This is how it's described in bhyve(8). Basically you need to configure one for each bhyve VM. Otherwise the VM won't boot. I'm not sure if there's an equivalent device in other Hypervisors. I've used KVM for quite some time and didn't need to configure anything similar
lpc LPC PCI-ISA bridge with COM1 and COM2 16550 serial ports and a boot ROM. The LPC bridge emulation can only be configured on bus 0.
Ok, so we have the same thing in QEMU, but it is a built-in part of the machine type which we can't move between different PCI slots, so we have never had to represent it in the XML. I think conceptually we'd probably map this to a new controller type eg <controller type="isa-bridge" index="0"> <address type="pci" domain="0" bus="0" slot="NNN" function="0"/> </controller> So you'd just need to define the new "isa-bridge" controller type for the parser and have the bhyve driver honour the <address>, if provided.
