Jul 12 09:34:04 cent7 systemd[1]: Unit docker.service entered failed state.
Expected to see docker package install correctly by default and allow using systemd to startup docker on the machine.
This is running inside a fresh install of Centos 7.1 inside virtualbox. Docker 1.7.1 works with no issue.

@jfrazelle You can ignore the bridge modprobe failure message. That will be printed if the bridge module is compiled into the kernel rather than as a module. We should rather check the docker logs.
@squeaky-pl One more thing that you can do is send
SIGUSR1to docker daemon and if docker daemon is anywhere near sane state it should dump the stack traces of all the go routines inside docker daemon. You have to start the daemon in debug mode though. If you can collect those traces and post it here that would be helpful.@abierbaum @squeaky-pl @KalleDK As a quick check, can you enable debugs (-D) and restart the docker-service ?
