When user makes a selection for image. The web front end only checks
the for the currentimageid set in the database. If it user's selection
matches the current image recorded in the db, then est wait time is less
than a minute.
When the user makes the selection, the processing begins. The est value
can change depending on whats really loaded or not. If it doesn't match
and the node needs to be loaded then the est value changes accordingly.
Basically the web scheduling app depends on the information in the
database to be correct, since it doesn't normally have access to the
private network to directly confirm what's loaded. It's up to the
backend (vcld) management nodes to make sure it's correct after a node

Can someone give me a quick overview on how VCL obtains the mins until the
reservation is available? I am having issues where VCL estimates 1 min even
when it is provisioning a VM from scratch. I typically have my image Estimated
Reload Time set to 10 mins since it takes us about 6-8 mins to fully build and
prepare an image.
