###==========================###
/usr/bin/python2 manage.py createsuperuser #添加管理员账号（同样使用python2版本执行，不要使用默认的python执行）
注意此处用默认的python执行上面命令，一般会报错，如下：
ImportError: No module named django.core.management
这个一般是由于python版本引起的，因为系统自带有好几个版本的python
[root@openstack webvirtmgr]# python //按Tab键自查找
python python2.6
python2 python2.6-config python-config
[root@openstack webvirtmgr]# python -V
Python 2.6.6
由此可看出，系统默认的Python版本是2.6.6
说明上面命令默认是python2.6执行的
既然使用python2.6执行上面的命令报错，那就换用其他版本python2执行（如果当前是python3.3.0，那么就将下面的/usr/bin/python2换成/usr/bin/python2.6）

这里用超级管理员登陆，只有超级管理员登陆后才能看到“基础构架”窗口
普通用户登陆后，只能看到“WebVirtMgr”一个窗口
选择“SSH链接“，设置Label，IP，用户
注意：Label与IP要相同
以下为部分网友出现报错：
打开后，有报错！看来在上面使用ssh连接的配置环节有误所致！
解决措施：
1)在webvirtmgr服务器（服务端）上（这里kvm和WebVirtMgr部署在同一台机器上）创建nginx用户家目录（默认nginx服务安装时是没有nginx家目录的），生成nginx的公私钥
[root@openstack ops]# cd /home/
[root@openstack home]# mkdir nginx
[root@openstack home]# chown nginx.nginx nginx/
[root@openstack home]# chmod 700 nginx/ -R
[root@openstack home]# su - nginx -s /bin/bash
-bash-4.1$ ssh-keygen #期间输入yes后直接回车，回车
-bash-4.1$ touch ~/.ssh/config && echo -e "StrictHostKeyChecking=no\nUserKnownHostsFile=/dev/null" >> ~/.ssh/config
-bash-4.1$ chmod 0600 ~/.ssh/config
2)在kvm（客服端）服务器上（这里kvm和WebVirtMgr部署在同一台机器上）配置用户，这里默认采用root用户
---------------------------------------------------------------------------------------------------------------------
如果采用其他用户，比如webvirtmgr，操作如下:
[root@openstack ops]#useradd webvirtmgr
[root@openstack ops]#echo "123456" | passwd --stdin webvirtmgr
[root@openstack ops]#groupadd libvirt
[root@openstack ops]#usermod -G libvirt -a webvirtmgr
---------------------------------------------------------------------------------------------------------------------
3)在webvirtmgr服务器（服务端）上（这里kvm和WebVirtMgr部署在同一台机器上），将nginx用户的ssh-key上传到kvm服务器上（这里kvm和WebVirtMgr部署在同一台机器上）
[root@openstack ops]# su - nginx -s /bin/bash
-bash-4.1$ ssh-copy-id root@192.168.1.17
Warning: Permanently added '192.168.1.17' (RSA) to the list of known hosts.
root@192.168.1.17's password: #输入192.168.1.17即本机的root账号
Now try logging into the machine, with "ssh 'root@192.168.1.17'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
---------------------------------------------------------------------------------------------------------------------
这里采用的是root用户，如果采用其他用户，比如上面假设的webvirtmgr用户，操作如下:
[root@openstack ops]#su - nginx -s /bin/bash
-bash-4.1$ssh-copy-id webvirtmgr@192.168.0.23
---------------------------------------------------------------------------------------------------------------------
4）在kvm（客服端）服务器上（这里kvm和WebVirtMgr部署在同一台机器上）配置 libvirt ssh授权
[root@openstack ops]# vim /etc/polkit-1/localauthority/50-local.d/50-libvirt-remote-access.pkla
[Remote libvirt SSH access]
Identity=unix-user:root #注意这里采用的是root用户
Action=org.libvirt.unix.manage
ResultAny=yes
ResultInactive=yes
ResultActive=yes
[root@openstack ops]# chown -R root.root /etc/polkit-1/localauthority/50-local.d/50-libvirt-remote-access.pkla
-------------------------------------------------------------------------------------------------------------------------------
这里采用的是root用户，如果采用其他用户，比如上面假设的webvirtmgr用户，操作如下:
[root@openstack ops]#vim /etc/polkit-1/localauthority/50-local.d/50-libvirt-remote-access.pkla
[Remote libvirt SSH access]
Identity=unix-user:webvirtmgr #这里就设定webvirtmgr用户
Action=org.libvirt.unix.manage
ResultAny=yes
ResultInactive=yes
ResultActive=yes
[root@openstack ops]#chown -R webvirtmgr.webvirtmgr /etc/polkit-1/localauthority/50-local.d/50-libvirt-remote-access.pkla
--------------------------------------------------------------------------------------------------------------------------------
5）重启 libvirtd 服务
/etc/init.d/libvirtd restart
web创建虚拟机；
1：首先创建iso目录和虚拟机文件的存储目录
3：创建虚拟机
