+====== CentOS6 KVM 使用 console 模式建立 VM ======
+之前都透過 X Win 下的 virt-manager 來建立 VM , 當無法啟用 X Win 的環境下, 就需要透過文字命令模式建立 VM
+  * 環境 Host : CentOS 6.8 x86_64
+  * 預計建立 Guest : CentOS 7 x86_64
+===== 建立 VM 程序 =====
+  * 預計建立 ever-test-3 , 1 vCPU/1G RAM/20G HD , CDROM:/home/ISO/CentOS-7-x86_64-Minimal-1511.iso , 有兩個網卡分別接上 host 的 br0 與 br1
+  * 先建立 20G Disk Image file 在 /kvm/image/ever-test-3.qcow2<code sh>
+qemu-img create -f qcow2 -o preallocation=off /kvm/image/ever-test-3.qcow2 20G
+</code><file>
+[root@HP-ML10G9 ~]# qemu-img create -f qcow2 -o preallocation=off /kvm/image/ever-test-3.qcow2 20G
+Formatting '/kvm/image/ever-test-3.qcow2', fmt=qcow2 size=21474836480 encryption=off cluster_size=65536 preallocation='off'
+[root@HP-ML10G9 ~]# ls -lt /kvm/image/ever-test-3.qcow2
+-rw-r--r-- 1 root root 197120 2016-11-08 09:18 /kvm/image/ever-test-3.qcow2
+</file>
+  * 建立 VM 與光碟安裝 CentOS 7<code sh>
+virt-install --name ever-test-3 --vcpu 1 --ram 1024 --os-type linux --disk /kvm/image/ever-test-3.qcow2,device=disk,bus=virtio,format=qcow2,size=20 --network bridge:br0 --network bridge:br1 --cdrom /home/ISO/CentOS-7-x86_64-Minimal-1511.iso
+</code>{{:tech:kvm-install-01.png}}
+  * 按下 [tab] 增加 linux kernel 開機參數 console=ttyS0,115200 \\ {{:tech:kvm-install-02.png}}
+  * 進入 CentOS7 光碟安裝程序 \\ {{:tech:kvm-install-03.png?750}}
