If I start the VirtualBox VM first (with a bridged adapter), and then start the docker container, the host does not freeze. Additionally, If I change the VirtualBox VM network from bridged to NAT, then the host does not freeze (assuming the docker container was started first, and then the VM). I have not seen any kernel panics, and upon reboot, there is nothing in the logs to indicate an error happened.",defect,closed,network,VirtualBox 4.3.20,fixed,bridged network docker,,all,Linux
