Question about HA and IoT VLAN

I have a VMWare setup for HA and the host machine and VM are on my main LAN. I also have an IoT vlan setup where all my IoT devices are connected. My main lan can connect to the vlan but not the other way around.

Everything seems to be working fine, but was wondering if I should be moving the VM and host into the vlan or not. Is there any reason/advantage? The only thing is I see some devices trying to connect back to the VM HA machine. Thanks.
