The host is Windows 8 Pro and virtualization is done by Hyper-V which comes with Windows 8 Pro.
The quest os is Windows XP Pro SP3.
The XP is the only guest os, so that it is not mounted on any other guest os.
I want to access DVD drive to install application softwares, re-install OS, etc.
Edit: After posting the above I tried it again and found it working now. Believe me I tried many times before. Thanks everyone for trying to help me.
