In addition to z/VM on IFLs for Linux, z/VM in a standard engine LPAR can provide a low-cost, on-demand test bed for VSE, z/OS, and TPF installations as well. Yes, you will have to pay for z/VM on your standard engines, too, but it may be more cost effective in some cases than using LPARs. To be clear, adding z/VM to the standard engine (CP) side of your box will not increase your z/OS software costs.
