OK, it's a bit different, my apologies.

Please post the full output with ‘virt-v2v -v -x’ options both
enabled.  We use this debugging information to see how inspection and
v2v are working.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.

It’s the same input OVA, but using the latest libguestfs release.

Updated log attached (sorry; thought I had the necessary flags enabled).

Thanks,
Zach

CC-ing to Pino because I think this is an augeas / overriding
augeas lenses problem.

libguestfs lets you edit virtual machines.  Supports shell scripting,
bindings from many languages.  http://libguestfs.org

The error message is:

  installed kernel packages in this guest:
  virt-v2v: error: no installed kernel packages were found.

This is because no kernel packages are found in the guest, and indeed
I can see in the log:

  libguestfs: trace: v2v: inspect_list_applications2
"/dev/vg0/lv-root"
  libguestfs: trace: v2v: inspect_list_applications2 = <struct
guestfs_application2_list(0)>

Since it's a own build, most probably libdb-utils was not installed
when configure was run, and thus libguestfs did not download and
inspect the content of the RPM DB in the guest.

See also http://libguestfs.org/guestfs-building.1.html for the list of
mandatory, and optional build & runtime dependencies.
