How to import a virtual machine (in OVA format) into Proxmox server

1.  Download the .ova file in the Proxmox server shell
2. Then do the following:

$ mkdir ova_import

$ cd ova_import

$ tar -xvf ../<filename>.ova

$ sudo qm importovf 101 ./<filename>.ovf <disk> --format qcow2

$ sudo qm importdisk 101 ./<filename>.vmdk <disk> --format qcow2

Then use the Proxmox GUI to attach the disk to the VM, configure Network and you're done!
