How are you cloning it? Might be some issue with SSH vs HTTPS.

You're running with the wrong qemu machine - the generic 'qemuarm' machine
won't work for the images the build produces. You need to use one of the
BMC-specific machines instead. Note that OpenBMC doesn't properly
integrate into the runqemu scripts, and you're often better served by invoking
it manually or (and!) sending a patch to make runqemu work properly.

We have some info on running qemu manually in the cheatsheet in the docs
repo:

https://github.com/openbmc/docs/blob/master/cheatsheet.md#using-qemu

Hope that helps,
