hp ML 150 gen9 VSphere OS 6.0

Hi all ,

I am very new here, and I have very basic knowledge in networking .

We got one hp ML 150 gen9 server, on this server we want to have 2 - 3 vm running (server 2012 r2), so we decided to go with VSphere OS 6.0 and I got iso file of same from HP team.

So my concern is from where we can get the free license for the same and can we run 2 vm simultaneously here of Window Server 2012 r2.

Kindly suggest me .

Thanks

Gautam
