Subject: [PATCH net-next 00/12] selftests/vsock: refactor and improve
 vmtest infrastructure

Hey all,

This patch series refactors the vsock selftest VM infrastructure to
improve test run times, reduce false-positives, improve logging
generally, and fix several bugs.

It also prepares for future tests which make heavy usage of these
refactored functions and have new requirements such as simultaneous QEMU
processes.

These patches were broken off from this prior series:
