Other images have the following restrictions:

  • By default, they do not come with any initialization. Therefore, the initialization steps such as password setting, network setting, SSH installation, NTP configuration, Yum source configuration, etc. during the creation/reinstallation of the host will not take effect. Users need to configure it themselves through the console login function. Please refer to the 'Manual Initialization Steps'.
  • The console password modification function cannot take effect.

Manual Initialization Steps:

  • Before uploading, the DHCP must be enabled inside the image to automatically obtain the internal network IP.
  • Upload the image through the console, and create a host through this image.
  • Enter the virtual machine internally through the cloud host login function on the console.
