Here's how I've been trying to debug it further: 1. Generate a VM image of our GNOME desktop template: ./pre-inst-env guix system image --image-type=efi-raw gnu/system/examples/desktop.tmpl (note that to boot it you'll have to select the EFI firmware, and you'll probably want bug#77110 applied to make this easier) 2. Copy it somewhere, e.g. /tmp/guix-gnome-desktop.raw 3. Make it writable: chmod +w /tmp/guix-home-desktop.raw 4. Install a new VM from this image in virt-manager. In my case I've named it 'guix-gnome-desktop'. Make sure to turn on 3D acceleration by selecting the virtio driver for the video device, checking '3D acceleration' (otherwise, virtualized GNOME is barely usable and frequently hangs for long bouts of time) 5. Add a CDROM storage device (SATA) via the virt-manager GUI 6. Start the VM, the fun can start! 7. Find the path to the CDROM drive via: --8<---------------cut here---------------start------------->8--- virsh -c qemu:///system domblklist guix-gnome-desktop Target Source -------------------------------------- vda /tmp/guix-gnome-desktop.raw sda - --8<---------------cut here---------------end--------------->8--- As you can see the device name of the CDROM in my case is 'sda'. That can also be seen in the XML of the device in the virt-manager GUI. We'll now insert a virtual CDROM via virsh: --8<---------------cut here---------------start------------->8--- virsh -c qemu:///system change-media guix-gnome-desktop sda \ --inject path/to/your-sample.iso --8<---------------cut here---------------end--------------->8--- To eject: --8<---------------cut here---------------start------------->8--- virsh -c qemu:///system change-media guix-gnome-desktop sda --eject --8<---------------cut here---------------end--------------->8--- We can now debug this issue efficiently and without having an actual CDROM drive. Except that currently 'udevadm monitor' doesn't seem to print anything. Hm. Perhaps that's part of the problem? Or my expectations of udevadm are wrong. -- Thanks, Maxim
