Import OVA as Proxmox VM
OVA is a virtual appliance, ready to run on a hypervisor. With an OVA file, you can import the image into VirtualBox, VMWare, etc and all needed information is loaded from the file and you can start the VM. This works as long as your hypervisor is capable of reading an OVA file. Proxmox does not understand OVA, and you cannot use the image out of the box. Reading the provided VM definition is not possible. As an OVA file contains the VM disk, you can add the disk to a VM.
First, create a new virtual machine definition in Proxmox. You are going to import the disk image from the ova file, not the virtual machine definition. Therefore, you must first create a VM, this creates the necessary information in Proxmox, and then you are adding a disk to this VM.
The overall steps to add OVA image to Proxmox are :
- Create VM
- Delete associated disk
- Import OVA
- Assign OVA to VM
Create a new VM definition
In Proxmox, add a new VM. Note the VM ID. You need this later when importing the OVA disk.
Go through the wizard to create a normal new VM.
It seems that you have to add a disk. The disk will be deleted later, the configuration entered here is not important.
I’ll use a CPU with 2 cores.
I am using the VM for SAP HXE, therefore I am going to use a little bit more RAM: 24 GB RAM in total.
After going through the wizard, the VM definition is ready and you can let Proxmox create the VM.
The new VM will appear in the list of available VMs in your server. Note the ID: 101 and the available storage locations.
Delete associated disk
Open the VM configuration and got to Hardware. The disk you added in the wizard is listed. This disk must be removed.
Remove the disk
- Detach from VM
Select the disk and click on Detach. The disk state will change to unused.
- Remove disk from VM
After the disk is detached, remove it from the VM. This will delete the disk file.
The next step is to import the OVA disk and assign it to the VM. As Proxmox uses LVM for managing its storage, a provided tool must be used to import the disk to LVM and assign it to the VM. Copy ova file to Proxmox server. Unzip OVA file. OVA is a zip file, you can simply unzip it to see its content. It contains the VM definition (ovf) and the vm disk (vmdk).
tar -xzvf hxexsa.ova
To import the image, you need to specify the VM and location where the disk is imported to. This information is available in Proxmox. You can see a list when looking at the server at the left menu. I am going to use local-lvm and VM HXE with id 101.
qm importdisk 101 hxexsa-disk1.vmdk local-lvm -format qcow2
This starts the import process. Basically, the vmdk file is copied to the storage local-lvm. After the import finishes, the disk is listed in Proxmox.
Assign OVA to VM
The disk is now available in Proxmox and added to the VM, but not usable. The disk must be assigned to the VM. To do so, open the VM definition and go to hardware.
Click on Edit.
Here you can specify how the disk is accessed by the VM. SCSI should work. If you get errors, try IDE, etc. As result, the disk is added to VM and can be used.
Note: SAP HANA Express Edition
To get the disk shipped with SAP HXE working, I had to use SATA, not SCSI.
Add the disk as SATA.
Make sure the boot order is set to SATA.
Starting the server should now work and you should see the configuration dialog.

Thanks for your efforts.

When you say ” After the disk is detached, remove it from the VM. This will delete the disk file.: you don’t mean delete the disk file from the Proxmox “Local” do you, I have other systems using that file

the disk I refer to is the dummy one I had to create whenI started to create the new VM. That disk you should not be using anywhere else. It was only created by Proxmox VM wizard and is save to delete as it contains no data.

Thanks for this tutorial, I followed step by step the procedure but i can´t see de disk on the VM machine, in the Storage I can see the disk, but in the VM directly I can´t see, What should I check?

tar -xzvf hxexsa.ova
tar -xvf *.ova

OVA files aren’t GZIPed …. so, the command to extract the files, is:
tar -xvf my.ova
Without the “z” options

Thank you very much for the detailed description. I just wanted to mention, that after unzipping there also exists the ‘qm importovf’ command which works like a charm ..

If you start out in GUI stay in it and do not just copy the file to the server. Just copy it?????????????????? I got the files out just fine using 7zip but I can slam one computer against the other all day and it does not just copy. Proxmox does not have a GUI and the rest of us do not use command line. If you can not stay in GUI or explain all steps do not waste peoples time.

Proxmox is directed to people with a certain understanding of Linux. If you do not know how to copy files or how to issue commands at the OS level of your Proxmox server, maybe you can ask the people responsible for managing the server?
As an alternative, you can google how to copy files to Linux, e.g. WinSCP or Filezilla do the job.

I think it’s rather ridiculus to blame others for your inability to understand this really cool tutorial. I assume you found this tutorial by using a search engine. What’s keeping you from using it to find out how to copy files from one device to another?

Great guide! With this docu I came from rookie to rocky!! Nice job!
Myles Varns · November 16, 2020 at 20:12
Thank you for this! Been trying to find a good guide for how to do this.

Thank you. It sure helped this noob transfer a VirtualBox VM into Proxmox. Now I just need to figure out how to get more space to work with in my local-lvm.
It might be helpful to at least mention in your Import OVA section, the scp command for moving files between computers from the command line .
Also to identify what the command qm importdisk is looking for; ie, qm importdisk [OPTIONS] in addition to your specific example.

Hi! Proxmox CAN read OVF data directly when creating VM’s: it’s in their documentation.
Ie: qm importovf 999 WinDev1709Eval.ovf local-lvm
Ricardo · December 12, 2022 at 18:30
Very useful comment. I imported the ovf directly. It worked like a charm.
Aaron M. Galicia · October 11, 2021 at 16:44
Can’t thank you enough for this how to. I’ve used it now so many times that I have memorized the steps. Share more how to’s if you have’em..

Great work. you made it so easy for me. Thank you
Matthias · February 14, 2022 at 13:28
thanks for the great blog post. Everything works great and is very helpful for building playgrounds!

Thanks for your excellent write up, it has been really useful. When I extract my OVA file I end up with two vmdk disk files, dis1.vmdk and disck2.vmdk. Do I just add these to the VM as two separate scsi disks or do they need to be merged together first?

Thank you so much this helped me to import Kali linux fro virtualbox to proxmov
