[Qemu-devel] SCO Unixware 2.1.x on qemu

[Diego Woitasen]

Hi,
 I know this is not the right place to ask this, but the user forum is
broken. Anyone has experiencie virtualizing SCO Unixware 2.1.x with
QEMU? In my work we have four servers that we can't drop or migrate to
a new platform and want to upgrade the hardware (they are 1995
machines). The Unix installer starts, detect hard disks but doesn't
recognise the CDROM. I've tried it as secondary master and primary
slave (in this case, installation hangs checking hardware).

If someone send me a tip it will be apreciated.

Regards,
  Diego

Have you checked you the Official OS Support List?

Yes, Andrew got SCO Unix 2.1.3 running on QEMU (an old version). He
said that works taking a raw image from a real PC installation but
there are no details. I've just found an old HP workstation (Pentium
100, ide). I will try the same procedure.

If someone has more information, pleaes let me know...

 Diego

Unixware 2.1.3 should install with Vmware Server. After that you can convert the image to Qemu and try booting your freshly installed system.

I tried with VMware 2.x and VMware workstation 6.x and didn't work.
They didn't boot the boot floppy because the lack of boot signature I
think.

The installation works with QEMU but it doesn't detect the CDROM. Is
there something new in the virtual cdrom that makes Unixware fails on
its detection? Is there something in the code that I could change? I
trie'd my floppies and the CD on an old HP machine and works but the
CDROM must have to be connected as primary slave. Using "-drive
index=1...." doesn't work with QEMU.

 Diego

Looks like I've misplaced my installation disks so I am afraid I cannot help. I know that I've used Vmware Server back in 2006 to install Unixware 2.1.3 succesfully.

Justin Chevrier sent some patches for an SCO OpenServer guest, last  
fall/winter. Part of it were some SCSI fixes iirc, so you could try  
emulating a SCSI rather than IDE CD-ROM drive.
You might also want to check whether all the SCO-related patches  
actually got committed. Patches for non-mainstream guests or hosts  
tend to get less attention.

Note that OpenServer is not related to Unixware 2.x at all.  OpenServer
was the last incarnation of the SVR3-based SCO Unix, while Unixware 2.x
was the straight SVR4.2MP they acquired later.

I've found a solution. I installed Unixware on an old HP PC (Pentium
100, IDE) and then took an image with "dd", and works without any
special trip. I'm using QEMU 0.9.1 (Debian Lenny package) because the
lateset version fails, Unixware reports a timeout error with the disk
controller.

Fwiw, I just installed SCO OpenServer 5.0.7 using kvm-88 and it did
worse than fail: it *froze my whole PC*.  It happened early on while
booting from CD and checking hardware.  Power cycle needd.  Thanks guys :-)

Installing it on qemu-0.10.0-1ubuntu1 worked quite well.

You aren't doing anything crazy like running both vmware and kvm at the
same time are you?

Impresive that you can lockup the PC.

No, just kvm, nothing fancy.  Not even kqemu.
kvm is good enough that I don't use vmware these days ;-)

"Impressive" isn't the word that comes to mind.  "Exploitable" maybe :-)

There's a small chance it was the X server.  That tends to lock up
occasionally at random, so I'll have to try it again to confirm.
OpenServer was probing the IDE disk at the time, so it looks suspicious.

Anyone has the Unixware 2.1.3 media kit? 2.1 works on QEMU 0.9.1 only
but QEMU hangs when there is high I/O activity. With versions 0.10.x
UW 2.1 doesn't boot and the kernel prints an error about IDE
controller timeout.
