If the user requests a mount for /run, this may hide any existing mounts that are lower down in /run. The result is that the container still sees the mounts in /proc/mounts, but cannot access them sh-4.2# df df: '/run/user/501/gvfs': No such file or directory df: '/run/media/berrange/LIVE': No such file or directory df: '/run/media/berrange/SecureDiskA1': No such file or directory df: '/run/libvirt/lxc/sandbox': No such file or directory Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_t500wlan-lv_root 151476396 135390200 8384900 95% / tmpfs 1970888 3204 1967684 1% /run /dev/sda1 194241 155940 28061 85% /boot devfs 64 0 64 0% /dev tmpfs 64 0 64 0% /sys/fs/cgroup tmpfs 1970888 1200 1969688 1% /etc/libvirt-sandbox/scratch Before mounting any filesystem at a particular location, we must recursively unmount anything at or below the target mount point Signed-off-by: Daniel P.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
