[Lxc-users] what is the best way to make dvb devices available in a container
Hi, I'am experimenting with lxc and have successfully make the dvb devices from /dev/dvb/adapter0/* available to a container with the mount --bind option. But when I unload and load the drivers, the /dev/dvb of the container is empty, because during unloading the drivers the /dev/dvb directory of the host is removed and then during loading the drivers a new one is created. Is there a better way to make the dvb devices available in a container, so the devices will exist in the container as they were created in the host ? -- best regards Dieter -- I do not get viruses because I do not use MS software.

Can we see project plans or a todo list or something like these which gives us about the future features should come in next releases. I can't find something like this in a TODO file, open bug reports or a special page in sourceforge. Or do you suggest something to follow other than these. I'm about to start a project (https://github.com/bergerx/simplelxc#readme) for mainly laptop users to create and manage networking enabled test containers so simply which also setup initial networking for both lxc containers and host system. I would like to use networking as it should be and determine the project direction according to this or I should be in a position to re-implement some parts. I've talked implementing some ideas into debian lxc package Daniel Baumann mainy about a simple creation scenario without asking anything other than container name. Right now in ubuntu precise, it's lxc-create -t ubuntu -n p1 lxc-start -n p1 or lxc-create -t ubuntu-cloud -n p1 lxc-start -n p1 If you want to deploy a bunch of cloned images, you can lxc-create -t ubuntu -n plain -B lvm customize /dev/lxc/plain image if you like for i in `seq 1 20`; do lxc-clone -s -o plain -n p$i done The only things different in Ubuntu are that a lxcbr0 bridge gets installed by default (*1), and the release has been tweaked a bit so no changes are needed to run in a container. The first can't really be done in lxc.git (because it's distro-dependent), and the second is of course independent of lxc. -serge (*1) and if you don't specify a configuration file at creation time, a default one using lxcbr0 is used. -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ Lxc-users mailing list Lxc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-users
