Missing Virtual Network adpter on Node1 from registry

Dear Partner,

I have two servers 2008 R2 failover cluster Node1 and Node2 , We are missing Virtual Network adapter on Node1 (disappear)

Now I check in with below

Switch from registry path : HKLM\SYSTEM\CurrentControlSet\Services\VMSMP\Parameters\SwitchList  (registered ) 
Network adapter from registry path: HKLM \SYSTEM\ControlSet001\Enum\ROOT\VMS_VSMP\     (not registered)

I want to added all missing network Network adapter from registry like below Screen shot

in node 2 because the failover cluster not working when shutdown Node1 the VMs not live migration to Node2

How resolve this issue.

Regards,

Magdy
