After reading a bit about similar errors (
https://www.redhat.com/archives/rhos-list/2013-May/msg00067.html) i
remembered that i have an older nova version running in one of the
compute-nodes. I shutted down this older node and restarted nova-* on the
new one and everything started working just fine. I haven't tried updating
the server because i have to reinstall it anyway.
