使用powercli创建模板与克隆虚机
用powercli练练手,需从实际案例出发,本节将使用powercli写两个demo,一个是创建模板,并根据模板创建新的虚机;另一个demo是克隆虚机。
【注意】
1、创建模板与克隆操作只能在vcenter上使用
2、powercli是 异步任务,因此需等待一个任务完成后,再去执行下一个任务。(使用 -Runasync 与 -ErrorAction stop 类似于linux中的nohup与&的使用)
一、创建模板并根据模板生成虚机
$task = Stop-VM win -Confirm:$false -ErrorAction Stop -RunAsync #停止虚机,并放后台 while( $task.state -eq "Running" ) #使用while循环时刻监控上一任务是否结束 { $task = Get-Task -ID $task.id } $task1 = New-Template -VM ( Get-VM win2 ) -Name "tp" -Location "nickdc" -ErrorAction Stop -RunAsync #根据虚机创建模板 while( $task1.state -eq "Running" ) { $task1 = Get-Task -ID $task1.id } #根据模板创建虚机 $task2 = New-VM -Name win3 -Template ( Get-Template tp) -VMHost (Get-VMHost 10.32.2.99) -Datastore (Get-Datastore datastore1) -ResourcePool testpool -ErrorAction Stop -RunAsync while( $task2.state -eq "Running" ) { $task2 = Get-Task -ID $task2.id } Start-vm win3 #开启虚机
二、克隆虚机
脚本过程:确认虚机名与虚机所在的磁盘--> 连接vcenter-->关闭虚机-->克隆虚机-->开启虚机
$eap = $ErrorActionPreference Try{ $ErrorActionPreference = 'Stop' # set vm name & clone vm name $sourcevmname = "abcd" $clonevmname = "123" # check vm name $tip1 = Read-Host "make sure source vm name is $sourcevmname , if true , input 'y/Y' " $tip2 = Read-Host "make sure clone vm name $clonevmname , if true , input 'y/Y'" if ( $tip1 -eq "y|Y" -and $tip2 -eq "y|Y" ) { echo "please make sure vm name " exit 1 } #connect vcentr $vcenterip = "8.8.8.8" $user = "administrator@vsphere.com" $passwd = "123456" Connect-VIServer $vcenterip -User $user -Password $passwd -SaveCredentials sleep 20 $starttime = date -Format "HH:mm:ss" echo "start time : $starttime" #shutdown vm echo (get-vm $sourcevmname).PowerState if( (get-vm $sourcevmname).PowerState -eq "PoweredOn" ) { stop-vm $sourcevmname -Confirm:$false echo "stop vm" sleep 30 } #clone vm $myDatastore = Get-Datastore -Name datastore1 $vmhost = Get-VMHost -Name 10.32.2.99 $pool = Get-ResourcePool -Name testpool echo "start clone vm..." $task = New-VM -Name $clonevmname -VM $sourcevmname -Datastore $myDatastore -VMHost $vmhost -ResourcePool $pool -RunAsync -ErrorAction Stop while( $task.state -eq "Running" ) { $task = Get-Task -ID $task.id } echo "clone ok!" sleep 5 #start vm echo "start vm" start-vm $clonevmname echo "everything ok!" $usetime = (New-TimeSpan $starttime ).TotalMinutes $msg = "clone take {0:n0} minutes" -f $usetime echo $msg } Catch{ Write-Host "error !" Exit 1 } Finally{ $ErrorActionPreference = $eap }
