We have more than that in our disaster recovery environment and we don't do anything to segregate VM from z/OS there. So, VM is ok with that - it does take longer to IPL though. For production, we separate out by LCU's (VM owns its own) and we restrict the gen so that z/VM can't see the z/OS devices (although z/OS can see z/VM's because it is required for Hyperswap to work). You could also provide segregation in the system config with what is online at IPL and what is "accepted". (sorry for the HTML format - for some reason I can't change it on this particular email - weird).

Can anyone let me know or tell me where can I find the zVM information of the number of devices can zVM support. Will it be any problems if I share the same IOCDS for zOS with zVM, where the number of devices defined in the IOCDS more than 16384. (The number of addresses for DASDs alone is 16384). FYI, we have 6 LPARs on the z9 machine and plan to run zVM on one of the LPARs. All the LPARs in z9 machine are sharing the same IOCDS. Thank you.
