线程没有创建多个虚拟机（会话问题）

数据从* .csv文件拍摄。脚本应该在我的测试用例中创建2个虚拟机，但是在不同的线程中。需要指导如何解决这个问题。线程没有创建多个虚拟机（会话问题）

cls 

Add-PSSnapin VMware.VimAutomation.Core | Out-Null 

#import VM settings 
$VMs = Import-CSV '...\Data.csv' -UseCulture 

#array for connections 
$server = @() 
#threads 
$Throttle = 2 

# Create session state 
$sessionState = [System.Management.Automation.Runspaces.InitialSessionState]::CreateDefault() 

# Create runspace pool consisting of runspaces 
$RunspacePool = [RunspaceFactory]::CreateRunspacePool(1, $Throttle, $sessionState, $Host)

    Write-Host $VM.vm_name "Father session: " $ses.SessionSecret 

    $sessionf = Connect-VIServer $VM.vs_xstream__vc_host -Session $ses.SessionSecret -wa 0

    $domain_name = $VM.FQDN.split('.')

} 

Write-Host ("Starting script: {0}" -f (Get-Date)) 
$startTime = Get-Date 

$count = 0 
ForEach($VM in $VMs) 
{ 
    $count = $count + 1 

    Write-Host $VM.vs_xstream__vc_host 

    Write-Host "Current connections:" 
    $Global:DefaultVIServers.count 

    $ses = Connect-VIServer $VM.vs_xstream__vc_host -User $VM.vs_xstream__vc_admin -Password $VM.vs_xstream__vc_password -wa 0 

    $Job = [powershell]::create() 
    $Job.RunspacePool = $RunspacePool 
    $Job.AddScript($ScriptBlocky).AddParameter("VM", $VM).AddParameter("ses", $ses) 

    Write-Host "Adding job to jobs list" 
    $Jobs += New-Object PSObject -Property @{ 
     RunNum = $count 
     Job = $Job 
     Result = $Job.BeginInvoke() 
     } 

    #Disconnect-VIServer $VM.vs_xstream__vc_host -Confirm:$false -Force 
} 


Write-Host "Waiting.." -NoNewline 
Do { 
    Write-Host "." -NoNewline 
    Start-Sleep -Seconds 1 
} While ($Jobs.Result.IsCompleted -contains $false) 

$endTime = Get-Date 
$totalSeconds = "{0:N4}" -f ($endTime-$startTime).TotalSeconds 
Write-Host "All jobs finished in $totalSeconds seconds"

结果：

..............

作为结果表明因为virtual38是第一线具有会话信息，并且可以执行动作。

也许我错了，这个我觉得会议isssue是防止产生第二VM（virtual39）

更新/通知：我意识到，当线程$油门= 1，则这两个VM创建，当我设置$ Throttle = 2或更多，那么只有其中一个（第一个）被创建。

有什么建议吗？

相信我，或没有，但我发现什么是错误的。脚本正在工作，但是当连接到新会话或现有的会话（甚至是不同的vCenter，需要在多个vCenter环境中创建虚拟机时），DefaultVIServers变量会被修改，会话将会丢失。

解决方案： *创建所有其他行动之前，所有连接到vCenter的连接，以便将保持稳定。例如：所有的工作已经完成

# Iterate and connect to all vCenters so connections to them will be stable and read only 
ForEach($VM in $VMs) 
{ 
    If ($VM.Use -eq 1) 
    { 
     If($server.Contains($VM.vs_xstream__vc_host) -eq $FALSE) 
     { 
     $server += $VM.vs_xstream__vc_host 
     $AllSessions += Connect-VIServer $VM.vs_xstream__vc_host -User $VM.vs_xstream__vc_admin -Password $VM.vs_xstream__vc_password -NotDefault 
     Write-Host "Connected to: " $VM.vs_xstream__vc_host 
     } 
    } 
}

后，我简单地从所有会话

# Disconnect all created sessions 
ForEach($item in $server) 
{ 
    Write-Host ("Disconnecting from {0}...." -f ($item)) 
    Disconnect-VIServer $item -Confirm:$false 
}

断开现在脚本完美的作品，并在不同或相同的vCenter创建VM。如果有人会遇到任何问题，请告诉我。
