Error creating macvtap interface for vm

[curiouskid]

After great deal of research I learn that e1000 should be device model and USB as disk type to have ESXi as VM in unRaid.

Now, unRaid hosted my ESXi_VM, starts without any issues with following two NICs attached.

 

Bridge br0: Host device bound0 (e1000 as device model)

Bridge docker0: Empty bridge (e1000 as device model)

 

Added Citrix Netscaler VPX on ESXi and setup basic connectivity to front end.

When everything regarding back-end failed, I realized that I have Bridge docker0: Empty bridge as 2nd NIC on my ESXi.

 

Now, I am trying to add eth0 (connected to router/Internet ) and eth1 (Connected LAN) to my host ESXi_VM.

When I tried to add them as following, I got error.

 

Host Device eth0: macvtap

Host Device eth1: macvtap

Could it be result of bonding and bridging configured on unRaid?

Attached screenshot shows what my configuration looks like. (See attachment)

If that needs to be changed, can someone please advice on what options can I select here?
