On i386 hosts, qemu errors if the memory size is > 2047 MB

Installed maas-test 0.1+bzr58+81+8~ppa0~ubuntu13.10.1 on a system with a fresh saucy install.

I then tried to run it in interactive mode but that failed because --interactive is apparently not a recognized argument.

So I attempted to run manually like so:

maas-test --bmc-ip 192.168.0.5 --bmc-username <username> --bmc-password <password> eth0

and got the following output including the traceback:
