Hi Wei,

I have responded on the issue itself.  Adding a few extra notes here.

First thing is `--vt-machine-type`.  While s390-ccw-kvmibm-1.1.1 may be 
a valid machine type from qemu's perspective (qemu --machine help), they 
are not valid (as in present in upstream) avocado machine types.

Unfortunately, there's no standard way to check the valid Avocado 
machine types.  I created a card to tackle this:

https://trello.com/c/aumjDJde/715-avocado-vt-add-vt-list-machines

For now, you can look at avocado-vt/shared/cfg/machines.cfg

See the machines.cfg reference here and the other reference on the 
github issue.
