OpenStack连接vCenter，通过其的API发送指令，datastore作为glance和cinder的存储后端，nova将其整个集群作为虚拟化后端，一个nova-compute只能连接一个vCenter，但是可以指定多个vCenter下的集群。

本文涉及到的环境

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

OpenStack连接VC拓扑图

Nova连接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连接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

上传镜像到datestore

• 通过glance上传镜像，用head -n 20 *.vmdk查看那镜像的格式,如果是从qcow2/raw转成vmdk镜像，用如下命令上传镜像到datastore

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