-This is the old method for uploading to Glance.  Unfortunately Glance

-
-Note this is a legacy option.  In most cases you should use
-L</OUTPUT TO OPENSTACK> instead.
-
-To output to OpenStack Glance, use the I<-o glance> option.
-
-This runs the L<glance(1)> CLI program which must be installed on the
-virt-v2v conversion host.  For authentication to work, you will need
-to set C<OS_*> environment variables.
-
-Normally there is a file called C<overcloudrc> or C<keystonerc_admin>
-which you can simply C<source> to set everything up.
-
-Virt-v2v adds metadata for the guest to Glance, describing such things
-as the guest operating system and what drivers it requires.  The
-command C<glance image-show> will display the metadata as "Property"
-fields such as C<os_type> and C<hw_disk_bus>.
-
-=head2 Glance and sparseness
-
-Glance image upload doesn't appear to correctly handle sparseness.
-For this reason, using qcow2 will be faster and use less space on the
-Glance server.  Use the virt-v2v S<I<-of qcow2>> option.
-
-=head2 Glance and multiple disks
-
-If the guest has a single disk, then the name of the disk in Glance
-will be the name of the guest.  You can control this using the I<-on>
-option.
-
-Glance doesn't have a concept of associating multiple disks with a
-single guest, and Nova doesn't allow you to boot a guest from multiple
-Glance disks either.  If the guest has multiple disks, then the first
-(assumed to be the system disk) will have the name of the guest, and
-the second and subsequent data disks will be called
-C<I<guestname>-disk2>, C<I<guestname>-disk3> etc.  It may be best to
-leave the system disk in Glance, and import the data disks to Cinder.
