Hi Steffen, please don't add any new function wrappers around global_qtest anymore. We recently already started to get rid of this global variable in a couple of places (see https://git.qemu.org/?p=qemu.git;a=commitdiff;h=db57d7a3c284db2315d9 and preceding commits for example), since it causes trouble in tests that want to run multiple QEMU instances at once (in migration tests for example). It would be good to have new code clean for this right from the start. Thanks, Thomas
