Virtual machine creation failure cause quick troub (Published on:3/11/2018 12:52:23 PM)

Incident Description (Incident Phenomena)
Virtual machine creation failed, creating a direct error
 Networking Environment
Standard VCN networking or VEON standard networking.
 Problem Cause Analysis
The cause of the failure to create a virtual machine General tecs interface will be prompted for a reason, but the hint is relatively simple and may not be the correct solution to the problem. Need to check the relevant log to find the specific reasons.
 Solution

1, login control node, nova show uuid

2, if the host value is null, continue to collect the following information in the main control node,

The host value is not empty, you need ssh to the computing node to collect the following information

3, this is already a node information, you need to log in to the computing node query var / log / nova / nova-computer.log log,

cat var / log / nova / nova-computer.log | grep uuid.

4, the query results are as follows:
Image 73a56d4c-3418-46fa-acf0-ab9fb52fcc60 is unacceptable: Size is 96GB and does not fit in a volume of size 80GB.

5, prompted to create a virtual machine image used 98G cloud hard disk, but only created when the configuration 80G

6, Solve the problem, reset the cloud hard disk is 100G, the virtual machine is created successfully

 Summary and Notes

1, the virtual machine to create the first step failed to see tecs suggested that the general problems can see the reasons

2, if you can not see through the error message, we must follow the steps step by step troubleshooting.
