Populate /dev/std{in,out,err} symlinks in LXC containers
Some applications expect /dev/std{in,out,err} to exist. Populate
them during container startup as symlinks to /proc/self/fd

Populate > them during container startup as symlinks to /proc/self/fd It works fine with libvirt-0.9.10-1.el6 now. I can reproduce this bug in RHEL7 libvirt-0.9.7-3.el7.x86_64 qemu-kvm-0.15.1-3.2.el7.x86_64 add comment to track this bug ,we will test it again after RHEL7 libvirt upgrade to 0.9.10 from 0.9.7 .
