[Openstack] error creating instance

You wouldn't want to configure br-ex on a compute host. br-ex is the bridge that connects a network node to the outside provider
network.
If you wanted to use VLAN based tenant networks, then you would have to configure a new, separate bridge. But that is not your case.
Please also make sure that GRE traffic is allowed between network and compute nodes.
iptables -I INPUT 2 -p gre -s <your tunnel network CIDR> -d <your tunnel network CIDR> -j ACCEPT
or equivalent.
