我对Linux和networking通信相对来说比较陌生，我一直在努力解决以下问题：在虚拟机主机中有一个lxc容器，主机通过接口ens5连接到usrp设备。 我试图build立lxc和虚拟主机之间的桥梁连接，以便lxc也可以访问usrp。 以下是networking的具体细节：
我已经附加ifconfig输出为主机和lxc下面：

使用LXC 2.0，您可以尝试使用macvlan nictypes。 为此，请编辑您正在启动容器的configuration文件。 假设你想编辑默认的configuration文件，然后做
lxc profile edit default
在设备下面，添加另一个nic，如下所示：
devices: eth0: name: eth0 nictype: bridged parent: lxcbr0 type: nic usrp0: name: usrp0 nictype: macvlan parent: ens5 type: nic
然后，在新的容器启动后，添加一个IP地址到新的NIC：
ip address add 172.23.201.78/24 dev usrp0
您现在应该能够从容器ping通usrps。
