Steps to Reproduce:
1.Prepare a windows guest on VMware

2.Convert C drive from basic to dynamic in disk management, pls refer to attached screenshot

3.Convert the guest from VMware by v2v

1. virt-v2v -ic vpx://root@10.73.213.107/data/10.73.212.38/?no_verify=1 -it vddk -io vddk-libdir=/home/vddk7.0.3 -io vddk-thumbprint=87:F9:29:E7:33:DE:34:68:74:3F:6A:C9:61:96:C3:51:E2:1E:EA:2B -ip /home/passwd esx7.0-win10-x86_64-LDM
   [ 1.3] Setting up the source: -i libvirt -ic vpx://root@10.73.213.107/data/10.73.212.38/?no_verify=1 -it vddk esx7.0-win10-x86_64-LDM
   [ 3.3] Opening the source
   [ 13.5] Inspecting the source
   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.

If reporting bugs, run virt-v2v with debugging enabled and include the
complete output:

virt-v2v -v -x [...]

Actual results:
As above description

Expected results:
virt-v2v can convert windows guest if C drive is dynamic
