如何使用 pyvmomi 以编程方式更改 E1000e 网络接口？

如何解决如何使用 pyvmomi 以编程方式更改 E1000e 网络接口？

我正在使用脚本将虚拟机恢复到 vCenter 7.0U1 以进行灾难恢复。该脚本将网卡更改为基于之前的新端口组密钥指向新的端口组密钥。该脚本适用于 VMXNET3 和 E1000 网卡，但是当出现 E1000e 网卡时，脚本运行成功，并且 vmware 报告：“指定的参数不正确”

我已将 pyvmomi 更新到 7.0.2，将 pyvim 更新到 3.0.2 以排除版本问题。

我在 CentOS 7.9 上使用 python3.6

这是分配网卡的代码：

        for device in custvm.config.hardware.device:
        if isinstance(device,vim.vm.device.VirtualEthernetCard):
            print("old")
            print(device)
            devcount = devcount + 1
            syslog.syslog(syslog.LOG_INFO,guest['vmname']+": VirtualEthernetCard found with MAC: "+str(device.macAddress))
            try:
                dstnetname = snapshotNetworkData[devcount]['dstnetname']
            except:
                syslog.syslog(syslog.LOG_ERR,guest['vmname']+": Failed to load snapshotNetworkData--Defaulting to first targetNetwork")
                if len(snapshotNetworkData) == 0:
                    dstnetname = runbook['Runbook'][0]['Networks'][0]['targetVmxNet']
            syslog.syslog(syslog.LOG_INFO,guest['vmname']+": Determined Destination to be: "+dstnetname)
            dstnetwork = get_obj(vcContentDR,[vim.dvs.distributedVirtualPortgroup],dstnetname)
            syslog.syslog(syslog.LOG_INFO,guest['vmname']+": pulled object "+str(dstnetwork.key))
            nicspec = vim.vm.device.VirtualDeviceSpec()
            nicspec.operation = vim.vm.device.VirtualDeviceSpec.Operation.edit
            if snapshotNetworkData[devcount]['deviceType'] == "com.vmware.vim25.VirtualE1000e":
                nicspec.device = vim.vm.device.VirtualE1000e()
                nicspec.device.key = device.key
                nicspec.device.controllerKey = device.controllerKey
                nicspec.device.unitNumber = device.unitNumber
                nicspec.device.addresstype = 'assigned'
                nicspec.device.deviceInfo = device.deviceInfo
            else:
                nicspec.device = device
            nicspec.device.wakeOnLanEnabled = False
            try:
                nicspec.device.macAddress = snapshotNetworkData[devcount]['macAddress']
            except:
                nicspec.device.macAddress = str(device.macAddress)
            dvs_port_connection.append(vim.dvs.PortConnection())
            dvs_port_connection[devcount].portgroupKey = dstnetwork.key
            dvs_port_connection[devcount].switchUuid = dstnetwork.config.distributedVirtualSwitch.uuid
            nicspec.device.backing = vim.vm.device.VirtualEthernetCard.distributedVirtualPortbackingInfo()
            nicspec.device.backing.port = dvs_port_connection[devcount]
            nicspec.device.connectable = vim.vm.device.VirtualDevice.ConnectInfo()
            nicspec.device.connectable.allowGuestControl = True
            nicspec.device.connectable.startConnected = True
            nicspec.device.deviceInfo.summary = dstnetname
            device_change.append(nicspec)
            print("new")
            print(dstnetname)
            print(nicspec)
            syslog.syslog(syslog.LOG_INFO,str(nicspec))
    config_spec = vim.vm.ConfigSpec(deviceChange=device_change)
    task = custvm.ReconfigVM_Task(config_spec)

以下是“nicspec”变量的输出，显示了提交给 vCenter 的内容：

    (vim.vm.device.VirtualDeviceSpec) {
   dynamicType = <unset>,dynamicProperty = (vmodl.DynamicProperty) [],operation = 'edit',fileOperation = <unset>,device = (vim.vm.device.VirtualE1000e) {
      dynamicType = <unset>,key = 4000,deviceInfo = (vim.Description) {
         dynamicType = <unset>,label = 'Network adapter 1',summary = '221d cust021-10GNNetwork'
      },backing = (vim.vm.device.VirtualEthernetCard.distributedVirtualPortbackingInfo) {
         dynamicType = <unset>,port = (vim.dvs.PortConnection) {
            dynamicType = <unset>,switchUuid = '50 1a fc 33 0b aa 6d 19-38 24 a1 8c 9f 4f 11 1f',portgroupKey = 'dvportgroup-10330',portKey = <unset>,connectionCookie = <unset>
         }
      },connectable = (vim.vm.device.VirtualDevice.ConnectInfo) {
         dynamicType = <unset>,migrateConnect = <unset>,startConnected = true,allowGuestControl = true,connected = false,status = <unset>
      },slotInfo = <unset>,controllerKey = 100,unitNumber = 7,addresstype = 'assigned',macAddress = '**:**:**:**:**:**',wakeOnLanEnabled = false,resourceAllocation = <unset>,externalId = <unset>,uptCompatibilityEnabled = <unset>
   },profile = (vim.vm.ProfileSpec) [],backing = <unset>
}

如果有任何其他故障排除所需的信息，请告诉我。
