Issue/Introduction

Symptoms:

Move vmk0 out of this DVS before rename all the uplinks names, or rename the uplink name one by one.
 

Once it occurred, you may need to move vmk0 from DVS to a standard vSwitch.
1. Note the current configuration of DVS.
2. Remove vmnic from DVS.
3. Remove VMkernel port(vmk0) from DVS.
4. Create a new standard vSwitch.
5. Create a VMkernel port and attach it to a portgroup on a Standard vSwitch.
