Add usbdevice to libvirt by modifying cgroup

By | 2013年10月31日

CGROUP means Control group.
In my case, usb-redir works fine while usb-host not.

Just do it

Add fine control list

Review the rules to libvirt, and leave all the character device to it

devices.deny/allow is something like end-point.

About hierarchy

A child will not have more permission than its parent.
