When a VM with NIC attached to a DVS portgroup is backed up, in the restore process, grid shows no default network portgroup instead of the original DVS portgroup.
This problem does not happen for Virtual Switch portgroups.

WORKAROUND
VM can be restored to an available network and then the network assignment can be changed manually in vSphere.
STATUS
Enhancement request number 17510 has been submitted to Development for consideration in a future release of vRanger
