I can respin the pull request to drop the test and/or give it a longer timeout so it is less likely to be flaky in CI. [1] https://lists.gnu.org/archive/html/qemu-devel/2026-11/msg01941.html Markus, what are your thoughts on a QMP addition this late into 11.2 so that the test in 2/8 can be stable? I'm torn on whether the NBD bug in 1/8 is severe enough to need to go in 11.2.0 proper, or whether the bug is weak enough that it is safer to wait until 11.2.1 via the qemu-stable process. Patches 3-8 fix CVEs, so they definitely belong in 11.2. -- Eric Blake, Principal Software Engineer Red Hat, Inc. Virtualization: qemu.org | libguestfs.org
