Hello, friend!

Have a nice day!

You can refer to the following steps:

1. Use PuTTY to log in to the host.

Ensure that the management IP address and username gandalf are used to establish the connection.

The system supports the login authentication using a password or private-public key pair. 

2. Run the following command and enter the password of the root user to switch to the root user:

su - root


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

TMOUT=0


4. Run the following command to obtain the default memory reserved for the host virtualization suite:

CNA3647:/ # python /opt/vna/sbin/domain0_default_memory_spec.py  
Domain0 default reserved memory: 3273MB


In the command output, 3273 MB indicates the default memory reserved for the host virtualization suite.

Hope can help you!
