虚拟化技术,云计算等概念如火如荼的发展着,然而,在我自身的应用领域却还没有开始使用。为此,我咨询了VMWare的工程师,他说了一句让我浑身一冷的话,“没有集中式存储就没有虚拟化”。由于在部署的应用中采用的仍然是传统的本地存储,因此我不得不打消虚拟化的念头。随着日子的推移,虚拟化在我脑海中挥之不去。我突然想起了国外的同事,就给他写了封邮件,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
他的回复如下:
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
根据他的应用经验,我通过图形化界面安装了KVM,但还没有使用LVM进行原始的分区。RHLinux上图形化安装KVM的教程网上很多,需要注意的是,如果修改虚拟机的硬件配置,比如网卡等,需要关闭虚拟机的前提才能操作。
