Description of problem:
Disk actuall size is twice than the virtual (and real) size.
Version-Release number of selected component (if applicable):
Steps to Reproduce: On a block pool with 1 host and 2 storage domains:
1. Create a vm with 2 disks (50g each)
2. Check actual size of both disks is 50g
3. Create a snapshot
4. Check actual size of both disks is 100g
5. Also try to move (migrate) one of the disks to a storage domain with ~90g free, and see that it fails due to not enogh space.
The actuall disk size shows 100g.
The actuall disk size will show the currect value (50g).
virtual size indicates the size that the OS using when read/write the disk (should be 50GB).
actual size should indicates the size that the disk occupies in the storage including its snapshots, since the disk is preallocated (as I saw in the logs) and it had a snapshot, its actual size should be 100GB
Based on comment 1, closing as not a bug.
