Test 802.1Q vlan of nic, config it by vconfig command.
1) Create two VMs
2) Setup guests in different vlan by vconfig and test communication by ping
using hard-coded ip address
3) Setup guests in same vlan and test communication by ping
4) Recover the vlan config
The subnet of vlan can be setup in configure file.
