Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)

Reporter: Suresh Kumar Anaparti

Fix For: 4.10
A limit of 13 disks is set in hypervisor_capabilities for VMware hypervisor.
Changed this limit to a higher value in the DB directly for the VMware and
tried attaching more than 14 disks. This was failing with the below exception:
