Hi, me again. I regularly try new distros with gnome-boxes (it is enough for a first glance), but on Leap 42.2 there is no iso I could start as a virtual machine. Here is the console output of gnome-boxes (currently I only have a netinstall iso of debian testing...): (gnome-boxes:3238): Boxes-CRITICAL **: libvirt-machine.vala:143: Failed to fetch configuration for domain 'boxes-unknown': Unable to get domain XML config: Domain not fo und: no domain with matching uuid 'bd9ed773-47e2-4798-b462- e160b121ff30' (boxes-unknown) (gnome-boxes:3238): Boxes-WARNING **: machine.vala:606: Failed to start debian-stretch-DI-alpha8-amd64-netinst: Unable to start domain: internal error: process exited wh ile connecting to monitor: uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x6.0x1 -device ich9- usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x6.0x2 -device vir tio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -device usb- ccid,id=ccid0 -drive file=/home/tibor/.local/share/gnome- boxes/images/boxes-unknown,format=qcow2,if=none, id=drive-ide0-0-0,cache=writeback -device ide- hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=2 -drive file=/home/tibor/Downloads/debian-stretch-DI-alpha8 -amd64-netinst.iso,format=raw,if=none,id=drive-ide0-1-0,readonly=on -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1- 0,bootindex=1 -netdev user,id=hostnet0  -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:e4:05:3f,bus=pci.0,addr=0x 3 -chardev spicevmc,id=charsmartcard0,name=smartcard -device ccid-card- passthru,chardev=c harsmartcard0,id=smartcard0,bus=ccid0.0 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev spicevmc,id=charchannel0,name=vda Since I am only a user of boxes, I do not have any idea what this means.
