Hmm, try:
pvscan /dev/vdc
Use fdisk to see if partitions can be read. Also, when you copied the data
with dd, did you use the oflag=fsync option? If not, your data could be

When you say "not visible in oVirt" you mean that you do not see them in
the UI? Do you know the specific uuids for the missing volumes? You could
use lvm to check if the LVs are visible to the host.
