<div dir="ltr"><div><div><div><div><div><div><div><div><div>Hi all,<br><br></div>Alternative to Martin's way:<br><br></div>Launch virt-manager on any Linux system (you can install virt-manager on CentOS)<br><br></div>In the virt-manager, create a new VM, customize the disk size, select the CentOS installer ISO image, and start performing the installation.<br>
<br></div>Note where you save the virtual disk for this VM.<br><br></div>Once installation finish, you will have a fully installed VM. You will use this virtual disk (usually qcow format) and upload it into Opennebula. This is your gold image.<br>
<br></div>After that, you need to configure your VM template in Opennebula. Here you need to define your NIC, memory, and point the disk information to your gold image that you have uploaded. You need to know if you are using persistence or non-persistence. Persistence will modify your gold image. Non-persistence will create a clone of your gold image, and changes will be written to that clone. That depends on your Opennebula storage architecture too.<br>

<br>
we create Images in the following way:<br>
<br>
1. create qcow2 disk:<br>
qemu-img create -f qcow2 base_centos.img 10G<br>
<br>
2. fetch installer image:<br>
wget <centos mirror>/centos6/6/os/x86_64/images/install.img<br>
<br>
3. install image:<br>
qemu-system-x86_46 -m 4096 -hda centos_base.img -cdrom install.img -boot d<br>
<br>
4. post install vm preparation:<br>
qemu-system-x86_46 -m 4096 -hda centos_base.img<br>
<br>
Within image:<br>
install acpid (needed to reboot/shutdown vm from open nebula management node)<br>
install one-context package<br>
<br>
5. upload image to opennebula<br>
attn: do not use sunstone for large images copied over network.<br>
copy image to open nebula management host (scp,..) and use local directory and image name.<br>
<br>
