Howdy,
I am playing around with asterisk within an LXC container on Ubuntu
11.04. I have asterisk (1.4.42) running fine, but want access to
dahdi_dummy for timing (meetme). I have dahdi installed on the "host",
and dahdi_dummy is loaded:
root at astnorth:/# ls -ltr /dev/dahdi
total 0
crw-rw---- 1 root root 196, 250 2011-06-08 13:59 transcode
crw-rw---- 1 root root 196, 253 2011-06-08 13:59 timer
crw-rw---- 1 root root 196, 255 2011-06-08 13:59 pseudo
crw-rw---- 1 root root 196, 0 2011-06-08 13:59 ctl
crw-rw---- 1 root root 196, 254 2011-06-08 13:59 channel
root at astnorth:/#
But in the container I don't see them:
root at artha:/# ls -ltr /dev/dahdi
total 0
even though /dev/dahdi showed up as soon as I loaded the kernel module
in
the host.
Maybe this is more a question for an LXC list, but I noted that a few
people had played with this (asterisk in LXC) and wondered if anyone
managed to get dahdi_dummy shared across their containers...
Maybe you need to enable the guest to access those devices?
In the lxc guest conf file, you should probably have omething like:
lxc.cgroup.devices.allow = c 196:0 rwm # /dev/dahdi/ctl
lxc.cgroup.devices.allow = c 196:253 rwm # /dev/dahdi/timer
lxc.cgroup.devices.allow = c 196:254 rwm # /dev/dahdi/channel
lxc.cgroup.devices.allow = c 196:255 rwm # /dev/dahdi/pseudo
# For the record: you don't probably don't need the following one:
#lxc.cgroup.devices.allow = c 196:250 rwm # /dev/dahdi/transcode
That was indeed the ticket - I now have dahdi shared across all the
containers. Now going to run some meetme test ;)
Thanks Tzafrir!
