Mike and Maxim, Yes, it is very slow, there are some reasons: The host: For easily adding NICs to be used, I run Ubuntu on virtualbox, that is to say, even my HOST is actually a virtual machine too. It is low efficient but convenient to add NICs and config guest NAT net to not to impact my company's LAN. The guest: I didn't enable some advanced acceleration methods such like kvm and virtio, so the guest is slow too, I can try to enable them gradually.
Santosh is right, this is functional and can be materials for running it in Lava.
