+## Convert to proper image format
+
+XCP-ng only supports the `vhd`, `vmdk` or `raw` image formats.  
+Use `qemu-img` to convert other formats into the desired format.  
+
+`vhd` and `vmdk` are both sparsely allocated and somewhat compressed, therefore being quicker to upload than `raw`.  
+
+To convert, use these options depending on the desired format:
+
+| QEMU format name | Disk format |
+| ---------------- | ----------- |
+| vpc              | vhd         |
+| vmdk             | vmdk        |
+| raw              | raw         |
+

+
+```
+qemu-img convert -f qcow2 -O vmdk <image>.qcow2 <image>.vmdk
+```

+
+## Import VM disk
+
+Use Xen Orchestra to import the disk.  
+The option can is found under `Import > Disk`  
+Select any storage repository on the server.

+
+## Create VM
+
+The imported disk is not directly usable. Instead, we create a new VM first.  
+Use whatever settings you want and create a new disk. **Make sure to choose a boot mode (BIOS/UEFI) that is compatible with the imported disk**  
+After creating the VM, go into its disk management and attach the imported disk.  
+The disk created with the VM can be deleted.  
+
+Finally, under the advanced tab, disable all other options besides booting from HDD and convert the VM into a template.
