[libvirt] Mounting /dev/tty* to the Virtual Domain.

Hi All, How to mount /dev/tty* files to the Virtual Domain '/dev' directory. Some of the packages are not installing in the Virtual Domain, due the absence of these files in the /dev directory. In the rootfs directory, '/dev' directory shows lot of files, but after mounting to the rootfs to '/' directory of Virtual Domain, some tty* files are missing. How to mount those tty files to the Virtual Domain? Regards, Srikanth.
