[libvirt] [PATCH] LXC: create directory /dev/shm automatically
Now we mount /dev as tmpfs and haven't created directory
/dev/shm,so the glibc api such as shm_open/sem_open will
create files under dir /dev.(since /dev is mounted as tmpfs)
Through these api still useable in container,but this cause
directory /dev looks a little chaos.
This patch create directory /dev/shm automatically,the files
created by shm_open/sem_open will stay in this directroy.
