Ah, ok. Sorry I misunderstood your question. This is not yet supported because there is a missing feature in the kernel. Hopefully, the kernel modification providing this functionality is ready and the author said he will submit it this week or next week, so that will be possible in a near future. This feature is very important because it allows build a set of scripts to facilitate container management from the outside like shutdown, netstat, etc ... If you wish to experiment this feature, it is available at: http://lxc.sourceforge.net/patches/linux/ and the command using it is lxc-attach, which is already available with the 0.7.2 version. At this point, it's experimental but very usable. I will be happy to have feedbacks ;) Thanks -- Daniel ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Lxc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/lxc-users
