This tends to hang in the replay phase near the end of the trace due to a missing event, so it is marked flaky. spapr-vscsi IO is extremely slow when running in record-replay modes, particularly when driven by SLOF. This causes tests to time-out even after an hour, so this uses guestfish to extract the kernel and initrd and boot them directly.
