With a bit of poking around in the latest Qemu 0.15.0 rc2 beta, the S390x now builds by default. Finding something for it to run was a bit of a stretch but I should have figured that Debian would have something.
It does take a few seconds to boot up, and by default you’ll just be sitting at a blank screen until you toggle to the virtcon0 screen.
But it’s VERY snappy… I haven’t gotten it to install (unsupported NIC?!) but I’m pretty positive it’s 100% my fault. I’m just happy I saw it boot. And it runs the busybox stuff just fine so it’s tentatively working.
If anyone wants to give it a whirl, download my exe, and the kernel/init.rd I’ve found that at least boot up here.
I’m hoping this will spur someone to spell out how/what to install onto it, and maybe if things like MUSIC/SP and CMS will run on it… That’d be fantastic!
In the meantime I’d imagine this combined with KVM on people with accelerated configs will enjoy some SERIOUS competition to the IBM Mainframe monopoly!
