131 test modules sat next to the code they test; instances alone had
51 of them beside views.py and utils.py. They move into a
tests/ package per app, and the JavaScript checks into
webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py;
the empty generated stubs are removed.
Imports of the app's own modules become absolute, paths built from
__file__ go one level up, the live helper is instances.tests.livetest,
and coverage omits */tests/*. The suite discovers the same 960 tests as
before.
A VM that changes its memory faster than the network carries it does
not finish a live migration without auto converge (measured: a guest
rewriting about 1.2 GB/s did not finish in 90 s over an 8.5 Gbit/s
link, and finished in 16-18 s with it). Auto converge only slows the
VM's CPUs while the migration cannot keep up, so a calm VM is not
affected.
The migrate form ticks it for a running VM. The API already documented
it as on by default but read a left-out option as off; the serializer
now has the defaults (auto converge on, compress and unsafe off) for
JSON and form-encoded requests, and the schema shows them.
