实用PowerCLI脚本
连接至vCenter Server或ESXi
Connect-VIServer -Server serverip -username root -Password password #这个在通过程序菜单启动PowerCLI的时候就会提示的
----------------------------
使PowerShell启动时自动加载PowerCLI插件，将以下代码保存为
%UserProfile%\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1
if ((Get-PSSnapin -Name VMware.VimAutomation.Core -ErrorAction SilentlyContinue) -eq $null) {
try {
Write-Host "Loading PowerCLI plugin, this may take a little while" -foregroundcolor "cyan"
Add-PSSnapin VMware.VimAutomation.Core
$PCLIVer = Get-PowerCLIVersion
if ((($PCLIVer.Major * 10 ) + $PCLIVer.Minor) -ge 51) {
$null = Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -confirm:$false -Scope "Session"
}
}
catch {
Write-Host "Unable to load the PowerCLI plugin. Please verify installation or install VMware PowerCLI and run this script again."
Read-Host "Press <Enter> to exit"
exit
}
}
----------------------------
查找vSphere环境中存在快照的虚拟机(Get-VM后面加上指定虚机名称即可查询指定虚机的快照)
Get-VM | Get-Snapshot #显示快照列表
Get-VM | Get-Snapshot | format-list #详细显示快照信息
Get-VM | Get-Snapshot | format-table Created,VM,SizeMB #指定输出列
Get-VM | Get-Snapshot | format-table Created,VM,@{label="SizeGB";Expression={"{0:N2}" -f ($_.SizeMB/1024)}} #将输出单位改为GB，并指定小数位数为2位。5.1版本以后可以用SizeGB代替SizeMB/1024
----------------------------
将指定VM的E1000网卡替换为VMXNET3（KB2059053的临时方案）
Get-VM vmname | Get-NetworkAdapter | Where {$_.Type -eq "E1000"} | Set-NetworkAdapter -Type vmxnet3
--------------------
获取存储对象，并排除掉本地存储（如需筛选输出列，使用Select-Object）
Get-Datastore| Where-Object {$_.Name -notmatch "local|datastore"}
--------------------
PowerCLI 脚本创建10个虚拟机
#************************************
