A virtual machine cannot retrieve NIC information after being attached to a Distributed Port Group. How do I resolve this?

Cause

QEMU may have dynamically attached the virtual NIC to the virtual machine, but the virtual machine did not recognize it.

Solution

1. Try one of the following methods:

2. Restart the virtual machine. The NIC information is obtained automatically after restart.

3. Run the following commands inside the virtual machine operating system to manually add the NIC configuration file.

   [root@localhost ~]# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1
   # Assuming the existing NIC is named eth0, copy its configuration file as a template
   [root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1
   # Set the following parameters
   TYPE=Ethernet
   BOOTPROTO=dhcp
   NAME=eth1
   DEVICE=eth1
   ONBOOT=yes

4. Run the service network restart command to restart the network.
