Overview

BMSs support secondary virtualization. The user-defined network enables communication between the VM network and the VPC, and provides functions similar to the VPC network for VMs. Application scenarios and benefits include:

  • Private clouds such as XenServer can be provisioned using BMSs.
  • VMs or containers provisioned in the private cloud on BMSs can communicate with the Internet.
  • VMs or containers provisioned in the private cloud on BMSs can communicate with each other.
  • VMs or containers provisioned in the private cloud on BMSs can communicate with ECSs in VPCs.
  • The private cloud system based on BMSs and Direct Connect can communicate with the private cloud in the on-premise data center.

Notes

  • If you have multiple VPCs, you can only create user-defined networks in one VPC.
  • If each of your BMSs has only one NIC, you cannot create user-defined networks.
  • You must create a BMS with a user-defined VLAN before creating a user-defined network.
  • Security groups cannot be configured for user-defined subnets.
