kvm 镜像制作与 ova镜像转换
一、kvm通过iso 安装镜像1、生成空的img文件
qemu-img create -f qcow2 /opt/data/rock-feibiao/slse11-sp4/SLES-11-SP4-DVD-x86_64-GM-DVD1.img -opreallocation=metadata 20G
2、参考xml文件： 更改 nameiso位置img位置
默认cpu mode 使用 ide 硬盘，后面可再安装virtio驱动
# more /opt/data/rock-feibiao/slse11-sp4/SLES-11-SP4-DVD-test.xml

3、启动、登录 虚拟机
virsh create /opt/data/rock-feibiao/slse11-sp4/SLES-11-SP4-DVD-test.xml
virsh vncdisplay rock_SLES-11-SP4-DVD-test-02
通过宿主机ip与端口 VNC登录虚拟机安装iso； 安装成功后 img文件及可用
二、OVA镜像转换
1. 解压file.ova文件：
# tar -xvf rsa-am-virtual-appliance-8.1.0.0.0.ova
2. 转换解压后的vmdk文件：
例：qemu-img convert -O qcow2 file.vmdk file.qcow2 -o compat=0.10
3、通过xml 启动img 若是无法启动使用ide 启动后安装virtio驱动
三、virtio驱动安装
解压initrd.img到指定目录mkdir temp
cd temp
gunzip -c /boot/initrd-xxx.img | cpio -i拷贝kernel module到initrd目录cp /lib/modules/xxx/kernel/driver/virtio/virtio.ko lib/
cp /lib/modules/xxx/kernel/driver/virtio/virtio_ring.ko lib/
cp /lib/modules/xxx/kernel/driver/virtio/virtio_pci.ko lib/
cp /lib/modules/xxx/kernel/driver/block/virtio_blk.ko lib修改脚本文件，自动加载脚本文件vi init
添加module
insmod lib/virtio.ko
insmod lib/virtio_ring.ko
insmod lib/virtio_pci.ko
insmode lib/virtio_blk.ko重新打包initrd 目录find . | cpio -c -o >../initrd-xxx.img
cd ..
gzip initrd-xxx.img
cp initird-xxx.img.gz /boot/initrd-xxx.img
不错
