It looks to me some issue with Storage reservation policy, as i checked for the KB article where no workaround mentioned. VMware KB: Provisioning a machine in VMware vCloud Automation Center fails with the error: Allocate reservation oper…
I do not have any Storage Reservation policy defined and assigned to any Reservation/Provisioning Group or Blueprint.
surprisingly, i can successfully provision VM from vCAC Portal but not from Self Service Portal.
Please help me with this issue if someone else also encountered .. 
Thanks in Advance
