Hello, friend!

1. Log in to the FusionSphere OpenStack controller node.

Use PuTTY to log in to a controller node in the FusionSphere OpenStack system using the IP address corresponding to the Cascading-Reverse-Proxy field.

The default username is fsp.

2. Switch to the root user.

su - root

3. Run the following command to disable user logout upon system timeout:

TMOUT=0

4. Import environment variables. For details, see Importing Environment Variables.

5. Run # nova list --all-t | grep "SHUTOFF" | cut -d" " -f2 | xargs -t -L1 nova start.

Note:

You are advised to contact Huawei engineers to operate it.

Hope this helps!

Hello, friend!

Before the VM fails to start, check whether any operations have been performed on the hypervisor or whether any exceptions have occurred.

Wait for your feedback!

Hello, friend!

You can try the following commend:

# nova list --all-t | grep "SHUTOFF" | cut -d" " -f2 | xargs -t -L1 nova start

The nova list --all-t | grep "ACTIVE" | cut -d" " -f2 | xargs -t -L1 nova stop command is a high-risk operation. You are advised to contact the TAC for preventive maintenance. Prevent service faults.

Hope this helps!
