virsh dumpxml result from virt-install Edit (4.6 KiB, application/xml)

able to reproduce with image created with

```
virt-install --connect qemu:///session \
--name cloudinit-test \
--memory 2048 \
--disk /home/achasen/tmp/focal.img,device=disk,bus=virtio \
--os-type linux \
--os-variant ubuntu20.04 \
--virt-type kvm \
--graphics none \
--network bridge=virbr0,model=virtio \
--import \
--disk /tmp/test.iso,device=cdrom,bus=sata
```

/run/cloud-init/cloud-init-generator.log indicated run around 0.69s:

```
No ds found [mode=search, notfound=disabled]. Disabled cloud-init [1]
[up 0.69s] returning 1
```

jornalctl shows things like "Starting Network Service" before sr0 is in the log (which makes me think the sr0 is delayed). I didn't find anything in journalctl output related to the generator.
