Yeah, I guess I was running the old tests. With the new tests I now have:

tools/testing/selftests/ftrace# ./ftracetest test.d/remotes/
=== Ftrace unit tests ===
[1] Test trace remote buffer size	[PASS]
[2] Test hypervisor trace buffer size	[UNSUPPORTED]
[3] Test hypervisor trace buffer reset	[UNSUPPORTED]
[4] Test hypervisor consuming trace read	[UNSUPPORTED]
[5] Test hypervisor non-consuming trace read	[UNSUPPORTED]
[6] Test hypervisor trace buffer unloading	[UNSUPPORTED]
[7] Test trace remote reset	[PASS]
[8] Test trace remote consuming read	[PASS]
[9] Test trace remote non-consuming read	[PASS]
