[Fault type]: The VM fails to be started, and a message is displayed indicating that the VM fails to be mounted to the disk.

[Cause Analysis]:

1、    According to the preceding task execution failure message, it is suspected that the VRM fails to connect to the CNA.

2、    The ping CNA in the VRM is reachable, indicating that the IP layer is reachable.

3、    According to the analysis of logs, it is found that the communication between the VRM and CNA is denied. Therefore, the nc process on the CNA may be abnormal.

4、    Log in to the CNA using SSH to confirm that the nc process is rejected. Use the BMC IP address to log in to the server using the KVM. It is found that the nc process is normal. Therefore, it is suspected that the IP address conflicts with the IP address and the CNA management network adapter is down, if the IP address can be pinged, the IP address already exists. After the check, it is found that a Windows physical machine has the same IP address.
