DVD drive not accessible in KVMs

Hi,

Thanks for the prompt response and support, Ive set up Windows 2012 std Edtn and a Cent OS 6.2 client in HS 23 blade. I have to install some softwares in Windows server, so I mounted the DVD drive to this blade and assigned the physical CD/DVD drive in proxmox to windows but I couldn't see the contents in the DVD in windows server. I couldn't understand where it went wrong any inputs to fix this will be highly appreciated. Thanks in advance.
