If you want some VMs on your Solaris-machine, Virtualbox is the simple choice. Feels like a dumbed down version of Vmware workstation or Hyper-V on Windows 8, but it seems to do the job for quick testing. Virtualbox should also work fine on a wide variety of OS’es other than Solaris.
A useful tool if you don’t have easy access to the Solaris GUI you may want to try RemoteBox on your Windows-machine. Download from http://sourceforge.net/projects/remotebox/ and see the following for how to get it running on Windows.
