I've pushed a new tool called "virt-log" upstream, so you can now just do: virt-log -d Guest or: virt-log -a disk.img It will automatically fetch the journal or traditional syslog file as appropriate, and we can add Windows support in future. Unfortunately the journal_* API calls are rather slow because they have to fetch each single line from the journal. So there's some work to be done to make that fast.
