That could be really nice ... Thanks. I have seen openQRM, but looks overkill for what I want. A simple menu driven interface over ssh would have been ideal. libvirt has pretty good support for LXC. Maybe virsh or the ncurses-like/based UI that recently got committed to virt-manager is something along the lines of what you're looking for? -- Jon Nordby - www.jonnor.com -- What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d ___ Lxc-users mailing list Lxc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-users

I recently realized that since ALSA does mixing in userspace one probably cannot share an alsa device between containers (or host+container) since they do not share userspace. OSSv4 on the other hand does mixing in the kernel and might just-work. If not, once could use PulseAudio to share one soundcard with several containers. -- Regards Jon Nordby - www.jonnor.com -- Beautiful is writing same markup.

Re: [Lxc-users] starting a container causes Xorg to consume 100% cpu

Are there any work-arounds to avoid this behaviour? I can reproduce this issue on a container (with separate rootfs) which does not even have pts, tty or networking set up. gettys in the container are commented out, of course. This is on 2.6.34 with lxc 0.7.0 It also leaves me unable to switch ttys in the host. Shutting down the container does not fix the problem, I have to kill X for it to go back to normal. -- Regards Jon Nordby - www.jonnor.com -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
