Description of problem:

Cold remote migrate VM1 with shared disk(C,F) with migrateSharedDisks:true successfully,
cold remote migrate VM2 with 1 shared disk C - it use the VM1 C, migration failed with error:
"virt-v2v-in-place: error: this guest has no non-removable disks"

cold remote migrate VM3 with 1 shared disk C - it use the VM1 C and 1 no sharing data disk E,
migration failed with error:
"virt-v2v-in-place: error: inspection could not detect the source guest (or phsical 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"

Need to forbidden the migration if not support, or skip the guest conversion

Version-Release number of selected component (if applicable):

2.7.11

How reproducible:

Always

Steps to Reproduce:

1) Prepare a VM: mtv-func-win2022-st2 with 3 disks, shutoff the VM

C 16G st2.vmdk   - shared
E 2G  st2_1.vmdk - no sharing
F 3G  st2_2.vmkd - shared

2) Create cold migration plan: mtv-shared-st2-remote with migrateSharedDisks: true,
    the plan executed successfully

3) Prepare a VM: mtv-func-win2022-st4 with 1 disks, it use the mtv-func-win2022-st2 shared disk C

4) Create remote cold migration plan: mtv-shared-st4-remote-false, the plan failed with "virt-v2v-in-place: error: this guest has no non-removable disks", more details in attached file: mtv-shared-st4-remote-false-vm-125-hnxtf-virt-v2v.log

5) Edit the VM: mtv-func-win2022-st4 to include 2 disks (C - mtv-func-win2022-st2 shared disk C, E - no sharing data disk )

6) Create remote cold migration plan: mtv-shared-st4-remote-false-2disks, the plan failed with

error: "virt-v2v-in-place: error: inspection could not detect the source guest (or phsical 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"

Actual results:

In step 4,6: migrate plan failed

Expected results:

In step 4,6: migration plan executed successfully or forbidden the migration
