Hello,
we are currently encountering the above error during virt-v2v
migration. There was an older post about it here:

The answers suggest that this is already fixed upstream
and that you only need virt-v2v for OS disks. Could someone,
explain
- how to migrate only the OS disk and to dd the data disks.
- if there exist any offical patches to fix the bug.
Unfortunately it isn't fixed upstream. The only current workaround is to
edit GuestfsHandle.pm on the machine running virt-v2v. Change:
$g->add_drive_opts($path,
format => $format,
iface => $interface,
name => $name);
to:
$g->add_drive_opts($path,
format => $format,
name => $name);
and:
# Add the transfer iso if there is one
$g->add_drive_opts($transfer,
format => 'raw', iface => $interface,
readonly => 1)
if defined($transfer);
to:
# Add the transfer iso if there is one
$g->add_drive_opts($transfer,
format => 'raw', readonly => 1)
if defined($transfer);
However, this is known to cause problems when converting guests running
older versions of RHEL (RHEL 3 and possibly 4).
