KVM image making and OVA mirroring conversion

First, the KVM installs the image through the ISO

1. Generate an empty IMG file

Qemu-img create-f qcow2/opt/data/rock-feibiao/slse11-sp4/sles-11-sp4-dvd-x86_64-gm-dvd1.img-opreallocation= Metadata 20G

2. Reference XML file: Change name ISO location IMG Location

The default CPU mode uses the IDE hard drive and the Virtio driver can be installed later

3. Start and log in the virtual machine

Virsh Create/opt/data/rock-feibiao/slse11-sp4/sles-11-sp4-dvd-test.xml

Virsh Vncdisplay rock_sles-11-sp4-dvd-test-02

Install ISO with host IP and port VNC login virtual machine, img file after successful installation and available

Second, OVA image conversion

1. Unzip the File.ova file:

# TAR-XVF Rsa-am-virtual-appliance-8.1.0.0.0.ova

2. Convert the extracted vmdk file:

Example: Qemu-img convert-o qcow2 file.vmdk file.qcow2-o compat=0.10

3. Start img via XML If you cannot start the installation of Virtio driver after using IDE boot

Three, Virtio Drive installation

Unzip initrd.img to the specified directory

mkdir Temp
CD Temp
Gunzip-c/boot/initrd-xxx.img | Cpio-i

Copy the kernel module to the INITRD directory

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

Modify the script file to automatically load the script file

VI Init
Add Module
Insmod Lib/virtio.ko
Insmod Lib/virtio_ring.ko
Insmod Lib/virtio_pci.ko
Insmode Lib/virtio_blk.ko

RePack INITRD Directory

Find. | Cpio-c-O-... /initrd-xxx.img
Cd..
Gzip initrd-xxx.img
CP initird-xxx.img.gz/boot/initrd-xxx.img
