It's interesting. So, how you exactly trying to read CD inside linux guest ?
--- And simple test---
Try following steps:
1. Run terminal windows
2. Get root privilleges (su)
3. In terminal execute next commands:
Code:
mkdir /cdmnt
mount /dev/hdc /cdmnt
Note that /dev/hdb is device IDE0:1 (as set by default)
4. Is there an error ? If no execute ls /cdmnt and check can you see contents of inserted CD.
