile these on my Ubuntu VM. VM first because I wanted to make sure I handled/iron'ed out most of the issues using these before I shift it to real h/w.
Somehow KVM inside VBOX Ubuntu guest is not working. Though I am less worried about this as, I know a VT capable processor running Ubuntu would help this resolve( or may be its issue with VBOX not supporting VT under VT for h/w virtualization ).
Anyways, I am happy to share that I am able to compile Dtrace4Linux port by Paul Fox. Thanks to him, for directing me to a stable release(17th Jan 2013 released tar). It was easy, the readme had it all that was necessary for this to get going.
