dell webcam
先vmware設定當中選中usb相關的三個選項
然後啟動相應的虛擬機器系統
先lsusb找不到之後
虛擬機器->可移動裝置->攝像頭裝置（microdia integrated webcam_hd）->斷開連線（連線主機）
然後快速在終端輸入dmesg

找到了usb攝像頭裝置bus 003 device 007: id 0c45:671f microdia
那麼就可以使用了,
然後系統就重新檢測裝置，找到了筆記本自帶的usb

KVM巢狀虛擬化 在虛擬機器中建立虛擬機器
一般情況下，我們是無法在kvm虛擬機器裡面再去建立虛擬機器的，因為我們的kvm虛擬機器的cpu預設情況下並不支援虛擬化功能，對於inter的cpu來說，如果要支援虛擬化功能，必須要有乙個叫vmx的特性，以下是乙個物理伺服器的cpu資訊 在cpu特性 flags 中包含了vmx這個特性，說明這台伺服器...
