PVS Tab:
- Move the "View PVS sites" button inside the "Configure PVS Cache" dialog (next to Remove button) and make it per-site (showing only the PVS servers from that site)
- Remove "Currently attached" column from the VMs section
- Rename "Status" column to "Read caching status"
Configure PVS Cache" dialog:
- Make sure there is a scrollbar to accommodate all hosts in a pool
- Add a confirmation dialog when a site is removed. The action is executed when the Remove button is pressed.
- When Memory SR is selected, set the maximum value to the dom0-extra-memory..
- Allow empty configuration (but see next point): The OK button should only be disabled if the PVS site name is empty
- Add an extra option in the "Cache storage" combobox, with text "Not configured", selected by default on a new site. When this is selected, we will remove the existing entry in pvs_cache_storage and will not create a new one.
- When a PVS site is deleted (forgotten), we first delete all the associated PVS_servers, otherwise the site cannot be deleted.
