Package: installation-reports Severity: normal This issue is already fixed in weekly builds as of 2023-02-09, but I'm reporting it as errata for the alpha 1 milestone. Boot method: virtual CD Image version: debian-bookworm-DI-alpha1-amd64-netinst.iso Machine: virt-manager "Debian testing" qemu VM presets Partitions: none yet at the point where I encountered the error Base System Installation Checklist: [O] = OK, [E] = Error (please elaborate below), [ ] = didn't try it Initial boot: [E] Overall install: [ ] Comments/Problems: I tried doing a fresh install from bookworm d-i alpha 1 netinst media, in a qemu VM under virt-manager installed from unstable, using virt-manager's "Debian testing" presets: * virtio HDD * SATA CD-ROM with the debian-bookworm-DI-alpha1-amd64-netinst.iso image * virtio GPU, connected to the virt-manager GUI using the Spice protocol * virtio network card, which I connected to the network bridge created by libvirt-daemon-system To reproduce ============ Full virt-manager XML suitable for passing to `virsh define debian12-testinstall.xml` is attached (please adjust the paths that say EDITME as required for your system), or you can use the virt-manager GUI and select "Debian testing" as the OS to be installed: * File -> New Virtual Machine * Connection: QEMU/KVM User session * Local install media * Architecture: x86_64 * ISO or CDROM install media: debian-bookworm-DI-alpha1-amd64-netinst.iso * Choose the OS you are installing: if automatic detection does not pick "Debian testing", uncheck "Automatically detect" and select Debian testing * Memory and CPUs: whatever will fit on your hardware, I chose 4096M and 3 vCPUs * Storage: whatever you prefer, I chose to create a new 20G qcow2 image At the netinst CD's grub prompt I selected the graphical installer. Expected result =============== Xorg starts and I can proceed through the graphical installer. Actual result ============= Xorg restarts in a loop with this message: > Fatal server error: > (EE) no screens found(EE) Workaround ========== I tried again with the text-mode installer. This started successfully. I chose to install the Xfce desktop environment instead of the default GNOME (to make sure I would still be using Xorg). When I booted the installed system, the display manager (lightdm?) started successfully and I was able to log in to an Xfce session. Fix === When I used the weekly build from https://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/ dated 2023-02-09, the graphical installer started successfully. Presumably the necessary modules to detect or use a virtio GPU were missing from the alpha 1 milestone netinst image but were added to subsequent images. smcv
