PowerFlex: Power on VM fails error A general system error occurred: vDS host error

Powering on a virtual machine (VM) fails with the error:

A general system error occurred: vDS host error

Or 

A general system error occurred: vDS host error: see faultCause Cannot create DVPort ### of VDS <DISTRIBUTED SWITCH NAME> on the host <hostname.example.com>

Environment

1. Find the VM object in the vCenter Hosts and Clusters view.
2. Right-click the VM and select Edit Settings
3. Make note of all the virtual NIC settings.
4. Delete the virtual NIC. If the VM has more than one virtual NIC, only remove one virtual NIC at a time. If you are using vCloud Director, see Remove a Network Interface (External Link)

5. Save the change.
6. Right-click the VM again and select Edit Settings
7. Readd the virtual NIC using the same settings.

If the VM has more than one virtual NIC, and still does not power on, use steps 1-7 for the next virtual NIC.

Prior to following the steps for removing NIC and adding back, the issue may be resolved by also changing the port group on the VM, powering it on and then change it back to the original.

Ensure you write down the original port group assigned to the VM, and change it back to this once the VM is up and running again. 

Impact or Risks:
Removing then readding VM virtual NICs should NOT be done when using VMware add-on products such as:

• vRealize Automation
• Horizon View
• vCloud Director
• VMware Integrated OpenStack
