Hi Laszlo, I think using the QEMU feature to map a path from the host as a FAT formatted driver has value to provision QEMU with a set of target tests to run. I agree there is no persistent storage of writes to this type of drive. I believe writes are supported if file state is needed during the single boot of QEMU.
In order to get test results out of QEMU back to the host, I was considering the use of consoles mapped as named pipes and send all test results out the console device and the host can parse the logs. I have not had good experiences trying to build virtual disks, provision them, map them into QEMU, and remount from host to collect test results. Slow operations and cumbersome to mount/unmount from the host (at least from Windows environments).
