[PATCH 0/4] Speed up migration tests

[Thomas Huth]

We are currently facing the problem that the "gcov-gprof" CI jobs
in the gitlab-CI are running way too long - which happens since
the migration-tests have been enabled there recently.

These patches now speed up the migration tests, so that the
CI job should be fine again.

This is how it looked like before my modifications:

 https://gitlab.com/thuth/qemu/-/jobs/2888957948#L46
 ...
 5/243 qemu:qtest+qtest-aarch64 / qtest-aarch64/migration-test  OK  1265.22s
 8/243 qemu:qtest+qtest-x86_64 / qtest-x86_64/migration-test    OK  1138.82s

And this is how it looks like after the patches have been applied:

 https://gitlab.com/thuth/qemu/-/jobs/2905108018#L48
 ...
 5/243 qemu:qtest+qtest-aarch64 / qtest-aarch64/migration-test  OK   251.14s
 8/243 qemu:qtest+qtest-x86_64 / qtest-x86_64/migration-test    OK   336.94s

That means the CI job is running ca. 30 minutes faster here now!
