I can personally confirm proxmox 6.4 and sco openserver 6 definitive will work
under the vm’s “optios” tab kvm hast to be disabled
hardware > processor type = qemu 64 (32 probably works too i just know this is what got it going for me today)
network: e1000
drive type sata or ide
i cycled through all the options for drive type. i noticed in the os6 install theres a load extra hba drivers and a megasas flashed across the screen but alas it will only see a sata or ide virtual drive.

never have i found an os i hated as completely or as quickly as this beast.

Hey there!

I’d probably try using regular QEMU without the KVM flag, and just trying older versions to see how they fare.

Unfortunately Qemu/KVM is chasing the bleeding edge, and anything that is old that works in any state is coincidental. VMware may be another option, or Hyper-V if you need it to work.

I was hoping to ask if you’ve had any experience with UnixWare 7.1.4 running on KVM. Following your guide got me pretty far, but I can’t seem to get the system to boot past the logo. Right after the XINUOS boot logo appears, I get a kernel panic warning with the following message: “PANIC: General Protection Fault trap in kernel mode.” Booting into single-user mode as well as attempting some other boot parameters without success (an old SCO guide I found online suggested manually setting the “MEMRANGE” parameter from the SCO boot menu).

What’s interesting with 7.1.4, if I set the CPU flag to “pentium” the system boot loops about 1 second into the boot process, where as if I set the processor flag to “host”, I can at least get the system to show the kernel panic message. I wonder what could have changed between versions that makes running on KVM so difficult.

Thanks again for your article!

Yeah as qemu drifts further and further away from basic PC emulation you have to get far more specific with the component flags to get what you want.

It’s a shame, it makes Qemu look more and more frail, while it’s becoming more capable.

Can anyone help?

I’ve only used Merge in data centres, or over X-terminals so I’ve never had audio, or if it was there, there was no way I could hear it.

I’d guess, probably not.

I keep forgetting to put in a ‘dos diskette drive’ so I can finish setting up merge, although I was more excited to get onto the network and run the compiler.
