Yesterday I posted the DRS Deepdive. One of the questions still left open was how DRS decides which VM to move to create a balance cluster. After a lot of digging for non-NDA info I found this “procedure” in a VMworld presentation(TA16) amongst some other cool info.

Rob de Veij just uploaded a new version of RVTools. Check it out, there are a whole bunch of new cool features added. Honestly one of the best free tools around, great work Rob! (Everyone keep in mind that Rob does this during the evening so if you’re using this for commercial purposes would be nice to make a small [...]
