Citrix XenServer Tools作用

   之前一直在糾結xen-tools的作用，今天偶然在官方資料上瞄到了：  

   xenserver tools must be installed for each virtual machine (windows and linux) in order for the vm to have a fully supported configuration, and to be able to use the xenserver management tools (the xe cli or xencenter).

   a windows vm will function without them, but performance will be significantly hampered unless the tools are installed./不安裝也能運作，但是性能在很大程度上會被限制

without the tools being installed, you cannot:

• cleanly shut down a vm /幹淨利落的關閉一台虛拟機

• cleanly reboot a vm /幹淨利落的重新開機一台虛拟機

• suspend a vm /挂起一台虛拟機

• migrate a running vm (xenmotion) /利用xenmotion遷移一台正在運作的虛拟機

• use the checkpoint and roll back feature /使用快照和從快照恢複功能

• dynamically adjust the number of vcpus assigned to a running linux vm- windows vms require a reboot for this to take effect /動态調整vcpu數量，需要重新開機才能生效

for further information about xenserver tools see the section called “xenserver tools”

warning:

running a vm without installing the xenserver tools is not a supported configuration.

/運作一台不安裝xen-tools的虛拟機是不建議的配置
