OVA migration fails with forklift 2.7

[arturshadnik]

Hello!

When migrating an OVA using forklift 2.7, the migration fails during the Disk Transfer stage. The following error is seen in the conversion pod logs:

commandrvf: stdout=n stderr=y flags=0x0

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.

VirtualMachine metadata from conversion pod logs:

metadata:
name: bitnami-wordpress-6-6.2.2-r1-debian-11-amd64
labels:
libguestfs.org/virt-v2v-version: "2.5.6"
libguestfs.org/osinfo: debian11
libguestfs.org/source: vmware

Args used for virt-v2v-inspector
-v -x -if raw -i disk -O /var/tmp/v2v/inspection.xml /var/tmp/v2v/bitnami-wordpress-6-6-2-2-r1-debian-11-amd64-sda

The same OVA can be migrated without issue using forklift 2.6.3. The OVA being migrated is Bitnami Wordpress, from VMWare and using Debian 11 (as shown in the vm metadata) - so it should be supported by virt-v2v.

Happy to provide the full log if needed.
