Centos6 device eth0 does not seem to be present

centos6 网卡启动时报 device eth0 does not seem to be present

• 问题：将centos6 vm 从openstack平台迁移到kubevirt时网络无法启动，报 device eth0 does not seem to be present
• 问题定位：

  ## 查看物理网卡设备
  # lspci |grep -i eth
  01:00.0 Ethernet controller: Red Hat, Inc. Virtio network device (rev 01)
  
  ## 查看逻辑网络设备，发现只有lo
  ls -l /sys/class/net/
  [root@yum ~]# ls -l /sys/class/net/
  total 0
  lrwxrwxrwx 1 root root 0 Jun  7 12:06 lo -> ../../devices/virtual/net/lo
  

• 解决问题，修改interfaces的model为e1000，默认为virtio

            interfaces:
              - name: default
                model: e1000
                bridge: {}
