测试环境

OpenStack Liberty: 双节点(192.168.1.1/192.168.1.2), 后续内容中分别以 node1/node2 表示双节点.

vCenter 环境:

• VMware vCenter Server Application(192.168.1.100) 账号: root/vmware
• vCenter 层级结构:

vCenter     ==> Datacenter-1(datastore1)         ==> Cluster-1             ==> Host(192.168.1.3)

Nova 配置(OpenStack 纳管 vCenter 虚拟机)

使用 vCenter 驱动配置.

现阶段而言, OpenStack 对 vCenter 虚拟机的管理包括 虚拟机的创建/删除/启停/休眠/唤醒/挂起/迁移 等. 但一些高级的 vCenter 功能如 DRS/DAS 等仍然不被支持.

• node1: vim /etc/nova/nova.conf

[DEFAULT]...force_config_drive=True...config_drive_format=iso9660compute_driver=vmwareapi.VMwareVCDriver[vmware]host_ip=192.168.1.100host_username=roothost_password=vmwarecluster_name=Cluster-1datastore_regex=datastore1wsdl_location=https://192.168.1.100/sdk/vimService.wsdlinsecure=True

• node2: vim /etc/nova/nova.conf

[DEFAULT]...force_config_drive=Trueconfig_drive_format=iso9660...compute_driver=vmwareapi.VMwareVCDriver[vmware]host_ip=192.168.1.100host_username=roothost_password=vmwarecluster_name=Cluster-1datastore_regex=datastore1wsdl_location=https://192.168.1.100/sdk/vimService.wsdlinsecure=True

Glance 配置(OpenStack 纳管 vCenter 镜像)

实际上在接入 vCenter 之后, Glance 的镜像仍能够存放在本地, 但当 vCenter 需要使用这个镜像来启动一个虚拟机时, 首先会将本地的镜像文件上传到 vCenter Datastore 之后才能开始创建, 相当耗时, 所以建议将镜像文件都上传到 Datastore 中.

OpenStack 对 vCenter 镜像的管理包括: 上传/下载 等功能.

• node1: vim /etc/glance/glance-api.conf

[DEFAULT]...known_stores = vmwaredefault_store = vsphere[glance_store]stores = file,http,vmwarevmware_server_host = 192.168.1.100vmware_server_username = rootvmware_server_password = vmwarevmware_datastore_name = datastore1vmware_datacenter_path = Datacenter-1vmware_datastores = Datacenter-1:datastore1vmware_task_poll_interval = 5vmware_store_image_dir = /openstack_glancevmware_api_insecure = True

Cinder 配置(OpenStack 纳管 vCenter 块设备)

其实这里与其说是 OpenStack 纳管 vCenter 块设备 不如说是 OpenStack Cinder 为 vCenter 提供块设备功能. 换句话来说, vCenter 能够使用 Cinder 提供的 Volumes 来创建虚拟机和作为存储使用. 除此之外, Cinder 仍能保持对块存储的管理功能, 如: Volumes 的 创建/删除/快照/挂载/卸载 等. 有以下两点需要注意:

1. Volumes 的挂载与卸载操作需要关闭虚拟机电源

2. Cinder 不支持 Volumes 的备份功能

   • node1: vim /etc/cinder/cinder.conf

[DEFAULT]...default_volume_type = vmwareenabled_backends = vmware[vmware]vmware_insecure=Truevmware_host_ip=192.168.1.100vmware_host_username=rootvmware_host_password=vmwarevmware_volume_folder=Volumesvmware_wsdl_location=https://192.168.1.100/sdk/vimService.wsdlvolume_driver=cinder.volume.drivers.vmware.vmdk.VMwareVcVmdkDrivervmware_insecure = True

• node2: vim /etc/cinder/cinder.conf

[DEFAULT]...default_volume_type = vmwareenabled_backends = vmware[vmware]vmware_insecure = truevmware_host_ip=192.168.1.100vmware_host_username=rootvmware_host_password=vmwarevmware_wsdl_location=https://192.168.1.100/sdk/vimService.wsdlvolume_driver = cinder.volume.drivers.vmware.vmdk.VMwareVcVmdkDrivervmware_insecure = True

NOTE: 需要创建名为 vmware 的类型

cinder type-create vmware

Ceilometer 配置

VMware 暴露的监控最小采集频率是 300s, OpenStack Ceilometer 目前仅提供了对虚拟机的监控能力, 但能够通过其他的 vSphere API 来拿到更多 Datacenter/Cluster/Host/VirtualMachine 的 runtime information, 基本上包含了 CPU/Mem/DiskIO/网络流量 四个常规的监控对象.

• node1: vim /etc/ceilometer/ceilometer.conf

[DEFAULT]...hypervisor_inspector=vsphere[node]virt_inspector=vmware[vmware]host_ip=192.168.1.100host_username=roothost_password=vmwarewsdl_location=https://192.168.1.100/sdk/vimService.wsdlinsecure=True[service_credentials]# 如果是多region，请更改下面配置项#os_region_name = 
   

• node2: vim /etc/ceilometer/ceilometer.conf

[DEFAULT]...hypervisor_inspector=vsphere[node]virt_inspector=vmware[vmware]host_ip=192.168.1.100host_username=roothost_password=vmwarewsdl_location=https://192.168.1.100/sdk/vimService.wsdlinsecure=True[service_credentials]# 如果是多region，请更改下面配置项#os_region_name = 
   

测试

• Step1: 重启相关服务

# node1 systemctl restart openstack-nova-compute.service openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.servicesystemctl restart openstack-glance-api.servicesystemctl restart openstack-cinder-api.service openstack-cinder-volume.servicesystemctl restart openstack-ceilometer-collector.service openstack-ceilometer-api.service# node2systemctl restart openstack-nova-compute.service openstack-nova-api.servicesystemctl restart openstack-cinder-api.service openstack-cinder-volume.servicesystemctl restart openstack-ceilometer-collector.service openstack-ceilometer-api.service

• Step2: 尝试上传镜像文件, 在上传镜像的时候, 我们需要注意以下两点:

NOTE 1: 首先需要知道镜像文件的「disktype 和 adaptertype」, 使用指令 head -20 <vmdk_image_file> 就能够查看相关类型.

[root@seed ~]# head -20 cirros-0.3.2-i386-disk.vmdkKDMV�9��# Disk DescriptorFileversion=1CID=5350c0c0parentCID=ffffffffcreateType="monolithicSparse"# Extent descriptionRW 80325 SPARSE "cirros-0.3.2-i386-disk.vmdk"# The Disk Data Base#DDBddb.virtualHWVersion = "4"ddb.geometry.cylinders = "79"ddb.geometry.heads = "16"ddb.geometry.sectors = "63"ddb.adapterType = "ide"      # adaptertype == ide���������

NOTE 2: 如果使用指令 qemu-img 将 qcow2/img 格式的镜像文件转换成 vmdk 格式镜像文件时, vmware_disktype 通常为 sparse, 而 vmware_adaptertype 通常为 ide, 所以相应的可以使用下面的镜像上传指令:

glance image-create \--name fanguiju-test-2 \--container-format bare \--disk-format vmdk \--property vmware_disktype="sparse" \--property vmware_adaptertype="ide" \< cirros-0.3.2-i386-disk.vmdk+--------------------+----------------------------------------------------------------------------------+| Property           | Value                                                                            |+--------------------+----------------------------------------------------------------------------------+| checksum           | 3fd19141ff969dcb4926b610769e5ba4                                                 || container_format   | bare                                                                             || created_at         | 2017-04-19T08:27:25Z                                                             || direct_url         | vsphere://192.168.1.100/folder/openstack_glance/70d581d4-1829-45c1-ac6c-          ||                    | ac1755da1650?dcPath=Datacenter-1&dsName=datastore1                               || disk_format        | vmdk                                                                             || id                 | 70d581d4-1829-45c1-ac6c-ac1755da1650                                             || locations          | [{"url": "vsphere://192.168.1.100/folder/openstack_glance/70d581d4-1829-45c1      ||                    | -ac6c-ac1755da1650?dcPath=Datacenter-1&dsName=datastore1", "metadata": {}}]      || min_disk           | 0                                                                                || min_ram            | 0                                                                                || name               | fanguiju-test                                                                    || owner              | 1774b99ae7374d9b948fb4146fbf49fb                                                 || protected          | False                                                                            || size               | 17104896                                                                         || status             | active                                                                           || tags               | []                                                                               || updated_at         | 2017-04-19T08:27:28Z                                                             || virtual_size       | None                                                                             || visibility         | private                                                                          || vmware_adaptertype | ide                                                                              || vmware_disktype    | sparse                                                                           |+--------------------+----------------------------------------------------------------------------------+

PS: 建议使用测试镜像文件.

NOTE 3: 如果上传镜像文件失败, 并且通过 glance/api.log 看出为 glance_store 相关的 ERROR, 可以尝试升级 glance_store 的版本. L版管理vmware需要升级 glance-store 的步骤:

[root@seed yum.repos.d]# rpm -ivh https://repos.fedorapeople.org/repos/openstack/openstack-mitaka/rdo-release-mitaka-5.noarch.rpm[root@seed yum.repos.d]# vim rdo-release.repo[root@seed yum.repos.d]# yum makecache[root@seed yum.repos.d]# yum update python-glance-store

Datastore 创建了 openstack_glance 目录:

• Step 3: 启动虚拟机

vCenter 任务流:

在 vCenter 中启动成功:

• Step4: 创建 Cinder volumes 后能在 vCenter「虚拟机与模板」界面看到对应的 Volumes, 然后就可以使用这个 Volumes 来创建虚拟机或作为存储使用了.
