hello all

i had try rdo Newton with allinone setup after that i had add more compute nodes with answer file. i had used bridge network br-ex to acces external network i can create instance in compute node 1 which was in (allinone) with network working using br-ex without problems but all other compute nodes i got error

Error: Failed to perform requested operation on instance "CN5", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].
