GUI: VM storage settings page was adjusted a bit in usability regard. User is now allowed to change controller bus type and can move attachments between the controllers by using drag and drop
First of all this made me experiment with 2 SATA controllers (which seems to work if I use chipset ICH9 (under System).
Host OS: Solaris 11.4
Guest OS : Solaris 11.4 - 2 SATA controllers attached to the guest
I can indeed drag and drop disks now between these virtual controllers and this seems to work.
Nice feature ...
