虚拟机运行在ESXi之上，是虚拟机稳定运行的基础
1、
# pick a particular host./选择特定主机 $h = get-vmhost 10.132.97.19
2、
# Let's take a look at advanced configuration options. #查看主机高级配置，非常多参数，所以带个more会按照窗口显示 $h | Get-VMHostAdvancedConfiguration | more
3、
# That's a lot of stuff! How many options are there exactly? #非常多参数，有多少选项是你需要的选择的 $h | Get-VMHostAdvancedConfiguration | Measure-Object
4、
# That's not right??? Something is funny about the object. Let's take a closer look at it. #如果没有你需要的，我们可以更精细的查看 $config = $h | Get-VMHostAdvancedConfiguration $config | Get-Member
5、
# How do we get a specific value? 来看下我们怎样获取一些指定的参数值 $config."Cpu.MoveCurrentRunnerPcpus"
6、
# Let's count the number of advanced options. #让我们来统计高级选项的数量 $config.Keys | measure-object
7、
# Use case: NFS tuning.
# Let's set the max NFS heartbeat failures to 20 across all our hosts.
$h | Get-VMHostAdvancedConfiguration | select -expand Keys | Where { $_ -like "NFS*" }
8、
# Now let's change some settings. # Set-VMHostAdvancedConfiguration is easy compared to Get- # Get-VMHost | Set-VMHostAdvancedConfiguration -name NFS.HeartbeatMaxFailures -Value 10
9、
# Increase the heap size to 30mb.这些命令都比较方便，不用在图形界面点过来点过去， #为后期的自动化脚本实现提供基础命令 Get-VMHost | Set-VMHostAdvancedConfiguration -name Net.TcpipHeapSize -Value 30
10、
# Setting DNS is easy with Set-VMHostNetwork Get-VMHost | Get-VMHostNetwork | Set-VMHostNetwork -DnsAddress 10.132.97.25
# Hostname, ConsoleGateway, DNSAddress , IP, SubnetMask, ConsoleGateway, DNSAddress, Devicename 选择的参数非常之多 Get-VMHost | Get-VMHostNetwork | Select Hostname, PortGroupName, IP
谢谢，感兴趣可以继续跟文。
