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: {}
