Description Pablo Iranzo Gómez 2016-02-17 12:48:11 UTC 
Description of problem:

- During the overcloud deployment,  we observed  many packets lost betwen the Director (undercloud) and the node to deploy.  Then, our deployment failed.
Here attached, the log from  one of the failed deployed nodes
- After blocking the VRRP traffic (on the Director)  thanks to the commands below, we were able to successfully deploy the overcloud
iptables -I OUTPUT -p vrrp -o br-ctlplane -j REJECT 
iptables -I INPUT -p vrrp -i br-ctlplane -j REJECT 

Our environment: 
- RHEL OSP Director 7.2   (on a RHEL 7.2)  deployed VMware  VM
- All the overcloud VM  are deployed with a RHEL 7.2
VMware infrastructure:
-  VMware vCenter Server Version 5.5.0 Build 2646482
-  Our cluster constains 2 ESX   with  VMware ESXi 5.5.0 build-2403361   Update 2
