If you use an DHCP server it might give the same IP address to both devices. This line cannot be correct: sudo qemu-system-x86_64 -enable-kvm -m 8G -smp 4 -hda ubuntu18.qcow2 -boot d -cpu host -netdev tap,id=foo,ifname=tap0 -device virtio-net-pci,netdev=foo0 as the id and netdev do no have the same name. You might try with: sudo qemu-system-x86_64 -enable-kvm -m 8G -smp 4 -hda ubuntu18.qcow2 -boot d -cpu host -netdev tap,id=foo0,ifname=tap0 -device virtio-net-pci, mac=52:54:00:12:34:56 ,netdev=foo0 and sudo qemu-system-x86_64 -enable-kvm -m 4G -smp 2 -hda ubuntu22.qcow2 -boot d -cpu host -netdev tap,id=foo1,ifname=tap1 -device virtio-net-pci, mac=52:54:00:12:34:66,netdev=foo1
