Installing an OS on an iMetal Server

After an iMetal server is imported and installed, no OS is installed. You need to install an OS for the iMetal server on the management console.

OS installation includes selecting an image for the iMetal server, configuring a network, and setting the remote login password.

After the OS is installed, Management Status of the iMetal server changes to Running. You can remotely log in to the iMetal server.

Currently, only Linux private images can be installed on an iMetal server.
During the installation of an OS on an iMetal server, other operations on the server cannot be performed.

An iMetal server has been imported, and Management Status of the iMetal server is Ready.

Log in to the CloudDC console.
In the navigation pane, choose Servers > iMetal Servers.
The iMetal Servers page is displayed.
In the iMetal server list, select the iMetal server where an OS is to be installed.
Click Install OS above the list.
The Install OS page is displayed.

Configure parameters as follows.

**Table 1** Parameters for installing an OS
Parameter		Description
OS	Image	Currently, only private images are supported. A private image is a personal image created or imported by a user and is visible only to the user who created or imported it. A private image contains an OS, preinstalled public applications, and a user's private applications. For details, see Creating a Private Image for iMetal Servers.
Network	VPC	With CloudDCN subnets, you can connect iMetal servers to an isolated, private, and high-performance cloud network. You can select an available VPC from the drop-down list or create a VPC as required. For details, see Creating a VPC and Subnet and Creating a CloudDCN Subnet.
Network	CloudDCN Subnet	After a VPC is selected, the system does not associate the CloudDCN subnet by default. You need to select a CloudDCN subnet and set the private IP address assignment mode. If no CloudDCN subnet is available, see Creating a CloudDCN Subnet.
Login	Login Credentials	Login credentials are used to set the mode for logging in to an iMetal server. Password: The initial password is used to log in to an iMetal server. You can log in to the iMetal server using the username and password.
