      This is a follow up patch of commit f9ce7dad, it modifies all
      the files which declare the copyright like "See COPYING.LIB for
      the License of this software" to use the detailed/consistent one.
      
      And deserts the outdated comments like:
      
       * libvirt-qemu.h:
       * Summary: qemu specific interfaces
       * Description: Provides the interfaces of the libvirt library to handle
       *              qemu specific methods
       *
       * Copy:  Copyright (C) 2010, 2012 Red Hat, Inc.
      
      Uses the more compact style like:

      Remount cgroups controllers after setting up new /sys in LXC · a8c0b2fe
      Daniel P. Berrange 提交于
      Normal practice is for cgroups controllers to be mounted at
      /sys/fs/cgroup. When setting up a container, /sys is mounted
      with a new sysfs instance, thus we must re-mount all the
      cgroups controllers. The complexity is that we must mount
      them in the same layout as the host OS. ie if 'cpu' and 'cpuacct'
      were mounted at the same location in the host we must preserve
      this in the container. Also if any controllers are co-located
      we must setup symlinks from the individual controller name to
      the co-located mount-point

      cpustats: collect VM user and sys times · 0d0b4098

      As documented in linux.git/Documentation/cgroups/cpuacct.txt,
      cpuacct.stat returns user and system time in ticks (the same
      unit used in times(2)).  It would be a bit nicer if it were like
      getrusage(2) and reported timeval contents, or like cpuacct.usage
      and in nanoseconds, but we can't be picky.

      cgroup: allow fine-tuning of device ACL permissions · 5564c575
      Eric Blake 提交于
      Adding audit points showed that we were granting too much privilege
      to qemu; it should not need any mknod rights to recreate any
      devices.  On the other hand, lxc should have all device privileges.
      The solution is adding a flag parameter.
      
      This also lets us restrict write access to read-only disks.

      * src/util/cgroup.c (virCgroupAllowDevice)

      qemu_driver: add virCgroupMounted · 41b2cee2
      Lai Jiangshan 提交于
      When we mount any cgroup without "-o devices", we will fail to start vms:
      
      error: Failed to start domain vm1
      error: Unable to deny all devices for vm1: No such file or directory
      
      When we mount any cgroup without "-o cpu", we will fail to get schedinfo:
      Scheduler      : posix
      error: unable to get cpu shares tunable: No such file or directory
      
      We should only use the cgroup controllers which are mounted on host.
      So I add virCgroupMounted() for qemuCgroupControllerActive()
