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）
