Description Arik 2014-04-29 10:58:39 UTC 
Description of problem:
Memory volumes should be taken into account as part of the "Snapshot Overview" feature [1], as snapshots now contains memory dump by-default which might produce very big volumes on the storage, so the users should be aware of that.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.
2.
3.

Actual results:


Expected results:


Additional info:
Currently the memory volumes are not presented as an entity in ovirt, which makes it more difficult to handle the memory volumes and in particular to expose them in the "Snapshot Overview" dialog.

As a temporary solution we can show the memory by checking whether the snapshot contains memory and calculate its size by the formula that we use in order to determine what the size of the memory-dump volume is expected to be.

Later on, when the memory volumes will be represented as business entity, we could simplify the solution and above, include memory volumes which are used for suspended VMs, and provide more information about those volumes.

As of 4.2 it is possible to see memory volumes in the storage domains and also manage them (move and delete from storage)
