PowerShell learning------hpyer-v Virtual machine optimization (backup, compressed disk)

Learn about Robin's blog post, the original address   below is his summary automation management is becoming more and more common,hyper-v  virtual machines also can. Premise:   system server 2008 above,powershell 3.0,  import Hyper-V Library 1.

With regard to the use of the actual production, I recommend to perform in idle time. I usually continue after the patch update so after compressing the backup VM, can also automate execution, the ultimate goal is to optimize the Hyper-V virtual machine   Compress -VHD -VHDPaths  ' e:\ Hyperv_runing\vhd\xpx32.vhd '   #compress  vhd  compressed disk   The path to the virtual machine disk: ' E:\HyperV_Runing\VHD\XPx32.vhd ' Get-wmiobject -namespace root\virtualization msvm_storagejob | ft jobstatus,  description, percentcomplete -auto   #compress  status View background compression
