I am working on a fresh VM delivered by Host Europe that matches the description on
https://docs.docker.com/installation/ubuntulinux/#ubuntu-trusty-1404-lts-64-bit
(so Ubuntu Trusty 14.04 (LTS) (64-bit), 3.13.0 Linux kernel).
After installing the docker.io package docker ps fails with
"Cannot connect to the Docker daemon. Is 'docker -d' running on this host?"
When running docker -d I get:
INFO[0000] +job serveapi(unix:///var/run/docker.sock)
INFO[0000] +job init_networkdriver()
inappropriate ioctl for device
INFO[0000] -job init_networkdriver() = ERR (1)
FATA[0000] inappropriate ioctl for device
Apparently this error happens as well when the docker service tries to start via upstart. I also tried it with the latest docker package according to "Docker-maintained Package Installation" in the above-mentioned description.
Here is the more detailed ouptput using docker -D -d:
INFO[0000] +job serveapi(unix:///var/run/docker.sock)
DEBU[0000] libdevmapper(3): ioctl/libdm-iface.c:363 (-1) /dev/mapper/control: open failed: Operation not permitted

Ideas anybody? Thanks in advance. (Seems like a "deadend" to me after lots of successfull "dockerizing" on local VMs.)
