What Restrictions Are There on BMS Use?

Updated on 2024-08-02 GMT+08:00
  • External hardware devices (such as USB devices, bank USB keys, external hard disks, and dongles) cannot be loaded.
  • Out-of-band management is not supported. Your BMSs are managed and maintained by Huawei Cloud.
  • Live migration is not supported. If a BMS is faulty, your services running on it may be affected. It is good practice to deploy your services in a cluster or in primary/standby mode to ensure high availability.
  • You cannot create a server without an OS, that is, a BMS must have an OS.
  • After a BMS is created, you cannot change its VPC.
  • Virtualization software cannot be installed on a BMS.
  • When you create a BMS, you can only select a flavor with specified CPU, memory, and local disks but cannot configure them separately. After a BMS is created, you can expand the capacity of attached EVS disks but cannot modify the BMS CPU, memory, or local disks.
  • You can only attach EVS disks whose device type is SCSI to a BMS.
  • You cannot attach EVS disks to BMSs of certain flavors or BMSs created from certain images because these BMSs do not have SDI iNICs or lack compatibility.
  • Do not delete or modify built-in plug-ins of an image, such as Cloud-Init and bms-network-config. Otherwise, basic BMS functions may be unavailable.
  • If you choose to assign an IP address automatically when you create a BMS, do not change the private IP address of the BMS after the BMS is provisioned. Otherwise, the IP address may conflict with that of another BMS.
  • BMSs do not support bridge NICs because they will cause network interruptions.
  • Do not upgrade the OS kernel. Otherwise, the hardware driver may become incompatible with the BMS and adversely affect the BMS reliability.
  • You can stop a BMS only on the management console and cannot run shutdown to stop it.
  • Quotas are enforced for service resources on the platform to prevent unforeseen spikes in resource usage. The BMS service has no independent quota. It shares the number of instances, CPU cores, and memory with the ECS service. You can view BMS quota in the Elastic Cloud Server row. For details see How Do I View My Quotas?
