Where can I find a basic OVF template XML for importing VMs into Proxmox?

proxale · Mar 6, 2022

I am trying to migrate VMs from various existing platforms into Proxmox and they commonly allow exporting VMs either in OVF or OVA format. Unfortunately, there are various problems when trying to qm importovf because, depending on the platform, they have custom tags which seem to confuse the importer.

I literally have hundreds of VMs to migrate so manually importing their disk images and reconstructing their configuration by reading their individual XML is not a practical approach.

Due to this, I would want to write a script (for each platform) to read the key parameters from their configuration and inject into a template XML that the importer can handle. Does anybody have any idea if such a template exists or can Proxmox provide one?

note: even the xml from a virsh dumpxml of a standard Linux qemu/libvirt system cannot be parsed successfully by the importer.

can you post such an xml? we should be able to fix the bugs in such a case

XMl from standard KVM virsh dumpxml which produces the following errro with --dryrun

Code:

warning: unable to parse the VM name in this OVF manifest, generating a default value
{
   "disks" : [],
   "qm" : {
      "cores" : "",
      "memory" : ""
   }
}

Without --dryrun

Code:

warning: unable to parse the VM name in this OVF manifest, generating a default value
error during import, cleaning up created resources...
import failed - unable to parse value of 'cores' - type check ('integer') failed - got ''

XML from QNAP Virtualization Station also from virsh dumpxml
Generates similar error with --dryrun

As I had to get that task done quickly back then, I simply extended my script to generate the commands to create the VM and attach the disks.

Where can I find a basic OVF template XML for importing VMs into Proxmox?
