Is it possible to access /dev/hdc from a VE?

One of my environments (the central backup server) needs to be able to 
burn collections of backups to a dvd.

I tried to solve this by creating the device in the VE (mknod -m 660 
/dev/hdc b 22 0) but I still get a permission error;

It tells me:  unable to open64("/dev/hdc",O_RDONLY): Permission denied

Ir all works fine outside the VE.

I suspect this may be something I can't do in a VE, but I thought I'd 
ask :-)
