Satoshi, You are correct about the code that estimates the load time for imaging reservations in VCL 2.2. We have largely changed how VM disk files are managed since then. I don't remember at the moment if those changes were included in 2.2.1 or not. They will definitely be in 2.3. Now, normal reservations and imaging reservations are handled pretty much the same way for VMs. There is still a missing part about knowing if the image files need to be transferred from the image repository to the VM datastore. However, the information needed to compute that is not in the database before a reservation is made. So, unless we add which images are stored in which datastores to the database, that cannot be included in the initial estimated load time.
However, we do have plans to completely rework how the detailed loading information is done so that it is much more accurate and flexible. After we do that, any information about image file transfers will at least be included in the detailed loading information and will be reflected in the estimated time remaining on the Current Reservations page. I'm not sure if this will be included in 2.3 or not. I'd guess more toward it not being included so we can just try to get 2.3 out as soon as possible.
