After updating Veeam or VMware such that a combination of ESXi 5.5 and Veeam 7.0.0.764 or higher exist within the environment, the jobs fail with error “Failed to open VMDK” and/or “Host not licensed for this feature.” The job will successfully download the VMX, VMXF, and NVRAM, but will fail on the VMDK.
In Veeam Backup & Replication v8 this issue appears with the error “Failed to create processing task for VM <vmname> Error: Cannot access VMX file of VM ‘<vmname>’” and “Task failed Error: Cannot access VMX file of VM ‘<vmname>’”
