how to enable promiscuous mode wireshark

Sorry, edited my post as I didn't read your properly and realized you've actually already done what I had thought might be the next step. As far as I know if NIC is in promisc mode it should send ICMP Reply. This is one of the methods of detection sniffing in local network.

This is a huge setback for me as I completely rebuilt/upgraded this box to take over running my 24/7 VMs I had hosted on ESXi to reduce power consumption. I've checked options 'Capture packets in promiscuous mode' on laptop and then I send from PC modified ICMP Request (to correct IP but incorrect MAC address). The only way around this that I can think of might be to try passing through an entire dedicated capture NIC to the VM but I'd rather not have to do this because I wanted to have multiple IDS/packet-capture VMs running, all capturing from a single physical interface. Everything below is just for history in case it helps other people. Update 1 - I also solved the issue by passing through a PCIe slot as well as 'half' a 4-port NIC. Update 2 - I have now also come up with a way to do all this without using an entire NIC passed through to each VM.
