Re: Virtual Machines & Binary Compatibilty

2019-09-01 Thread Richard L. Hamilton
All other things being kind of equal, I think I'd favor a host for the VM whose 
CPU generation was at least as new as what the guest OS would have originally 
run on, but as close as possible, of the available hosts.  Mostly I'd suppose 
an older OS could ignore features of a newer CPU that it didn't use...mostly.  
But at the OS kernel level, compatibility issues that can usually be ignored at 
the application level (unless one attempts CPU-specific optimization) may 
exist. So the closer host and guest native CPU generations, IMO the better.

Curious what you mean by "hard-code the screen size" for macOS/OSX on 
VirtualBox (not looking for Hackintosh, would be running on a macOS Mojave or 
later host).  Easy macOS guest (usually the latest in the first few weeks after 
full release) is my main reason for Parallels, although If I get my hands on a 
working Snow Leopard Server DVD (or maybe polish the one I've got so it's fully 
readable?), I'd like to virtualize Snow Leopard too (being the last with 
Rosetta, and on which some rather old software can run) too - my 2007 Mac Mini 
is getting very old and cranky.  If I could have both Snow Leopard and Catalina 
(when past beta) guests on VirtualBox, I wouldn't need to spend for Parallels 
(although Parallels Access is nice, not that I don't have free alternatives 
there too); VirtualBox does best for Solaris (since there are guest extensions 
for it) and ok for CentOS or Ubuntu (the other guests I mainly run), and decent 
even for OS's like Haiku (open source BeOS successor), ReactOS (open source OS 
aiming for Windows compatibility), and even Syllable and I think Kolibri 
(doesn't do Plan 9 nicely though, that one's disk driver is more ancient than 
anything VirtualBox handles well).  So there's not much that runs on x86/x86-64 
that I've tried that VirtualBox can't handle, give or take pain getting macOS 
working on it.  I still think Parallels does Windows a bit nicer than 
VirtualBox, though.

But for really weird (IBM and Burroughs mainframes, PDP-11, Apollo 
workstation), it still takes emulators, since their CPUs are so different. I 
think I collect OS's.  That, or OD-ing on geeky nostalgia. :-)

I've done a clean install from scratch of 10.13.x in VirtualBox.
The only limitation is, that you'll have to hard-code the screen-size.
It's also possible to port this to a WinTel 10 machine.

The reason I'm interested in using a VM for 10.3.6 is, that I'm
currently making my toolchain universal on a 32 bit Core Duo in order to
be able to rsync this to my 64 bit Core 2 Duo because
LibcxxOnOlderSystems currently is sevely broken ... and it's taking
郎ages郎. Also, the MacPro has 12 CPU cores / 24 threads, and it's
blisteringly fast when compiling clang & llvm et al.

Alternatively, I could use my Core i7 MacBook Pro if that's a better
choice CPU vise ?!?

Sure -- almost all the buildbots run in VMs, after all :>

It runs VMWare, I believe Ryan has said.

The ports that are cpu specific are generally forced to build locally.

I use VirtualBox for 10.4 Intel and 10.6 32bit (and a bunch of older Windows 
systems -- windows95, windows98, windows2000, etc).

I use Parallels for 10.5 - 10.14. For 10.5 and 10.6 you need server editions of 
MacOS, as mentioned.

I use qemu for 10.4 PPC and 10.5 PPC on a MacPro 5,1, but that is really 
stretching it I guess 

To share local archives, I do this:

https://trac.macports.org/wiki/howto/ShareArchives2

I have a huge library of > 800 ports built for 10.4 PPC, and more than that 
built for 10.5 Intel and 10.6/libc++ shared locally.

Re: Virtual Machines & Binary Compatibilty

2019-08-31 Thread Richard L. Hamilton
I don't know how it is now, but macOS/OS X clients on VirtualBox used to be a 
real pain to set up, starting with an ancient version of OS X and then updating 
to the desired level, with fingers crossed. Parallels (yearly subscription fee) 
is much better, but I know it does enforce the Server requirement (see next 
paragraph).

Also, for Snow Leopard, the OS license requires that OS and client both be OS X 
Server, and virtualization software will probably enforce that regarding the 
client (although by creating the right file in the image, it might be possible 
to fake having Server).  Good luck getting media for that.

Additionally, where non-identical CPUs are involved, I think some ports need to 
be built locally, because of the optimizations they do.  I think ffmpeg may be 
one, and one or more math libraries also; but I don't know of any authoritative 
list of those.  I think one might suppose that ports for which no prebuilt 
binaries exist (even for newer OS versions) might be among those, but I don't 
know of any straightforward way to construct an authoritative list of such 
packages, either.

There are a few files outside of /opt/local (or whatever installation 
directory), such as those in /Applications/MacPorts, and probably some in 
/Library/LaunchDaemons and/or /Library/LaunchAgents; maybe
a few others too.  One could in principle find them all by running port 
contents installed  and inspecting the output.

But even then copying installations from one machine to the other, unless they 
were the same year and model and CPU and of course OS version, would IMO be a 
really bad idea.

I haven't done it, but there are in general ways to build and package port 
binaries, which can then be made available to other machines.  There's probably 
documentation available for how to do that. Again, there will be ports for 
which that's not a good idea either. So expect to have to learn some things, 
dig around, ask more questions  etc, if you want to do it right. :-)  I don't 
have the answers, not having been involved in the creation of any of this, nor 
having had the need to pursue such things for myself, as yet.
