Comment 6 Laura Bailey 2011-04-19 06:48:40 UTC 
If the /etc/fstab of a guest machine contained a reference to a CD-ROM drive (/dev/hdc), both virt-inspector and virt-v2v printed the following harmless warning during inspection or conversion:
   unknown filesystem /dev/hdc
This warning has been suppressed to avoid confusion, and should no longer appear even if the guest machine refers to CD-ROM drives in /etc/fstab.

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
