The main issue I see is that the VM run command has actually failed
due to libvirt no accepting /dev/urandom as RNG source[1]. This was
done as engine patch and according to git log, posted around Mon Nov
28. Also adding Jakub - this should either not happen from engine's
point of view or the lago host is outdated.
