The error occurs when "virt-v2v" command is executed

Issue

• When a guest OS is migrated from VMware to KVM by using "virt-v2v" command, the following error message is displayed and the migration fails.

# virt-v2v -f /etc/virt-v2v.conf -ic esx://<IP or Host name on VMware>/?no_verify=1 -os guest_images_disk <Guest name>
virt-v2v: Failed to create storage volume: libvirt error code: 27, message: XML error: unknown volume format type raw

• It is ok to add new volumes in pool with disk type, however, it can not handle to add volume with raw format.
• virt-v2v use the raw format with disk type, so the migration fails.
