Subject Re: IPTables on CentOS
Date Thu, 14 Feb 2013 02:42:10 GMT
Hey Noel, 

I had this issue too. This workaround did the job for me:

- stop cloud Agent service on KVM host
- execute iptables -F, ebtables -F on KVM host
- uninstall ebtables package on KVM host (I had to use --nodeps) 
- start cloud Agent service on KVM host
