How to upload qcow2 image into Proxmox?

Consider that after migrating from a standard Ubuntu installation to Proxmox for my home lab, we had one highly customized Ubuntu server that we wanted to integrate into Proxmox.

Follow the steps given below to do this:

• Make a simple virtual machine.
• General – We may call it whatever we like, but make a note of the VM ID because we’ll need it later.
• OS – On the right, select the VM OS choices and click the box. No media should be used.
• There might be no CD/DVD selection.
• System – Configure the VM’s OS Disks as needed. – Delete the default disk (by clicking the trashcan symbol).
• CPU with no hard drive configured – Configure VM OS Memory as needed – Configure VM OS Network as needed – Configure VM OS as needed

The final confibvguration in this case is as shown below:

Import the qcow2 image into the VM

This is the next step to Proxmox upload qcow2. We can use the qm command with the following basic syntax to import a qcow2 image into the virtual machine:

sudo qm importdisk VM ID qcow2 image storage name

The VM ID in this example is 102, the qcow2 image is /home/tom/Ubuntu.qcow2, and the storage name is Storage:

sudo qm importdisk 102 /home/tom/Ubuntu.qcow2 Storage
importing disk '/home/tom/Ubuntu.qcow2' to VM 102 …
Formatting '/Storage/images/102/vm-102-disk-0.raw', fmt=raw size=53687091200 preallocation=off
transferred 0.0 B of 50.0 GiB (0.00%)
transferred 512.0 MiB of 50.0 GiB (1.00%)
transferred 1.0 GiB of 50.0 GiB (2.00%)
transferred 50.0 GiB of 50.0 GiB (100.00%)
…
Successfully imported disk as 'unused0:Storage:102/vm-102-disk-0.raw'

Add the newly imported disk to the VM

To do this follow the steps given below as the next step for Proxmox upload qcow2:

• When we choose the VM and then Hardware, we find the newly inserted disk labeled as Unused Disk.
• Disk not in use under Hardware
  Select Add Add disk under Hardware by double-clicking the Unused Disk.
• The imported qcow2 image has now been imported and added to the VM as a disk (hard drive).

Change the boot order

We have to follow the steps given below to change the boot order:

• Select Boot Order from the Options menu.
• Under Options, check Enabled, and then click the hamburger icon (on the left) to adjust the boot order.
• Enable the hard disk and make it the first boot device.

After that, the qcow2 image has been imported, added to the VM, enabled, and set to be the first in the boot order.

The VM configuration is finished, and the VM may now be booted and utilized as needed.
