After Linux VMs using PV drivers are started in batches, their IP addresses cannot be queried occassionally. Running the ifconfig command on the VM shows that the IP addresses are not on the NIC.
The VM startup log shows that the NIC is not started during the network service startup
If it is certain that the field ifcfg-eth* is renamed ifcfg-eth*.bak during the VM shutdown or startup, run the following command on the VM to check whether the kudzu service is running.
ps -ef|grep kudzu
If the service is running, run the following command to stop the service:
chkconfig kudzu off
Then, rename ifcfg-eth*.bak ifcfg-eth*, and restart the network service or VM.
If this problem is not caused by this field, contact Huawei technical support.
The field ifcfg-eth* is renamed ifcfg-eth*.bak, which cannot be recognized by some Linux OS. Therefore, the NIC is not started during the network service startup, causing the IP address not be obtained in DHCP mode.
