No /dev/uinput and Upstart cannot be contacted

When trying to run tests with --setup-commands ubuntu-touch-session, it seems that upstart cannot be contacted, and there is no /dev/uinput available, when trying to start the click app for testing in autopilot:

adt-run --click-source . --click ../build-adt-run-ap-UbuntuSDK_for_amd64_GCC_ubuntu_sdk_14_10_utopic-Default/com.canonical.payui_15.01.last_amd64.click -U --apt-pocket proposed --setup-commands ubuntu-touch-session --- qemu ~/adt-vivid-amd64-cloud.img
