|If you still want create own Linux images, follow the steps below.
Watch how to VIDEO. It very similar process like for Windows. Just follow steps below.
For this you will need real Linux installation CD ISO distro.
We are using: ubuntu-16.04.2-desktop-amd64.iso. Be sure that distro name has not spaces in the filename! Any Linux Server installation has same procedure.
Create new image directory:
- Use WINSCP or FileZilla SFTP or SCP (port 22) to copy distro ISO image into the newly created directory, path: /opt/unetlab/addons/qemu/linux-ubuntu-desktop-16.04.02/
- From cli go to
- Rename this distro to cdrom.iso
mv ubuntu-16.04.2-desktop-amd64.iso cdrom.iso
- From EVE cli go to the created image directory
- Create new HDD virtioa.qcow2. Example below is HDD 30Gb. Size you can change per your needs.
/opt/qemu/bin/qemu-img create -f qcow2 virtioa.qcow2 30G
- Create new lab and add newly created linux-ubuntu-desktop-16.04.02 node
- Connect it to your home LAN cloud/internet, this need to get updates from internet
- Start node in lab and do install of your Linux, customize it as you like, as you have connected it to home LAN and internet this install will be like normal Linux installation.
- Remove cdrom.iso from /opt/unetlab/addons/qemu/linux-ubuntu-desktop-16.04.02/
rm -f cdrom.iso
IMPORTANT: Commit the installation to set it as the default image for further use in EVE-NG:
11. On the left side-bar within the lab in the EVE Web-UI choose “Lab Details” to get your lab’s UUID details: In this example: UUID: 3491e0a7-25f8-46e1-b697-ccb4fc4088a2
12. Find out the POD ID of your used and the Node ID of your newly installed node.
The POD number is assigned to your username, and can be found in the EVE GUI, Management/User Management. The Admin user uses POD number 0 by default.
The Node ID can be obtained by right clicking the node on the topology. In this Example it is 8
12. From the EVE CLI, locate the installed image and commit your changes to be used as default for further use in EVE-NG:
/opt/qemu/bin/qemu-img commit virtioa.qcow2
Advanced instructions on how to make your image smaller in size (sparsify&compress).
13. After you have done all the steps above and your default image is created, you can compress its HDD and make it smaller.
IMPORTANT: for compressing an image you must have sufficient free space on your EVE host, the free space must exceed the total space (30GByte in this example) of the HDD you plan to shrink. The space needed can vary but will be the total space of the disk to be shrunk plus the size of the final sparsified and compressed image. To be safe you should have double the size of the HDD you want to shrink as free space on your EVE host. In our example we needed 35Gbyte of free HDD space. Once this process is done, the temporary file(s) will be deleted and free space reclaimed.
14. From the CLI: go to your windows image directory:
and perform the sparsify command:
virt-sparsify --compress virtioa.qcow2 compressedvirtioa.qcow2
15. This will take some time and another compressed image will be created in the same image directory (win-7test)
16. Rename the compressed image name to virtioa.qcow2:
mv compressedvirtioa.qcow2 virtioa.qcow2
17. now you can test your new compressed image on a lab, just wipe the node and start it.
If the compressed node works fine, you can delete your original source image:
