Logging into Windows Instance via VNC

Last updated: 2019-11-04 14:07:53



VNC login is a browser-based method of CVM remote connection that Tencent Cloud offers its users. When a client does not have remote login installed or cannot use it and in the situation where login cannot be accomplished by any other means, the user can connect to a CVM using VNC login and observe the CVM’s status and can also do basic CVM management operations using the CVM account.

Use Limits

  • The features of copy/paste, Chinese input, and file upload/download are currently not supported on CVMs using VNC login.
  • Main scream browsers must be used when using VNC login of a CVM, such as Chrome, Firefox, and IE 10 or above.
  • A VNC login is a dedicated terminal, meaning that only one user at a time can use a VNC login.
