Mike, I found this on the IBM z/VM 4.3 FAQs. It looks like you might be 1 release too early OS/390 V2R10 is the first supported when z/VM runs in 64 bit mode.
Question: What is supported when z/VM V4 is running in 64-bit mode? Answer: z/VM V4 exploits and supports the z/ArchitectureT enabling you to run 64-bit capable operating systems (OS/390 V2R10, z/OST, and Linux for zSeries) as guests of z/VM V4 when z/VM V4 is running on a zSeries server in 64-bit mode. A z/VM V4 guest operating system running in ESA/390 mode such as VSE/ESA, TPF, OS/390, Linux for S/390, or VM/ESA may realize performance benefits from additional central storage when z/VM V4 is operating in 64-bit mode. In order for z/OS to operate as a guest of z/VM on a zSeries server, both z/VM V4 and z/OS must be operating in 64-bit mode. Richard R.

Perfectly good question, especially since this system does have an IFL.... But, this VM is only on the CP, there is a separate VM for the IFL. Also, I am successfully running a zOS 1.5, zOS 1.8 and two VSE 2.7.3 systems on this same VM where OS/390 refuses to run. Thanks Mike C. M.
