Hi there! After upgrading centos 6.5 to 6.6 I cannot create new instance. I get the following error in scheduler.log:

... which says completely nothing. On compute0 node:

This is really strange. I can run my existing instances however I cannot connect them and from console I cannot ping between them (IP address is fine). I was trying to reinstall openvswitch and recreating br-int but it is not giving me any results :( Any help will be appreciated.
