What is the equivalent operation in oVirt for a disk?
How does the concept of Image, Snapshot and Volume of OpenStack relate
to disks in oVirt?
Please suggest.
Thank You,

a disk == volume
an image is more like a template in ovirt.
you can instantiate multiple VMs, thinly or cloned" from a template.
one difference is that a template has both the "image" (via the disks in
it), as well as the default VM config, while in openstack an image
doesn't have a config associated with it, as the config comes from the
flavors. in 3.5, ovirt adds ability to use instance types (flavors) on
top of the template mechanism (and for plan VMs as well).
you can 'create snapshot' on a VM (for all its disks), or since 3.4, on
a specific disk.
