The 82579LM chipset supports promiscuous mode so there's no reason it shouldn't support sniffing on arbitrary data as long as your driver supports it. You're only passively viewing frames, whereas ARP spoofing is an active technique. The virtual machine's network interface is a pretend Ethernet interface, which could run in promiscuous mode, but 1) not monitor mode, as it's not a pretend Wi-Fi network adapter and 2) promiscuous mode will capture only on the "network" it's on, which is a virtual network passing traffic between the host and the guest, so, at most, it might be.
