虛擬化技術，雲計算等概念如火如荼的發展着，然而，在我自身的應用領域卻還沒有開始使用。爲此，我諮詢了VMWare的工程師，他說了一句讓我渾身一冷的話，“沒有集中式存儲就沒有虛擬化”。由於在部署的應用中採用的仍然是傳統的本地存儲，因此我不得不打消虛擬化的念頭。隨着日子的推移，虛擬化在我腦海中揮之不去。我突然想起了國外的同事，就給他寫了封郵件，如下：
Hi:
Long time no see. Hope you still remember me.Now i graduated and work also in an institute as same role like you to be a system administrator.
Currently i am working on puting a bunch of servers together. I want to bring the virtual machine to the system but don't know how. Do you have any experience to share?thanks for your kindness first.
Regards,
Daniel
他的回覆如下：
Hi Daniel,
We use KVM/+libvirt for our virtual machines here and have been quite
happy with it. We use lvm to set up raw partitions for the virtual
drives. All of this is running under Redhat Linux.
Cheers,
Key
根據他的應用經驗，我通過圖形化界面安裝了KVM，但還沒有使用LVM進行原始的分區。RHLinux上圖形化安裝KVM的教程網上很多，需要注意的是，如果修改虛擬機的硬件配置，比如網卡等，需要關閉虛擬機的前提才能操作。
