For seclabel remembering we need to have XATTRs and a special namespace that is accessibly to CAP_SYS_ADMIN only (we don't want regular users to trick us into restoring to a different label). And what qemusecuritytest does is it checks whether we have not left any path behind with XATTRs or not restored to original seclabel after setAll + restoreAll round trip. But it can hardly do so if ran on a platform where there's no XATTR namespace we can use.
