Multiple test suites
We currently have one test suite that starts from the ISO image, installs the OS, and runs 1 test at a time in sequence. This doesn't scale beyond ~5 minutes worth of tests because cycle time to actually work on the tests becomes too high. We are already at that limit.
It's possible to store the HDD after the install phase, using STORE_HDD_1=1
config setting. We could then have multiple test suites running against the freshly installed HDD.
