挂载存储
创建挂载点：
# mkdir /secondary
挂载：
# mount -t nfs 192.168.100.90:/export/secondary /secondary
查看挂载情况：
# df -h

导入系统VM模板
# /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /secondary -u http://d21ifhcun6b1t2.cloudfront.net/templates/4.2/systemvmtemplate-2013-06-12-master-kvm.qcow2.bz2 -h kvm -s -F
If you are using a separate NFS server, perform this step. If you are using the Management Server as the NFS server, you MUST NOT perform this step.
When the script has finished, unmount secondary storage and remove the created directory.
# umount /mnt/secondary
# rmdir /mnt/secondary
也可先下载到本地，然后再导入到二级存储中：
# /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /usr/share/vm -u http://d21ifhcun6b1t2.cloudfront.net/templates/4.2/systemvmtemplate-2013-06-12-master-kvm.qcow2.bz2 -h kvm -F
# mount -t nfs 192.168.100.90:/export/secondary /secondary
# /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /secondary -f /usr/share/vm/template/tmpl/1/3/69dca355-157c-4693-a8c4-f4c586f946ef.qcow2 -h kvm -F
File /usr/share/cloudstack-common/scripts/storage/secondary/8d616d0d-5e56-402a-85c3-8721ff1a9097.qcow2 does not appear to be compressed

# yum install ntp
# yum install cloudstack-agent
# yum install qemu-kvm
# chkconfig ntpd on
检查kvm模块是否正确加载
# lsmod | grep kvm

计算节点（XenServer）
安装两台XenServer，注意主机名、hosts以及IP地址的设置。
创建环境
首次登录，首先跳过向导设置“全局设置”：
1 设置secstorage.allowed.internal.sites为二级存储所在网段，如192.168.100.0/24
2 若要使用本地存储则将system.vm.use.local.storage设为true
……
修改后重启cloudstack：
# service cloudstack-management restart
向导设置
http://192.168.100.75:8080/client/
用户名：admin
密码：password
点击“继续执行基本安装”
重置密码
添加区域
在区域内添加一个提供点，IP范围用于系统VM
添加剩余节点
上传ISO
在manage节点上直接通过httpd搭建一个网络共享存储
# vim /etc/mime.types
添加一条内容
none/none iso
重启httpd：
# service httpd restart
将iso放入/var/www/html下并赋权：
# chown apache CentOS-6.4-x86_64-bin-DVD1.iso
通过浏览器尝试下载：
http://192.168.100.75/CentOS-6.4-x86_64-bin-DVD1.iso
问题
Q1
# modprobe kvm-amd
FATAL: Error inserting kvm_amd (/lib/modules/2.6.32-431.5.1.el6.x86_64/kernel/arch/x86/kvm/kvm-amd.ko): Operation not supported
# egrep '(vmx|svm)' /proc/cpuinfo
未有输出，说明当前系统cpu不支持虚拟化
Q2
# /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /secondary -u http://d21ifhcun6b1t2.cloudfront.net/templates/4.2/systemvmtemplate-2013-06-12-master-kvm.qcow2.bz2 -h kvm -s -F
