Proxmox Cheat Sheet

Importing VMware Images

When exporting a VM from VMware, the image will likely get exported in one of two formats depending on how you exported it, OVF or OVA. Below are the steps for importing each into Proxmox. This was tested on version 5.3-8.

OVF

Transfer the .ovf and .vmdk to the host via SCP
Run qm importovf <vmid> <ovf file> <storage>, Ex: qm importovf 100 exported.ovf local-lvm

Note: if the .vmdk name differs from what’s stated in the manifest, you’ll need to rename it to match.
