[lxc-users] LXCFS install issue

[Rajasekar Darapuram]

After more research..this is what I found
I have 2 test machines...will get hardware details for comaprision (from
our hardware team)..
LXCFS works fine on 1 machine, while i get the issue on other machine (same
ISO, same LXC, LXCFS debs etc)..
then I installed the latest Ubuntu 14.04.2 iso (which has latest kernel
etc) on the machine which was failing and I still get the same issue....

fuse error and proc not mounted (when i attach to the containers)..Is there
any hardware requirements for FUSE or LXCFS?

One weird thing is on my local laptop, I used to have LXC/LXCFS
running..now when i installed latest lxc/lxcfs and start a container I get
this error on my local laptop

root at Local-Raj:/home/raj# lxc-start -n today2
lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 346 To get more details, run the container in
foreground mode.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by
setting the --logfile and --logpriority options.
