When using OpenStack Nova and Neutron Networking, virtual machines are intermittently unable to connect to the network.
Issue
- On compute nodes, inbound network connectivity to Nova-managed virtual machines via their floating ip address -- and outbound connectivity from the virtual machines to addresses outside of their private network -- was intermittently unavailable.
- Restarting OpenStack services may temporarily alleviate the problem
Environment
- Red Hat Enterprise Linux OpenStack Platform
