/etc/qemu-ifup脚本在启动虚拟机的网络接口时运行,用于配置虚拟机的IP地址、子网掩码、网关等
sudo vim /etc/qemu-ifup
#添加如下内容
#!/bin/sh
switch=br0
interface=ens33
if [ -n "$1" ]; then
switch_exit=`sudo ifconfig -a | grep $switch`
interface_switch=`sudo brctl show | grep $interface`

sudo brctl addbr $switch

if [ "$interface_switch" = "" ] ; then
sudo ifconfig $interface 0.0.0.0 promisc up
sudo brctl addif $switch $interface

sudo ifconfig $1 0.0.0.0 promisc up
sudo brctl addif $switch $1
sudo dhclient $switch
else
echo "Error: no interface specified"
exit

/etc/qemu-ifdown脚本在关闭虚拟机的网络接口时运行,用于清除虚拟机的网络配置
sudo vim /etc/qemu-ifdown
#添加如下内容
#! /bin/sh
switch=br0
if [ -n "$1" ]; then
# sudo tunctl -d $1
sudo brctl delif $switch $1
sudo ifconfig $1 down
else
echo "error: no interface specified"
exit 1

在Linux中创建一个桥接接口br0,并将物理接口eth0添加到该桥接接口上。这样虚拟机可以通过eth0与宿主机进行网络通信。配置好后重启系统sudo reboot
sudo chmod +x /etc/qemu-*
sudo apt-get install uml-utilities bridge-utils
sudo vim /etc/network/interfaces
#添加如下内容
auto eth0
iface eth0 inet manual
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_fd 0
#创建一个名为br0的桥接接口,并使用DHCP协议自动分配IP地址
#bridge_ports eth0表示将物理接口eth0添加到桥接接口br0上
#bridge_stp off表示关闭STP(Spanning Tree Protocol)
#bridge_fd 0表示禁用桥接接口的转发延迟

windows启动tftp服务器,将编译好的cli放在设置好的共享目录
#arm64虚拟机通过tftp获取cli文件
tftp -gr cli 192.168.11.29
chmod +x cli

#ubnutu18.04运行ser
./ser
#arm64虚拟机运行cli
./cli

运行下面命令,创建配置文件 /etc/modprobe.d/blacklist-vmware.conf。然后重启sudo reboot
sudo tee /etc/modprobe.d/blacklist-vmware.conf << EOF
blacklist vmw_vsock_virtio_transport_common
blacklist vmw_vsock_vmci_transport
EOF
这是由于linux 检测到在 vmware 环境中运行时,会加载一些 vmware 的模块并使用 vsock 从而产生了冲突。
可以通过命令lsmod | grep vsock来查看哪些模块产生了冲突。
命令输出:
core@ubuntu20-dev:~$ lsmod | grep vsock
vmw_vsock_virtio_transport_common 32768 0
vmw_vsock_vmci_transport 32768 1
vsock 36864 3 vmw_vsock_virtio_transport_common,vmw_vsock_vmci_transport
