Description of problem:

Create a VM: mtv-func-suse15sp6-en with btrfs lvm, disk with encryption, try to warm migrate it to OCP cluster, migration failed in PreflightInspection phase, the root cause is the plan without luks key, it's better if we update the error message to show this failures in plan or in conversion pod log.

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

MTV 2.10.1-2 with CNV 4.20.2

How reproducible:

Always

Steps to Reproduce:

1) Create a vCenter provider with certificate validation: v7-us

2) Create a VM: mtv-func-suse15sp6-en with btrfs lvm, disk with encryption, 2 interfaces: 1 VM network: dhcp,  1 Mgmt network: static ip, with '/dev/sdb1' mounted to /sdb in /etc/fstab.

3) Create warm migration plan to migrate VM: mtv-func-suse15sp6-en from vCenter to OCP cluster, the plan failed in PreflightInspection phase. Please see more details in attached inspection pod log: warm-suse15sp6-en-vm-4040-inspection-czsfg-virt-v2v-inspection.log

4) The Plan yaml file, Migration yaml file, controller pod log are attached.

Actual results:

In Step3: The migration failed in "PreflightInspection" phase

Expected results:

In Step3: The migration executed successfully

Additional info:

Warm migrate VM: mtv-func-suse15sp6(disk without encryption, second disk is mounted on /sdb in /etc/fstab with UUID) from vCenter7 (with certificate validation) to OCP 4.18.28 cluster successfully.
