At the time, it was envisioned that setting QGA_TEST_SIDE_EFFECTING in the environment could cover a few more commands, while noting the potential danger of those side effects running in the host. But this has NEVER been tested: if you enable the environment variable, the test WILL fail. One obvious reason: if you are not running as root, you'll probably get a permission failure when trying to freeze the file systems, or when changing system time. Less obvious: if you run the test as root (wow, you're brave), you could end up hanging if the test tries to log things to a temporarily frozen filesystem. But the cutest reason of all: if you get past the above hurdles, the test uses invalid JSON in test_qga_fstrim() (missing '' around the dictionary key 'minimum'), and will thus fail an assertion in qmp_fd(). Rather than leave this untested time-bomb in place, rip it out. Hopefully, as originally envisioned, we can find an opportunity to test an actual sandboxed guest where the guest-agent has full permissions and will not unduly affect the host running the test - if so, 'git revert' can be used if desired, for salvaging any useful parts of this attempt.
