In the past, using qemu-kvm to run virtual machines is basically a nat method. virtual machines can access external networks and basically meet their own requirements, but they cannot access the virtual machines. Now, because we need to deploy the environment on the Virtual Machine for Virtual Network Management of openstack, we need the correct access between virtual machines and the ip address for external access.Environment Configuration Hardware: cpu dual-core, four threads, 8 GB memory OS:

1. This Nic uses the chip set of atheros Communications Inc. ar2413 and can use the madwifi Driver (www.madwifi-project.org ). The Linux kernel now has the madwifi driver named ath5k by default. However, this driver is faulty when the NIC is configured as AP. Therefore, we need to replace it with the ath_pci driver, which is also the driver in the madwifi project. 2. So, first Pacman-s madwifi-utils wireless_tools, then morprobe-r ath5k and ban ath5k
