     This one sounds like you have have run out of vnd device nodes.
By default, only four vnds are created.  You need to cd /dev, and
./MAKEDEV vnd4 vnd5 vnd6 vnd7 ...  This is a common problem when you
are using virtual disks with Xen and a have a bunch of clients or
multiple disks per client (that includes CD images).
