That is the official way to do it (to define a virtual server to run on the IFL(s)). It's just not clear from the doc that you use the COMMAND + the DEFINE instead of some format of the CPU statement as one would expect.
The other option as mentioned here is to dedicate the whole IFL to that virtual server. That might also suit your purposes (but then you won't ever be able to run something else on that one too).

Do you mean it's not very clear from IBM doc on how to define the corresponding part in the directory entry and you submitted a reader's comments to IBM? The command you mentioned below is a workaround, right? COMMAND DEFINE CPU XX TYPE IFL. sorry, English is not my first language...

How to do in user direct file if I want to permanent let this IFL dedicated to that zLinux? I used q cpu to know the CPU id of IFL. e.g. 03 is IFL. I defined CPU 03 in the linux user direct file. But it seems doesn't work. What else did I miss?

So the answer is yes.

If there is a zVM LPAR with both CPs and 1 IFL. Is it possible to let one Linux guest to excluded use this IFL and only use this IFL? (We assume this IFL is dedicated on this LPAR) Thanks!
