Hi!

Is there a way of running OpenVMS in a virtual machine?

Or is there a VAX emulator at all?

Cheers,

SimH under Windows or Linux running the VAX emulator is doable.

Haven't really performance tested it, though.

You can emulate a VAX using CHARON-VAX:

You can also emulate an Alpha:

Yes, I am running OpenVMS on Personal Alpha running on Windows XP
running on a virtual machine by VMware Fusion on Mac OS X.

Of course, this is not a production environment!

I run it under FreeBSD and OS/2 as well!

PT_VAX.EXE from SRI [1] says it runs at 10 VUPS on my notebook (1.5 GHz
Pentium M, 1.2 GB RAM).

Sequential test results:

Run 1 7.3 24752 10.0
Run 2 7.3 24752 10.0

Average 7.3 24064 10.0

Interleaved test results:

I'm running a SIMH-VAX on a 64-Bit Sun Microsystems ULTRA-1 Model 140,
with 64-Bit OpenBSD 4.4 for sparc64/sun4u architectures! It's really
faster and securer as in/on SOLARIS, or even SunOS 5.x :-)

Yes there is simh which emulates a VAX 3900.
Simh runs on VAX, Windows, Linux and other platforms. A few ready to
run kits (old but working) may be found on
http://home.zonnet.nl/hvlems
No VMS media, just the compiled emulator.

There's also a VX-11/780 version now...!

I intend to set up a ready-to-run repository when I get time...

Must compile SIMH for the VAX sometime...virtual VMS! Pretty slow though
on my VAXes...

In addition to a virtual machine that is an emulation of the hardware
that VMS runs on, there is also the market-speak meaning of virtual
machine. VMS runs in an HP-UX based VM on IA64.

It many ways it is the same meaning since it does the same thing - it
is just a bit faster when the virtual machines has the same instruction
set as the host machine.

But under the hood, there are huge differences on how the guest IOS is
told about devices and how much control it has over such devices.

It is the same that Microsoft Virtual Server 2005 does.

And the same that VMWare Server (not ESX) does.

The virtual machine created by the HP emulator on Integrity is an Integrity server. It
can be a great way to partition hardware a big Integrity server into lots of little ones.

"Hey, it runs OpenVMS, right?" is about all the technical knowledge the non-VMS sales
reps know. If the customer is looking for a virtual solution to replace a "stuck-on"
VAX, that just won't work.

I won't mention CHARON-VAX on Intetrity as a way to help these people. [Shameless Plug

Does it now? Or is it still a promise that it will one day. I'm afraid
I'm a bit lost with respect to the difference between marketing
brochures and really restoring your VMS backup on such a VM.

VMS 8.4 is to have support for this. It is close to being hatched to
customers from what I have been told.

No. Fieldtest for VMS 8.4 was recently delayed until end of year (!), so
I don't expect to see a final V8.4 before 2010H1. So much for the promise
of 12-18mon between every major VMS version (IIRC Nemo was mid 2006)...

That is most interesting. I suspect this is due to various changes going
on within HP and not to 8.4 not being complete.

And, as far as the perception of the IT Industry, does the reason
really matter? Or will they just see it as another legacy product
not receiving the attention or resources it needs to stay on schedule?

The industry doesn't know that VMS is slated to get a new version so the
delay is inconsequential to the industry.

However, should HP decide to announce new plans for VMS, IA64 etc, then
this delay would slip right in with the new plans and the reason for the
delay perfectly valid.

Hi guys!

The EmuVM company (http://emuvm.com/) has developed Alpha AXP emulator running on Linux and Windows called AlphaVM. The OpenVMS and Tru64 can be launched on it.
We have free and commercial version of AlphaVM emulator.

Please, visit http://emuvm.com/ and find it.

hi

i have open vms alpha versions

SOFTWARE
───────────
VMS V7.3-2 prod server 1
VMS V7.3 prod server 2
VMS V7.3-2 prod server 3

Now if i want to go virtulization what is the benefits i will get?
is there hardware need to be added what is the cost?

after virtulization i need to both vms and windows server?

can you please explain?

OpenVMS Alpha cannot be virtualized.

Virtualization, VMware and Xen, and OpenVMS?
<http://labs.hoffmanlabs.com/node/640>

OpenVMS Hardware Intro: Hardware Emulation
<http://labs.hoffmanlabs.com/node/70>

Also read through the years-old newsgroup thread that you've replied to
<https://groups.google.com/d/msg/comp.os.vms/XXr12jKPskE/CIWKHcrP_0sJ>,
and please try to explain what in that thread you might find confusing.
That'll help speed an answer.

If you have questions on the thread or on the above links, please do
ask. Again, specifics help.

As for whether you will see any benefits from emulation or from a
virtualized emulator, that is only something you can answer, and
probably only after testing to see whether your applications work, and
whether the emulation has sufficient performance. Depending on the
environment and on the dependencies, porting to OpenVMS I64 can have
good or potentially better results, too. Trade-offs and applications
and the local system loading will all differ; there's no
one-size-fits-all answer here.

Some terms...

Emulation: different computing architectures. Alpha executables
running on x86-64 systems require both instruction emulation and system
simulation; they won't run natively, so you'll need an emulator to run
the binaries and the operating system. An emulator requires an
operating system; either a home-grown operating system that was
custom-written for the emulator and that provides basic OS-related
functions, and some emulators are packaged with a generic operating
system, while others are treated as layered products and are installed
onto the end-user's own hardware and operating system. Emulators can
often be virtualized.

Virtualization: the binary is executing on the same underlying
architecture as it was built for. x86-64 binaries running on an
x86-64 system can run more-or-less directly, and there's no difference
in the instruction sets.

And entirely FWIW, please don't dredge up an ancient posting. If you
do feel oblicated to dredge up an ancient newsgroup posting, then
please explain why your question is different from what was discussed
in the previous thread; what you don't understand about what was
posted. You've clearly used a search engine, so the least you can do
to better reach your goal of an answer is explain why the question
you're asking differs from the answers and the discussion you've
clearly already found.
