For S/390 you simply need to set the hostid in the file at boot
appropriately
by default. (/etc/hostid)
On SuSE 7.0 the hostid file is /var/adm/hostid
Setting it is easy from root (I assume it checks for uid(0) rather than
root - haven't looked at the source yet) with `hostid 12345`. So I

Daniel,
This really is too wide open to answer effectively. If you're running a 2.4
kernel with the jiffies fix (also known as demand-timer or something like
that) your Linux/390 guests under VM will use a lot less virtual storage
than otherwise.
What each individual guest is doing will

questions like this beg to be answered by Well, it depends, but is
there any kind of general rule of thumb for determining what resources
would be required
And I agree with Alan Cox that things like
get-me-a-world-unique-64-bit-number() should be obtained by something
other than the gethostid(). Make such a call part of the POSIX standard
or something. It's not a networking thing. gethostid(), for better or
worse, is.
For pseudo-random
Much like you may have thought, the answer is highly dependent upon what the
instances are running. There are a large number of applications that do not
have large memory footprints. I run a number of Linux virtual machines in
64MB or less or storage. Those machines run DNS (24M), Sendmail

We've had excellent success using VDISK. Gives much better performance than
using a real disk.

Well, the bad news is that they ship some binary programs (vmake is one)
that are Intel-specific for the Linux version of their code. I guess I need
to contact them and ask them to ship the source for their toolkit as well.

substantially faster that any of the others, but it is also a much more

I was wrong.
I misunderstood the nature of gethostid()
and therefore misunderstood the relationship of 'hostid' to it.
Thanks to those who have indulged me in re-education.

This was installed prior to me getting my hands on it. Recently we had our IP
