9. Common troubleshooting
- VM won't boot: check qemu logs, console output, ensure virtio drivers if guest expects them.
- Networking issues: confirm guest network interface names, cloud-init network config, libvirt network type.
- Disk errors after conversion/resize: run fsck inside guest or mount raw image loopback: losetup + kpartx, then fsck.
- virt-filesystems -a image.qcow2 --all --long
- guestfish -a image.qcow2 -i : list-filesystems, inspect fstab, /etc/release
1. The Boot Structure:
