Just upgraded a VM from 9.2-1 to 9.2-2 which seemed to have worked well.
Bearing in mind this us just a hobbyist system, when I created the VM I
gave it 8GB memory, and an 8Gb system disk
That was fine, and it created a 2Mb pagefile, not expecting it to be used.
The autogen run at the end of the upgrade obviously though this was
rubbish, so tried to create an 8Gb pagefile on the system disk. Clearly
it couldn't, so it created one of over 4Gb - leaving me with 120Mb free.
It also wanted an 8Gb dumpfile.
Is any of this sensible?

I believe that is one of the differences between Windows and VMS. On
Windows plenty of RAM and no/small pagefile works fine. VMS want
pagefile backing of virtual memory even if it is not likely to
need it. And running out of pagefile space is bad - very bad. So I got
1 x 8 GB pagefile on my VMS x86-64 and 3 x 1 GB pagefile on
my VMS Alpha (can't remember what I have on my VMS Itanium).
But VSI recommended 8Gb memory, and an 8Gb system disk. So how do we fit
that in? Especially if they want another 8Gb for the dump file

I don't get it. 8 GB RAM makes sense. I would go for 20/30/40/50 GB
disk.
I don't think you need that big a dump file. It may want that big
a dump file, but if I remember correctly then VMS writes a subset
of data if the dumpfile is not big enough for all data. Obviously
if you want perfect analysis of a crash, then a full size dumpfile
may be nice, but ...

On my V9.2-2 install (not upgrade)I created a 24GB system disk. I
allocated 12GB of memory and it creates a 2MB page file. Install left 10.2GB free so Install uses about 14GB on my system. This includes an 11.74GB dump file to match the 11.74GB usable memory. Autoconfig at the
end did not try to make a bigger page file nor create a swapfile.

In a hobbyist situation, do you need a page file that large? Unless you have an app that uses masses of memory, you can probably get away with something smaller. I have 6GB of memory with 3GB of page file, and I
rarely use more than 1% of the page file.
In a hobbyist situation, do you need a dump file? Unless you're doing kernel mode development, perhaps not. Set DUMPBUG=0 in MODPARAMS.DAT, reboot, and delete the dump file.
If you do want a dump file, you can probably get away with something
much smaller by specifying an appropriate value for DUMPSTYLE in MODPARAMS.DAT. You should at least compress the dump by setting bit 3,
and choose other bits for that parameter based on your circumstances.
Remember, if a dump file doesn't exist either in SYS$SYSTEM: or in a
DOSD location that you've specified, VMS will use the page file to write
the crash dump.

I'm not sure where you saw that, but section 1.2.1 of the V9.2-2 Install says: https://docs.vmssoftware.com/vsi-openvms-x86-64-v922-installation-guide/#d0e99
Memory: 8 GB.
Note that if your installation fails due to the lack of memory, you can increase the amount of it for the duration of the installation and then,
if needed, reduce it back.
Operating system: Other 64-bit.
A virtual disk for the system files. The disk must be at least 15 GB in
