Python shim over QEMU to startup BMC
In case anyone wants to run a/some Supermicro firmware image under QEMU… here’s a short script that sets some network features (thanks to binarly for figuring out the hard stuff!) It still crashes and burns because I didn’t use the gdb trick they mention in the URL, but you can now talk to the BMC…
