It's not obvious that something named __init__.py actually houses important code that isn't relevant to python packaging glue. Move the QEMUMachine and related error classes out into their own module. Adjust users to the new import location.

# 1. use small image size

# 2. use raw format (not qcow2)

# 3. drop kvm and use iotests.VM() (maybe, because of qtest) (however, it still
|

# reproduces, if just drop kvm, but gdb failed to produce full backtraces
|

# for me)

# 4. add iothread
