From b1937fd1eb8360d0dc0abb0a8da221d8edce3733 Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Tue, 4 Mar 2025 23:03:36 +0100 Subject: migration: Add thread pool of optional load threads MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some drivers might want to make use of auxiliary helper threads during VM state loading, for example to make sure that their blocking (sync) I/O operations don't block the rest of the migration process. Add a migration core managed thread pool to facilitate this use case. The migration core will wait for these threads to finish before (re)starting the VM at destination.
