eBlockerVM-2.9.1-amd64.ova / virt-v2v: error: libguestfs error: you must call guestfs_add_drive before guestfs_launch

[minger0]

rwmjones 17c6d52 reported the eBlockerVM-2.9.1-amd64.ova working on the latest after his commit, so I followed the install steps and installed virtv2v latest to /usr/local/bin/virt-v2v, hoping that it would work for me just like for rwmjones. It did not, because I get a
virt-v2v: error: libguestfs error: you must call guestfs_add_drive before
error instead. See details below. Question: how to get the eBlockerVM-2.9.1-amd64.ova conversion working?

which virt-v2v

/usr/local/bin/virt-v2v

/usr/bin/virt-v2v --version

virt-v2v 1.44.2

About eBlockerVM in general: The OVA uses an unusual, newer OVF variant than we currently support, and as a result virt-v2v cannot right now be used to import it.

There is a bug about this: https://bugzilla.redhat.com/show_bug.cgi?id=2183999

Do you expect a solution coming in a few weeks?
If not, is there a temporary one-off bootstrapping for the issues you mentioned?
(1) The xmlns changed to: xmlns="http://schemas.dmtf.org/ovf/envelope/2"
(2) ovf:version="2.0" in the <Envelope>
(3) Uses <StorageItem> instead of <Item>

[rwmjones]

It's a volunteer project and everyone is welcome to contribute. That said, this particular new format is hard to implement and apparently not used by VMware.

It may well be possible to modify the OVF to turn it into a v1 format. You might want to start by looking at some other example OVFs to get the idea, such as the ones we use for testing here: https://github.com/libguestfs/virt-v2v/tree/master/tests
