Solaris 2.4 on Qemu (SPARC)

Posted on by

Well after a lot of digging around, I was able to come up with Solaris 2.4 and proceeded to install it on QEMU.

And it works!

From my notes though, it was far easier to use Solaris 2.9’s “format” command to prepare a 2GB hard disk. For some reason Solaris 2.4’s format command didn’t want to write the label to the disk.

But with a labeled disk in hand, and placing the ISO image under the “hdb” position I was able to boot up the installer with a simple

boot disk1:d

During the installation, you can select networking, just remember that the ip address you’ll use is 10.0.2.15, the workstation is networked with a netmask of 255.255.255.0 and you should use the “other” method of resolving names.

As mentioned in the FAQ, don’t let the installer reboot when it’s done (it’s an option), be sure to do the following:

cd /a/etc
# cat >> system
set scsi_options=0x58
^D

Otherwise it’ll load up the drivers in the wrong order, and it won’t mount the root partition… The best part, is that the networking works great, and that I’m able to telnet INTO the VM, and out of the VM.

And you will want a default route…

# cat > defaultrouter
10.0.2.2
^D

Then in the file /etc/nsswitch.conf change the following:

hosts: files

to

hosts: files dns

Then to ‘fix’ up your /etc/resolv.conf

# cat > resolv.conf
nameserver 10.0.2.3
#

And then I like to add the following hosts to speed up telnet…

# cat >> hosts
10.0.2.2 qemunat
10.0.2.3 qemudns
^D

Then finally (yes!) the file /etc/default/login

comment out the line:

CONSOLE=/dev/console

Now you should be good to go!

Or at lest those are the steps I took to make my system boot. Oh, and don’t forget it won’t auto boot, you’ll have to issue

boot disk0

every time you fire up Qemu.

Back to 386 BSD

Well gunkies is getting a little more life to it, and Dugo contributed this install guide for 386 BSD. Along the way I installed it again with floppy images, and I hit the same fault again:

/386bsd: wd0a: overlaps open partition (b)

However this time I noticed that if you keep on rebooting, it’ll actually stop complaining and work!

So not only was I able to recover from a crash after trying to install the source code, but I was able to complete the install, and install the patchkits! What this has resulted in, is that Qemu can now run 386BSD!!! And it’s significantly faster then Bochs. Not to mention you gain the whole SLiRP / Usermode networking.

So far I’ve tested this with Qemu-0.11.0 just fine. I’m not sure about other levels… so it’s another YMMV.

So now I’ve been able to not only rebuild the kernel & world, but the following programs:

gzip 1.2.4
unzip 5.52
irc II-4.4
lynx 2.8.2

Oh yeah, and another f2c build, and yes it’ll run Dungeon!

So for the few people interested in some BSD history, as this is the ‘first’ Net/2 derived freely available release in a qemu format right here (sorry, link removed, if you want it install this instead).

Just uncompress the qcow2 file (sorry it’ll blow out to 500MB), then run Qemu something like this:

i386-softmmu/qemu.exe -L pc-bios -hda bsd386.qcow2 -M isapc -net nic -net user -no-reboot -m 256

And with any luck, you’ll find the VM booting, and all set and ready to roll. If it comes up in single user-mode, just close Qemu & fire it up again..

I’ll probably put together a windows install package for this later, but for now I figure I’ll unleash some 386BSD onto the world.

More CDROM madness.

Well I found that one of the things that was preventing me from booting up this “Solaris 1.1.2” AKA SunOS 4.1.4 CD is that Qemu on Win32 using raw devices has issues with all these slices and whatnot.

Slices you say?

Yeah, back in the ISO9660 Rock Ridge days, CD-ROMS were basically given a common format for the “LCD” of the day. In that case MS-DOS. Naturally people like Unix vendors were not to keen on that, as they wanted file attributes, long file names, symbolic links etc… So a *LOT* of people started to split up their CD’s into partitions like hard disks, and slap down actual filesystems on the disks. NeXT just used one giant partition on the CD-ROM, but their exe format let them ‘bind’ all the CISC machines onto one CD, and all the RISC machines on another. Meanwhile SUN decided to make all these ‘boot’ partitions for various machines, a miniroot, then an I9660 partition for basic tar files of the OS…

Like this:

2,998,272 DEBUGGING
4,161,536 DEMO
3,219,456 GAMES
1,826,816 GRAPHICS
999,424 INSTALL
1,073,152 NETWORKING
7,815,168 OPENWINDOWS_DEMO
9,748,480 OPENWINDOWS_FONTS
23,756,800 OPENWINDOWS_PROGRAMMERS
34,316,288 OPENWINDOWS_USERS
925,696 RFS
327,680 SECURITY
1,409,024 SHLIB_CUSTOM
524,288 SUNVIEW_DEMO
1,884,160 SUNVIEW_PROGRAMMERS
2,727,936 SUNVIEW_USERS
4,104,192 SYSTEM_V
729,088 TEXT
49,152 TLI
7,872,512 USER_DIAG
29,638,656 USR
622,592 UUCP
6,103,040 VERSATEC

Which is kind of funny seeing how some BSD derived OS’s still keep some of these package names alive.

Anyways, the problem is that I tried to use \\.\d: for the cdrom, and booting didn’t work at all. I even tried reading an ISO from the CD, but all it ended up doing was skipping to the ISO9660 part, and dumping that, ignoring the slices, giving me this:

243,599,360 sol14.iso

So after googling around, trying to at least find a way to back up this CD (it was a souvenir from Japan!) I found someone mentioning to backup their Solaris CD, they had to use the “readcd” program.

Well, I’d never explored that much with the cdrtools, but behold there is a readcd program that’ll dump an entire CD out!

So running it with –scan-bus to find your CD drive…

readcd -scanbus
scsibus0:
0,0,0 0) *
0,1,0 1) ‘HL-DT-ST’ ‘BDDVDRW GBC-H20L’ ‘1.B8’ Removable CD-ROM
0,2,0 2) *

We can go on to dump a full image of the CD.

readcd -dev=0,1,0 f=sunos.iso

Which now gives us a much larger ISO image…

329,605,120 sunos.iso

Sadly it crashes on bootup… But on Win32 it’s a lot better then not reading *ANYTHING* at all!

–edit

I should also add that Qemu’s CDROM (like 99% in the world) are fixed block, while SUN (and other vendors) had these CD ROM’s that could change block size… So in Qemu you have to use the DISK driver vs the CDROM driver….

ie use -hdb sunos.iso instead of -cdrom sunos.iso

Qemu Sparc snapshot getting better!

Thanks to Artyom Tarasenko‘s tireless work on the Sparc MMU, DMA, SCSI It’s not possible to install some versions of Solaris, and boot others to single user mode!
Heck, even the NeXTSTEP 3.3 boot program goes ahead and loads up..

However this is all done without a graphical console, as the sparc rom’s dont understand the framebuffer that Qemu emulates…

qemu-system-sparc.exe -nographic -monitor null -serial mon:telnet:127.0.0.1:23,server -bios ..\ss5-170.bin -M SS-5 -m 256 -hda ..\solaris.disk -startdate “2009-12-13” -cdrom \temp\cd46.iso

Running it is something like this. The key here is the lines:

-nographic -monitor null -serial mon:telnet:127.0.0.1:23,server

Which setup a serial port console you can just telnet into (for us Windows users).

This gets around all the errors like this:

chardev: backend “stdio” not found
qemu: could not open serial device ‘mon:stdio’: Result too large

Sadly my SunOS cd doesn’t seem to want to boot, and I somehow saved a copy of Solaris 8, but not 6..? Sigh.

Which is all cool. And check the CPU, 1070Mhz! Don’t we all wish we had SPARC’s that fast!

I’ve even managed to install OpenBSD/Sparc! … But it crashed on booting.

Anyways it’s late, and thats it for now.

NetBSD 1.5.1 follow up

Posted on by

I figured I’d share what I had, and allow people to download my disk image, and for win32 users, it has all the bits to go…

Just extract THIS zip file, and then run the mips.cmd file, and you’ll be in NetBSD ARC/MIPS land in no time!

Other platforms will need to build Qemu 0.12.3 and use the mips 64bit little endian emulator to run the disk image…

NetBSD 1.5.1 – arc

Posted on by

Well… I was looking around for another OS that’d run on a MAGNUM (ie ARC MIPS in little endian mode), and I found that NetBSD supports the ARC Magnum, unlike OpenBSD.

Sadly it’s *VERY* touchy…. The current version 5.0.2 crashes when unpacking the distribution… However 1.5.1 runs! … kind of.

NetBSD 1.5.1 for the ARC has no install program… So I had to prepare a system partition with Windows NT, then boot that disk under the i386 qemu emulator with NetBSD 1.5.1, setup the disk, and unpack the distro.

From there it was a matter of rigging the ARC loader to boot up an ecoff kernel.

There were a few files in the /etc directory to ‘fix’ to allow normal booting (fstab/rc.conf) and to make sure there is no /netbsd in the root.. For some reason while extracting symbols for the ps tables and whatnot it CRASHES.

So far I’m having issues with the networking, but it is running!

I may have to do some more experimenting with this to see if later versions of NetBSD can get their networking going… The ‘big’ issue at the moment is the ethernet reports a MAC address of all zeros… While the same nvram file in Windows NT works just happily……..

Oh well, here is a screen shot!

NetBSD 1.5.1 ARC on Qemu 0.12.3

NetBSD 1.5.1 ARC on Qemu 0.12.3

I guess it’s worth mentioning that once it boots up, it’s been stable enough for me to rebuild a kernel.. And the kernel even booted! (but transferring it out was such a major ordeal…)

Oh, and of course it runs dungeon!

Qemu 0.12.3 win32 build available

Posted on by

Hot off the compiler….

http://vpsland.superglobalmegacorp.com/install/qemu-0.12.3.zip

I even remembered to strip the exe’s so it’s WAY smaller then the other versions….

Also for those *ONLY* interested in x86 emulation (ie regular PC) I’ve created a far smaller archive here, that only contains the pc emulator.

I figure the amount of people that run the non x86 stuff is few & far between.

Qemu 12.3 is out!

didn’t the time fly by?

Anyways scanning through the list I see that the SDL full screen/windowing has been fixed!

I’ll have to crank out some binaries later, but I had to write something here, otherwise I’d forget it.

Also on the topic of Qemu, I see this site qemu-buch.de has me listed as the latest win32 build site for Qemu on Win32…

Cool!
