    LXC container memory configuration

    Could somebody elaborate on how to configure the LXC memory settings properly? The UI allows me to set the memory limit of my container to e.g 1024MB and 0MB for swap. According to the documentation this would be wrong: Is the UI missing a sanity check or am i misinterpreting the documentation?
