So LXC itself doesn't really have a definition for valid names, however since the name is typically used for the container's hostname, you should stick to what's considered a valid hostname on Linux. There's a POSIX RFC for that but IIRC it's basically 64 chars ASCII. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
