I would say that almost all long-term VM shops run their test VM second level, as you're considering.

We currently have some production zLinux guests running under z/VM 5.1. z/VM is installed as an LPAR on our single Z9 server. We had, until recently, a second Z9 on which I was running a test VM which I could use to apply and verify maintenance and program fixes. After those fixes have been deemed OK, we'd move them to the production VM system (VMPROD). Now, The VMTEST Z9 has gone away and now I'm faced with a choice of creating a second LPAR for VMTEST, or to run VMTEST as a guest under VMPROD. So the question is - is running my VMTEST as a guest of VMPROD good practice? Are there exposures to flawed maintenance or program fixes that wouldn't surface when the platform is running as a VM Guest? How are those of you with current production and test VM systems doing this?
