Unfortunately this is a legacy limitation of virt-v2v which is very hard
to remove. You can try to fix it by manually patching GuestfsHandle.pm
in virt-v2v to remove the 'iface' argument to add_drive_opts.
Specifically, find the following:
$g->add_drive_opts($path,
format => $format,
iface => $interface,
name => $name);
and change it to:
$g->add_drive_opts($path,
format => $format,
name => $name);
and find the following:
$g->add_drive_opts($transfer,
format => 'raw', iface => $interface,
readonly => 1)
if defined($transfer);
and change it to:
$g->add_drive_opts($transfer,
format => 'raw', readonly => 1)
if defined($transfer);
The effects of this change are not well tested, and will definitely
break conversion of older RHEL guests. Guests which natively support
virtio should probably be ok, though.
