vCenter接管

介绍

VMware vCenter Server is a centralized management platform of a VMware vCenter.

If you have deployed VMware vCenter Server, you can use ZStack Cloud to manage VMware vCenters by using public APIs provided by VMware. ZStack Cloud is highly compatible with and can manipulate a portion of features of VMware vCenter Server. You can use the vCenter feature to implement a unified management of multiple virtualization platforms.

You can manage VMware virtualization environments in an existing data center, and view vSphere server resources and VM resources managed by VMware vCenter Server. In addition, you can use VMware vSphere resources in a virtual data center, and perform common operations on VM instances in your VMware vCenter cluster.

ZStack Cloud supports multiple vCenter versions, including 5.5, 6.0, 6.5, and 6.7.

基础资源

vCenter的基础资源主要涉及ZStack Cloud对vCenter虚拟化资源的统一管理，目前包括：添加vCenter、同步数据和删除。

首次添加vCenter后，ZStack Cloud会自动同步vCenter的集群、物理机、虚拟机、模板、存储、网络等资源；使用过程中，需要点击同步数据按钮，将vCenter的资源手动同步至本地。相关资源均支持界面查看。
  • 支持添加多个vCenter并进行管理。
  • vCenter资源导入ZStack Cloud支持过滤。
    • dvSwitch scenario:

      Only resources of the hosts added to a dvSwitch can be imported to ZStack. If you do not add a host to a dvSwitch, the associated resources cannot be imported to ZStack.

    • vSwitch scenario:
      Only resources of the hosts in the same cluster, added to at least one same vSwitch, and have at least one same port group attribute (including the same network labels and the same VLAN ID) can be imported to ZStack.
      Note: ZStack can only take over VM networks rather than VMkernels or management networks.

云主机

添加vCenter后，vCenter云主机自动同步至ZStack Cloud；也支持本地创建vCenter云主机。

网络

要在ZStack Cloud接管的vCenter环境中新建云主机，需提前搭建好vCenter中的VPC网络或扁平网络。

vCenter network services currently support the vRouter network architecture model.

A vCenter vRouter network provides network services such as DNS, SNAT, Elastic IP (EIP), port forwarding, load balancing, IPsec tunnel, and Netflow.
  • DNS:
    • A vCenter vRouter can act as a DNS server to provide DNS services.
    • By default, the DNS address that you see in a vCenter VM instance is the IP address of the corresponding vCenter vRouter. The DNS address set by a user is forwarded and configured by the vCenter vRouter.
  • SNAT:
    • A vCenter vRouter provides the source network address translation (SNAT) service to vCenter VM instances.
    • vCenter VM instances can directly access the Internet by using SNAT.
  • EIP: Allows a vCenter vRouter to access the private network of a vCenter VM instance through a public network.
  • Port forwarding: Forwards the port traffics of a specified public IP address to the port of a corresponding vCenter VM IP address.
  • Load balancing: Distributes inbound traffics from a public IP address to a group of backend vCenter VM instances, and then automatically detects and isolates unavailable vCenter VM instances.
  • IPsec tunnel: Uses the IPsec tunnel protocol to provide site-to-site VPN connections.

ZStack supports multi-tenant management in a managed vCenter. Normal accounts and project members can use vCenter network services, including EIP, port forwarding, and load balancing.

云盘

In vCenter, a volume provides storages for vCenter VM instances. A volume can either be a root volume or a data volume.
  • Root volume: a system disk where the VM instance operating system is installed.
  • Data volume: a data disk that provides additional storages for a VM instance.

vCenter云盘管理主要涉及vCenter数据云盘的管理。

镜像

ZStack Cloud支持添加vmdk格式的本地镜像到vCenter。通过同步数据，vCenter镜像在本地和远端实现状态同步。支持添加两种镜像类型：系统镜像和云盘镜像。

事件消息

The Event Message feature allows you to check vCenter alarm messages, such as the message description, type, the vCenter from which the event message is sent, triggered user, target, and date.
  • The UI can display up to 300 event messages. You can set a time range to check alarm messages within the time range via the time adjustment button at the upper left.
  • You can choose to display alarm message count for each page via the display count button at the upper right. Optional value: 10 | 20 | 50 | 100. In addition, you can turn pages by clicking the left arrow button and the right arrow button.
