Due to some precarious applications, a customer is anxious to know now
what release/version of z/VM we're migrating them to in 2007.
We'll migrate them before their VM5.1 is unsupported in 9/2007.
Does anyone have any good rumors about whether a new release or version
of z/VM beyond VM5.2 will
Good luck with that as I cannot get IBM to say when RSU0602 might be
available for z/VM 5.2.0!

I hear rumors that there is a significant bug in z/VM 5.2 that will be fixed in
z/VM 5.3. It is another 2G line constraint having to do with page and segment
tables having to be located in the underworld.

Sure, you can have the print file spooled anywhere in an RSCS network,
whether a user or another

Do you have a real CPU to back up the 2nd virtual CPU? If not, then you
are not gaining anything. The 2nd virtual CPU is being scheduled to work
on the only real CPU just like every other task waiting on CPU. I believe
that the overhead on VM of scheduling the 2nd CPU and the additional work
Hey Scully,
There may be a lot of confusion, but there's only one correct answer: It
depends. :-) Seriously, the SHARE value in the directory (or set by
command) is a function of the virtual machine, not the virtual processor. A
four way with a SHARE of Relative 100 gets a relative 25
While the host is running I copied the host VM5.2's single SPOOL pack to
the single spool pack of my guest VM5.2 system, wanting to give the
guest a copy of the host's NSS's and other System Data Files (SDF).
When I IPL-ed the guest it reported no spool files; it had no NSS's.
I did the copy 3
Let me refine this question.

The underlying CP has no resource constraints. CP SHARE the same for
both users. The only difference is user A has one virtual processor
and user B has two virtual processors.

You need to copy the CHECKPOINT and/or the WARM START areas too. You
will more than likely have to do a FORCE start on the new system.

Ahh, that's' what I'm forgetting. In the past I've copied the sysres and

not this time. Thanks.

Ken,
Can you tell us the level of CP where this happens, and the associated
condition code? I've just spent an hour or so poring over the 5.2
source code for diag A8, and I can't see any way return code 3 can
happen.

David--That's exactly what you cannot do with DCSSBKUP/.RSAV is copy

All things being equal, does giving a user a second (or third) virtual
