Start vm without specified root dir has same issue *** Bug 2000983 has been marked as a duplicate of this bug. *** *** Bug 2016264 has been marked as a duplicate of this bug. *** Upstream patch: https://listman.redhat.com/archives/libvir-list/2023-March/238834.html Given the disclaimer in virt-qemu-run's man page: NOTE: this tool is currently considered experimental. Its usage and behaviour is still subject to change in future libvirt re‐ leases. For further information on its usage consult the QEMU driver documentation. I don't think we care about it much. But the fix seemed trivial enough. commit 8c8cda2c9a94c63917e859ed83593dc4e28b0644
