How to adjust the VM memory reservation ratio

Hello, dear!

Have a nice day!

1. Region Type I scenario (cascaded scenario):

Use PuTTY to log in to the controller node in the cascaded FusionSphere OpenStack system using the Cascaded-ExternalOM-Reverse-Proxy IP address.

The default username is fsp, and the default password is Huawei@CLOUD8.

Region Type II or Region Type III scenario (non-cascading scenario):

Use PuTTY to log in to the controller node in the FusionSphere OpenStack system using the ExternalOM-Reverse-Proxy IP address.

The default username is fsp, and the default password is Huawei@CLOUD8.

2. Run the following command and enter the password Huawei@CLOUD8! of user root to switch to user root:

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 the following commands to change the memory reservation rate of the host in the host group:

cps template-params-update --service nova nova-compute --parameter ram_reservation_ratio=0.2 --cluster group1

cps commit

6. Run the following command to check whether the setting above has taken effect.

cps template-params-show --service nova nova-compute --cluster group1 | grep ram_reservation_ratio

Check whether the value of ram_reservation_ratio in the command output is the configured value.

Hope can help you!
