oVirt上创建Windows的虚拟机的驱动问题

oVirt在创建虚拟机时，可以选择虚拟机磁盘类型，如果采用IDE模式，一般的windows可以在安装时识别到虚拟磁盘，但在这种情况下，IO性能比较低。在创建虚拟机时，如果使用virtio的方式可以提高虚拟机IO性能，virtio所驱动的网卡，也将原来的百兆扩展到千兆。

1、安装virtio驱动

# wget https://fedorapeople.org/groups/virt/virtio-win/virtio-win.repo -O /etc/yum.repos.d/virtio-win.repo

# yum install virtio-win -y

# rpm -ql virtio-win | grep iso 
/usr/share/virtio-win/virtio-win-0.1.160.iso 
/usr/share/virtio-win/virtio-win.iso

# pwd
/usr/share/virtio-win

# ll
total 321036
drwxr-xr-x 4 root root        31 Nov 21 16:22 drivers
drwxr-xr-x 2 root root        52 Nov 21 16:22 guest-agent
-rw-r--r-- 1 root root   2949120 Aug 16 04:57 virtio-win-0.1.160_amd64.vfd
-rw-r--r-- 1 root root 322842624 Aug 16 04:59 virtio-win-0.1.160.iso
-rw-r--r-- 1 root root   2949120 Aug 16 04:57 virtio-win-0.1.160_x86.vfd
lrwxrwxrwx 1 root root        28 Nov 21 16:22 virtio-win_amd64.vfd -> virtio-win-0.1.160_amd64.vfd
lrwxrwxrwx 1 root root        22 Nov 21 16:22 virtio-win.iso -> virtio-win-0.1.160.iso
lrwxrwxrwx 1 root root        26 Nov 21 16:22 virtio-win_x86.vfd -> virtio-win-0.1.160_x86.vfd

2、手工下载驱动

目前最新版本为virtio-win-0.1.160

https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.160-1/

3.上传驱动文件

     找到配置的ISO存储域，并将virtio-win-0.1.160_amd64.vfd、virtio-win-0.1.160.iso、virtio-win-0.1.160_x86.vfd文件拷贝到对应目录

 #  cp /tmp/virtio-win-* /iso/42764683-5ef1-45ea-9b5a-fd89765b3c4e/images/11111111-1111-1111-1111-111111111111/

4.在windows系统安装时加载VirtIO驱动

1. 点击 Compute → Virtual Machines.

2. 点击 Run → Run Once.

3. 打开 Boot Options 菜单

4. 选择Attach Floppy下拉框并选择virtio-win.vfd.

5. 选择Attach CD下拉框并选择window的iso文件

6. 将 CD-ROM设置为第一启动引导项

7. 配置其他需要的 Run Once 选项

8. 点击 OK.

5.在windows系统安装虚拟设备驱动

1. 点击 Compute → Virtual Machines.

2. 点击 Run → Run Once.

3. 打开 Boot Options 菜单

4. 选择Attach CD下拉框并选择virtio-win-0.1.160.iso文件

5. 将 CD-ROM设置为第二启动引导项

6. 配置其他需要的 Run Once 选项

7. 点击 OK.

8. 虚拟机启动后，在电脑 →属性 →设备管理器中选择未识别的硬件，然后更新驱动程序，选择在CD-ROM下进行扫描安装即可
