Hi Alex,

There are two ways to create a VM, either on Compute Internal Disk(ephemeral disk) and Cinder Block Storage Volume. When we go with first option then disk size is picked from flavor that we specify during VM provisioning.

When we provision a vm using Block storage Volume ( i.e Cinder Volume) then we specify disk size while creating Bootable volume, refer below command to create bootable volume using glance image,

# cinder create –image-id {enter-image-id} –display-name bootable-volume 15

In the above command, 15 GB is size of volume.
