You previously mentioned you're using package 2.5.5-0.fc17. It looks like you have a typo, so please resend the exact package of ovirt-node you're using. Also - Where did you get the package from? We'd like to try and reproduce here.
Did you make any changes to mount so that /var is now Read Only? Please send us the output for the mount command on your system. Please remember to reply-to-all next time(s)...
