commit e1ddae83901735d9bffd9d736f3c033c8986041f Author: John Hua <[email protected]> Date: Thu Aug 11 14:48:47 2016 +0800 Use physical utilisation for cached images Since glance images are downloaded and snapshotted before they are used. Only a small proportion of its VDI will be in use and it will never grow. So the real disk usage for VDIs varies with their capability to expand. Disks connected to VMs continue to use the virtual utilisation as they are able to expand.

However, this does not have to include glance images. For example: [root@maul ~]# xe vdi-list name-label="Glance Image 792e7f09-0c87-4f60-9861-b580fbc3c9cb" params=virtual-size,physical-utilisation virtual-size ( RO) : 42949672960 physical-utilisation ( RO): 88576 Because the VHD has a virtual size of 40GB when uploaded to glance, the VDI has to be 40GB, but we know it can never increase because we will always take a snapshot of it. This, this 88K of physical utilisation is interpreted as 40GB by our code.
