[ovirt-users] Import of OVA fails in 4.0.4

[Derek Atkins]

Hi again,

After a bit more research I found this message in libguestfs[0] that seems
to imply the issue is related to Fedora 23 in that dracut was moved from
/sbin to /usr/bin.  Apparently this was fixed in libguestfs on January 28,
2016 by a change to convert_linux.ml [1].  But apparently this change
isn't in the centos-7.2/ovirt-4.0.4 packages?

I just looked through my ovirt host and canot find "convert_linux.ml"
anywhere, so I have no idea how to actually apply this patch locally.

Short term I suppose I can fix this by adding a symlink in the VM and
repackage the OVA, but it would be nice to actually get this bugfix
propagated; it's been almost a year?

Thanks,

-derek
