Each network interface you add to your VM instance is extra PCI(e) card. Each USB controller and/or other PCI(e) device. If you use Q35 on x86(-64) or you use AArch64 then you use PCI Express instead of plain PCI. Then it gets a bit more complicated but still manageable. I have a two blog posts [2] [3] about it from time I worked on getting it working on AArch64 architecture. 2. https://marcin.juszkiewicz.com.pl/2018/02/01/everyone-loves-90s-pc-hardware/ 3. https://marcin.juszkiewicz.com.pl/2018/02/19/hotplug-in-vm-easy-to-say/
