Don't attach the real reader to the the guest. Just punch the file to
VMTEST.

This is something that I tried at one point.? The file looked like it was punched (according to the system response), but actually stayed in the RDR of MAINT on the top level.

That worked, although I did have to map 00C on the 1st level to 10c on the 2nd level because of a conflict with the virtual RDR already at 00C.

Thank you.

If I attach the reader (00c) from the top level OPERATOR console to

If you're shipping the file from the host os into Hercules, then inject
it with a leading ID card: "ID VMTEST CLASS A".

I've create a 2nd level VM that I will use as a testing sandbox.? Let's call it VMTEST.

I need to copy a virtual card deck to the A minidisk of MAINT on VMTEST.

I understand how to devinit the deck on 00C on the top level VM and to use readcard to place the file on disk.? What I do not understand is how I can map the "real" 00c over to VMTEST so that I can attach it to MAINT on VMTEST.? My attempts so far have not met with success.

If I attach the reader (00c) from the top level OPERATOR console to VMTEST, I see a notification on VMTEST that it has been attached.? However after the devinit on Hercules, the file does not show up via either a Q RDR or Q 00c (which shows as offline).? What am I missing here?

Thanks as always to a great, helpful list!

Oops that should be Hercules Hyperion 4.6.0.....

Hello,

I've downloaded VM370CE 1.1.2 onto my Windows 11 (Pro Insider Review). I already had Hercules 3.0.7 (64 bit) installed.

In the VM370CE directory I ran the batch file "vm370ce" and as expected Hercules started and a WC3270 terminal opened but was unresponsive.

Youtube demos seem to show lots of? messages that end with a display of devices in CP??

Mine doesn't seem to get very far, runs to the end of the script and prompts for Start Command parameters.

Thinking this was a Hercules/Hyperion thing, I installed both Hercules 4.4.0 and 4.7.0 set Paths accordingly, rebooted and reran the Vm3270CE startup again, but with similar results.

It there something obvious I'm doing wrong here? Is there a video somewhere (I haven't found one) that demonstrates a simple startup?

Thanks,

Steve

Perfect!? Must have done this before and promptly forgotten.? That won't happen again!

Please refer to the file readme-virtreal.txt which is in the CE download package (in the root folder unpacked from the distribution).

I've gone down the rabbit hole of CP Nucleus building and and getting the hang of things.? I've made so many change, blown away systems and started over, that I may have confused myself here...

I'm not seeing a VIRT=REAL allocation anymore (using CE 1.2) whereas I used to see 8192k.

I even went back to a download zip file and am not seeing it.? I don't recall, was there something I had to do at the CP level to enable V=R.? Not talking about at the directory level here.

I did see a post relating to the 6 pack referencing VRSIZE but I don't recall running that for CE 1.2...I thought it was already setup with a V=R nucleus.

Someone please help me make sense of out this.

Thank you!

The VM/370 CE 1.2 nucleus is built in uniprocessor mode.? Continuing my learning experience, I'd like to try multiprocessor, on the premise that MVS will use 1 of the processors and everything else the other.

I've looked through a mountain of material and am not sure how to best proceed.? It looks like I'll need to generate a new nucleus.

Might anyone have the steps to follow in a VM/370 CE (or 6 pack) context?

Thanks in advance as always to the brain trust in this group.

Also, if you are running V=R you can get a small additional
performance boost by issuing these two commands after second
level is IPLed:

CP SET STBYPASS VR
CP SET NOTRAN ON

I would also like to remind folks of the importance of defining a different command separator character to your second-level user too (after logging on but before IPLing it), so that "immediate" commands prefixed with a separator character (e.g. "#CP ATTACH...") are processed by the correct level system (i.e. by the first level CP or the second-level CP).

Of course, that only comes into play when you use your first level user's console also as your second-level console too. Otherwise I guess it's not needed? (I forget! It's been a while since I've done this shit!)

Thanks Bob.

BTW, yes, the first level operator console does warn me about the VOLSER dupes, but that is it, just a warning.

Best to all,

Hi Daniel,

For the settings in the CP directory that define the second level VM machine, you should use the same settings that you use for your MVS guest:? OPTION ECMODE BMX REALTIMER

I'd also recommend that you run your second level VM in a V=R area; you can use the same V=R area that you used for MVS (just not both at the same time). If you do decide to run it V=R, then I'd add VIRT=REAL and STFIRST to the OPTION statement items above.? Also, if you are running V=R you can get a small additional performance boost by issuing these two commands after second level is IPLed:

CP SET STBYPASS VR
CP SET NOTRAN ON

Both of these commands are issued to first level VM from the second level virtual machine console.? A CP Q SET command should confirm that you have them set.

And finally, ensure you are running with ECPSVM YES in the Hercules configuration.? Second level is quite painful to use without it.

Regards,
Bob

Thanks to all who offered suggestions.

The suggestion from Fish did in fact work for me as a proof of concept.? I tried that first as it seemed very straightforward.? I booted a shadow copy of my main system.

I created a user VMUVM on level 1:

Now that I know how to do this, I still realize that i need to separate the level 1 and level 2 system DASD, at least where write conflicts will occur.? I'll also need to work on the 2nd level directory.
There were no VOLSER conflicts reported doing things this way.

I'm open to suggestions as far as options/settings for the VMUVM.? It would not IPL without ECMODE, so I know I need that one.

Nothing that you wrote was incorrect, and nothing that I wrote

VM/370 is not z/VM. It's not that it can't be done. But I
wouldn't recommend it for a first-timer.

Fair enough.

But IMO, as long as the person in question is at least not a first-timer when it comes to VM/370 itself (i.e. as long as they're familiar with (have at least *some* experience with) setting up a new VM/370 userid )i.e. VM guest)), then whether they're a first-timer at setting up a 2nd-level VM or not, is fairly immaterial. If you can setup a new guest under VM/370, then you can certainly setup a second-level VM/370 system under VM/370. It's really no different. It's just another VM user after all!
