Bug#1111240: cloud.debian.org: generic trixie amd64 qcow2 image unable to boot
Package: cloud.debian.org
User: cloud.debian.org@packages.debian.orgUsertags: image
Hi,
I’m deploying cloud images on a Libvirt/QEMU/KVM hypervisor using Ansible. After trixie hit stable, I replaced the bookworm image with a trixie one, but I am unable to get it to boot. The only change in the deployment process was switching from debian-12-generic-amd64.qcow2 to debian-13-generic-amd64.qcow2.
The process seems to hang during boot, and no errors are printed anywhere. I’m able to connect to the VM using virsh console, but I only see the first line "Booting Debian GNU/Linux" and nothing further happens.
QEMU log:
