Comment 3 for bug 1565759

What I've discovered is asymmetrical network bridge configuration on nodes:

controller:
root@node-2:~# cat /etc/astute.yaml | grep enp0s5
    enp0s5:
  - {action: add-port, bridge: br-mgmt, name: enp0s5}

compute:
root@node-1:~# cat /etc/astute.yaml | grep enp0s5
    enp0s5:
  - {action: add-port, bridge: br-storage, name: enp0s5}

If I manually assign enp0s5 to br-mgmt ntpdate starts to work.

The test provisions nodes one by one using separate fuel cli commands. It might be that astule.yaml was mutated between these steps.
