Weird issue. I am moving a bunch of VM's via vMotion and SVMotion into an entirely new datastore and a new cluster.
The VM's were originally on a distributed Switch. The clusters are on separate distributed switches so I just created standard switches on the host and changed the vLAN on these Vm's to that of the newly created standard switch.
The migration works fine. The weird issue is when I change the VLAN to the new distributed switch and power up the VM. The Guest OS does not see the Network adapter. If I go into "edit settings" of the VM I can see the network adapter. If I remove the network adapter, and add a new network adapter it still does NOT see the network adapter.
This is the fix that I found:
1. Remove the NIC. Uninstall VMware tools. Reboot.
2. Reinstall VMware tools. Reboot.
3. Add the NIC card and it will now show in the Guest OS.
My question is why is this happening? Is there a better method to do this upfront so I do not have to play around rebooting and reinstalling VMware tools?
Thanks,
