From 73439e9284f4c7101721ee081d5ca6249d284ed0 Mon Sep 17 00:00:00 2001 Message-Id: <73439e9284f4c7101721ee081d5ca6249d284ed0@dist-git> From: Michal Privoznik Date: Mon, 21 Mar 2022 17:10:15 +0100 Subject: [PATCH] qemu_command: Generate prealloc-threads property Let's generate prealloc-threads property onto the cmd line if domain configuration requests so. Signed-off-by: Michal Privoznik Reviewed-by: Martin Kletzander (cherry picked from commit b8d6ecc70c8a8e9c90bab48b6829b42d8b77c748) Conflicts: tests/qemuxml2argvdata/memfd-memory-numa.x86_64-latest.args: Upstream has moved some cmd line arguments (v8.0.0-260-gaf23241cfe) but that is not backported.
