Hi Sandy,
virtual size is the size of the disk the VM knows, it is actually the size you chose to create it with. The true size is the summerise of all the true size which the volumes related to disk.
So for example if you have one disk of 20G and you occupied 18GB of it. Then you created a snapshot and you occupied 4GB of it, you might see that the virtual size will still be 20GB though the true size will be 22 GB
You can also check in the host the commands: vdsClient 0 getVmStats <vmId> or vdsClient 0 getAllVmStats.
why at host level and not via api or ovirt-cli?
That is correct, you can also see the size and the fields through the API or ovirt-cli (see http://documentation-devel.engineering.redhat.com/site/documentation/en-US/R...) though, you can not see the true size in the floating disk, IINM you can see it under the VM snapshots disks in the API. I think that since I already saw this question before, maybe its worth to open an RFE on that issueת perhaps changing the column name to full_disk_size ןמ איק GUI or adding a column of actual size in the disks main tab?
Regards, Maor

Assign 20G virtio disk for VM, create an offline snapshot, find the true size of Vm-disk bigger than the virtual size (assign size)?
I want to know how to compute the true size of vm-disk. Anbody can tell me the answer ? thanks.
