Unfortunately it does regress. The system crashes on boot. So this needs to
be addressed first.

You can reproduce via 'oe-selftest -r
runtime_test.TestImage.test_testimage_virgl_gtk'.

You probably should create an arm-specific qemuboot config file that suits
your usecase rather than try to tweak runqemu script to change settings
after the fact.
