That left only the actual disk+iso of fedora vs ubuntu cloudimg based qcow and that the boxes VM used userspace networking. Still the issue remained.
But I realized there is one more difference, the Boxes VM runs in user context while mine is a system level VM (qemu:///system) running the gl essentially headless until one connects to the local spice port. But the gnome boxes VM was having the UI up immediately connecting to it once available. So I defined the XML of the gnome-boxes VM in my qemu:///system libvirt context. This - as expected (I copied the files to /var/lib/libvirt/images and adapted the paths). This makes it work which is at least some lead to follow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815889 Title: qemu-system-x86_64 crashed with signal 31 in __pthread_setaffinity_new() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1815889/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
