qemu-system-sparc (x2) on Linux host + VDE2 + distcc

[Andrew-R]

Well, I finally did it! (had this idea for looong ime, to try and network two qemu instances so they can compile stuff together)

Re: multiple qemu networking together and with host (Linux host)

I am not sure if it makes sense for PowerPC/OSX as host (new qemu is no go there) but because some qemu machines only single CPU, or, like in sparc case -smp 2 is unstable in NetBSD this can be useful for some speedups!


I used this guide as starting point:

<p name="f282"><inline>This HOW-TO explains a quick and easy way to speed up NetBSD pkgsrc compiling on retrocomputers. It was written because there are altogether too many distcc how-tos which are complex, require special build environments or make assumptions without explaining what's going on...

and this page for qemu networking:

There also was lnk for OSX 10.4/10.3 PPC cross-compiler setup

MacOS X and Distcc | Left 404

But I m not sure how well you can replicate that (re to all those users who have slow ppc laptops).

lol, it even works (today I learned that our cloud provider can also host simple static websites (Google apparently can too, like Amazon Web Services ...) and used s3cmd (+ also firefox browser 140.something from Slackware 15.0 - so not purely modern-free solution) for uploading NetBSD/sparc packages to it, with listing generated by 'tree' command as suggested at

How can I create a simple index.html file which lists all files/directories?

We use a web server that does not allow directory listing. There is a specific directory I would like to allow listing of. How can make a simple HTML file that will contain the contents of this

And now more fun: I added NetBSD/macppc to same virtual network! It displays cinelerra-gg from virtual netBSD/sparc, because TCX emulation in qemu show swapped red/blue colors..

Attached: 1 image Hard to see whats going on but I put netBSD/sparc and netBSD/macppc (both in qemu) on same VDE network. And run cinelerra-gg from Sparc to Mac :)

qemu-system-ppc -cdrom ~/ISO/NetBSD-10.0-macppc.iso -hda ~/QEMU/Mac-netbsd-2gb.qcow2  -M mac99,via=pmu -boot c -prom-env  'boot-device=hd:,ofwboot.xcf;1' -net nic,macaddr=52:54:00:02:12:23,model=ne2k_pci -net vde,sock=/tmp/vde.qemux0 -g 1024x768x32

Ran X server on "mac" side as

"startx -- -listen tcp -ac" (I know no access control is a bad idea, in general).

Now everything seems to have correct colors. Cinelerra-gg launched from LE host displays OK in NetBSD/macppc machine, too. And I can send cinelerra-gg UI and main video windows from "Sparc" side to LE (i586) X host as well. A lot of fun, too sad glx seems to be broken between BE and LE X servers
