Description Adam Litke 2014-10-20 20:16:54 UTC 
Description of problem:

Libvirt will be gaining the ability to report allocation information for internal volumes in the live domain XML.  Vdsm uses this information during an active live merge operation to determine if any sparse internal block volumes need to be extended.  The current code assumes that the information will always be provided but the libvirt community decided to provide the information only when the VIR_DOMAIN_XML_BLOCK_INFO flag is passed to virDomainGetXMLDesc().  Therefore, we need to add logic to pass this flag when we require the information.

Version-Release number of selected component (if applicable):
oVirt-3.5

How reproducible: Not yet reproducible since the code has not been delivered into upstream libvirt yet.
