OpenStack連接vCenter，通過其的API發送指令，datastore作為glance和cinder的存儲后端，nova將其整個集群作為虛擬化后端，一個nova-compute只能連接一個vCenter，但是可以指定多個vCenter下的集群。

本文涉及到的環境

• CentOS Linux release 7.2.1511
• OpenStack Liberty
• vCenter6.0.0

OpenStack連接VC拓撲圖

Nova連接VC配置

[default] compute_driver=vmwareapi.VMwareVCDriver [vmware] host_ip=192.168.4.99 host_username=administrator@vsphere.local host_password=!QAZ2wsx cluster_name=cluster datastore_regex=datastore1 wsdl_location=https://192.168.4.99/sdk/vimService.wsdl insecure=True

Cinder連接VC配置

# Storage backend default_volume_type = vmware enabled_backends = vmware # volume driver configuration [vmware] volume_driver=cinder.volume.drivers.vmware.vmdk.VMwareVcVmdkDriver vmware_host_ip=192.168.4.99 vmware_host_username=administrator@vsphere.local vmware_host_password=!QAZ2wsx vmware_wsdl_location=https://192.168.4.99/sdk/vimService.wsdl # vmware_cluster_name = cluster vmware_insecure = True vmware_volume_folder = Volumes

Glance配置

• glance-api配置

  [glance_store] default_store=vsphere stores=vmware,http vmware_server_host=192.1681.4.99 vmware_server_username=administrator@vsphere.local vmware_server_password=!QAZ2wsx vmware_datastores = datacenter:datastore1 vmware_api_insecure = True vmware_task_poll_interval = 5 vmware_store_image_dir = /openstack_glance [paste_deploy] flavor=keystone config_file=/usr/share/glance/glance-api-dist-paste.ini

• glance-registry配置

  [paste_deploy] flavor=keystone config_file=/usr/share/glance/glance-registry-dist-paste.ini

  [glance_store] default_store = vsphere stores = vmware,http vmware_server_host=192.168.4.99 vmware_server_username=administrator@vsphere.local vmware_server_password=!QAZ2wsx vmware_datacenter_path=datacenter vmware_datastore_name=datastore1

上傳鏡像到datestore

• 通過glance上傳鏡像，用head -n 20 *.vmdk查看那鏡像的格式,如果是從qcow2/raw轉成vmdk鏡像，用如下命令上傳鏡像到datastore

  glance image-create --progress --name centos_vmdk --container-format bare --disk-format vmdk --property vmware_adaptertype=ide --property vmware_disktype=sparse < centos.vmdk
