BMSs support secondary virtualization. The user-defined network enables VMs provisioned on BMSs to communicate with cloud services in the same VPC, or to communicate with the Internet.
For details about how to use the user-defined network, see the best practice at XenServer on BMS.
The BMS console is displayed.
The user-defined subnet mask is 16 to 29 bits, and the gateway IP address of the user-defined subnet cannot be used.
After the user-defined network is created, you can view its information in the list of user-defined networks.
If you have not created a multi-NIC BMS, message "Insufficient multi-NIC BMSs." is displayed and the user-defined network fails to be created.
You can view the name, AZ, number of user-defined subnets, and VPC information of the user-defined network.
You can also change the name of the user-defined network by clicking next to its name, entering a new name, and then clicking .
Currently, a user-defined network can have only one user-defined subnet. You cannot add user-defined subnets on the details page of the user-defined network.
In the list of user-defined subnets, click the name of the target user-defined subnet to go to its details page.
On the details page, you can view the IP address, status, and tenant VLAN of the user-defined subnet.
On the IP Address page, you can view the IP address of the user-defined subnet and the EIP bound to the subnet.
On the BMS page, you can view information about all the BMSs with multiple NICs.
You cannot directly modify a user-defined subnet. You must delete the user-defined network and then create a new user-defined network and a user-defined subnet again.
In the list of user-defined subnets, locate the target user-defined subnet and click Delete in the Operation column.
If a user-defined network has only one subnet, you are not allowed to delete the subnet.
After the last multi-NIC BMS using a user-defined network is deleted, the user-defined network will be automatically deleted.
