I've got a 3-node Hyper-V cluster running on Server 2025 Datacenter.
One of the VMs is OpnSense.
Whenever I try migrating the OpnSense server to another host, it loses connection.
I've verified the vswitches are identical between the hosts as well as identical physical switch settings.
It is the only VM that is causing me trouble as of now.
I've also tried rebooting OpnSense, disabling and re-enabling the NICa on the host and also shut and no shutting the ports on the switch.
The only thing left to do for diagnostics is to look at the config through the CLI and verify that it is seeing the same NICs as on the original host, but when it boots, it doesn't say anything about not finding the NICs.
Oh yeah, MAC spoofing is also enabled for the OpnSense VM as was recommended as a possible solution via the interwebs.
