root@ubuntu-2:~# sudo lshw -class network *-network description: Ethernet interface product: Virtio network device vendor: Red Hat, Inc physical id: 3 bus info: pci@0000:00:03.0 logical name: ens18 version: 00 serial: fa:16:3e:aa:ee:d4 width: 32 bits clock: 33MHz capabilities: msix bus_master cap_list rom ethernet physical configuration: autonegotiation=off broadcast=yes driver=virtio_net driverversion=1.0.0 ip=192.168.56.82 latency=0 link=yes multicast=yes resources: irq:10 ioport:c060(size=32) memory:febd1000-febd1fff memory:feb80000-febbffff root@ubuntu-2:~# |
二、配置网卡，vi /etc/network/interfaces

auto ens18 iface ens18 inet static address 10.10.10.50 netmask 255.255.255.0 gateway 10.10.10.1 |
三、临时配置DNS，重启失效。vi /etc/resolv.conf
