I was trying to deploy a instance from a image and i'm getting below error. I have no clue what is wrong with this centos7 image.

Error: Failed to perform requested operation on instance "centos7", the instance has an error status: Please try again later [Error: Build of instance caeb2aca-2225-42c3-a780-c678c7b5b30d aborted: Block Device Mapping is Invalid.].

How did you launch that instance? What parameters did you specify? Do other images lead to this error? Do you get the error when trying later? You should have more information in the nova-compute log, in particular if you enable debug logging.

I'm launching instance from Horizon and specified all required parameters which is been required when we deployed from Horizon. Yes all images leads to this error except cirros. I get this error every time i deploy instance. Didn't found anything in nova-compute.log

On newton release try via Nova CLI (for instance) :-

$ . keystonerc_demo
$ nova boot --flavor 2 --key-name oskey021817  --image image-id --nic net-id=private-network-id  VM1

See for Neutron CLI http://dbaxps.blogspot.com/2017/01/rd... starting with lines

  [ root@overcloud-controller-0 ~]# nova list

Never experienced problems with assigning FIP on RDO Newton. Try via neutron CLI
One neutron commands

neutron port-list --device-id  server-id
neutron floatingip-create ext-net
neutron floatingip-associate \
fip-id  port-id

should return error . Then check logs.

Same here, works from CLI, but not from Horizon
