Symptoms

Following below method to import VM from Oracle VM Server:
https://blogs.oracle.com/scoter/post/how-to-migrate-oracle-vm-to-oracle-linux-kvm

The virt-v2v returns error as below:
virt-v2v: error: inspection could not detect the source guest (or physical
machine).

Assuming that you are running virt-v2v/virt-p2v on a source which is
supported (and not, for example, a blank disk), then this should not
happen.

No root device found in this operating system image.
