I've reproduced this bug  on my vcenter's machine with configuration, which is described below:

api: '1.0'

auth_required: true

ostf_sha: 4dcd99cc4bfa19f52d4b87ed321eb84ff03844da
production: docker
release: '5.1'

on vcenter machine 172.18.170.88:
1. Create new environment (CentOS, simple mode)
     Network:  Nova Network Flat DHCP

     setting for vcenter creation:
                    VCENTER_IP='172.16.0.254'
                    <email address hidden>'
                    VCENTER_PASSWORD='Qwer!1234'
                    VCENTER_CLUSTERS='Cluster1'  

2. Add 2 nodes with roles: 1 controller and 1 cinder (as storage type - VMDK)
3.  Make deploy of environment
4.  Verify network connectivity
5.  Run ostf
