-Glance image upload doesn't appear to correctly handle sparseness.
|
|
|
-For this reason, using qcow2 will be faster and use less space on the

|

-If the guest has a single disk, then the name of the disk in Glance

|
|
|
-
|
|
|
-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.
