-

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

-with "pets" not templated "cattle"), so this method is not recommended

-=head1 OUTPUT TO 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.
