                Solving an issue with VirtualBMC running in macOS
              
          
    How to fix VirtualBMC in macOS

After installing VirtualBMC in macOS, starting the server and adding a BMC for at least one VM, and then trying to start that BMC, you get the following error:
INFO VirtualBMC [-] Started vBMC server on port 50891
ERROR VirtualBMC [-] Control server error: Can't pickle local object 'VirtualBMCManager._sync_vbmc_states..vbmc_runner'

This is because the multiprocessing module needs to specify fork as the startup method, since starting with Python 3.8 for macOS the startup method has been replaced by spawn.

                L2 NAT for a VLAN interface with a wireless parent interface bridged to the VMs in macOS
              
          
    IEEE: 802.11 (Wi-Fi), 802.1Q (VLAN tagging); bridges and VMs in macOS Sonoma

If for some reason you need to tag traffic outgoing from a vNICs of VMs bridged to a wireless interface in macOS, you can do so as follows.
I will describe this process with VLAN configuration on an OpenWrt router with DSA support.
Configuring the router:

Open the interfaces tab on the Network menu in LuCI. Switch to the Devices tab and click configure br-lan, then switch to Bridge VLAN filtering and configure as in the screenshot below.
