3c4fb177237a115c85c439422f08316e4b8d0d74 tests/qtest: make more migration pre-copy scenarios run non-live
There are 27 pre-copy live migration scenarios being tested. In all of
these we force non-convergence and run for one iteration, then let it
converge and wait for completion during the second (or following)
iterations. At 3 mbps bandwidth limit the first iteration takes a very
long time (~30 seconds).
While it is important to test the migration passes and convergence
logic, it is overkill to do this for all 27 pre-copy scenarios. The
TLS migration scenarios in particular are merely exercising different
code paths during connection establishment.
To optimize time taken, switch most of the test scenarios to run
non-live (ie guest CPUs paused) with no bandwidth limits. This gives
a massive speed up for most of the test scenarios.
For test coverage the following scenarios are unchanged
* Precopy with UNIX sockets
* Precopy with UNIX sockets and dirty ring tracking
* Precopy with XBZRLE
* Precopy with UNIX compress
* Precopy with UNIX compress (nowait)
* Precopy with multifd
On a test machine this reduces execution time from 13 minutes to
8 minutes.
