13795	Linux host freezes when starting VirtualBox VM with bridged network adapter and running docker container => Fixed in SVN	briceo		"Here is the environment setup:
Host: Ubuntu 14.04
VirtualBox: 4.3.20 r96996 (I've tested with 4.3.21 beta also)
Docker: 1.4.1 build 5bc2ff8 (I've tested with docker 1.2.0 also)

When trying to run a VirtualBox VM  with a bridged network adapter (guest OS doesn't seem to matter, as I've not even gotten to the point where the guest can be installed), and  there is a docker container already running, the host system freezes (completely locks up, and the only solution is to hit the reset button).

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
