So, a little background:<\/p>\n\n\n\n

  1. In Proxmox you have local mounted storage on each of your nodes.<\/li>
  2. You also have Thin-LVM volumes, which are an abstraction layer sitting on top of physical hardware; so like \/dev\/sdb isn’t the actual volume, it’s just the block storage for the thinly provisioned LVM volume.<\/li>
  3. You can put images there, but you can’t overwrite them to replace them if, for example, you have a raw disk image you’re trying to replace it with (because Proxmox doesn’t let you upload disk images sort-of directly) or let you refer to them directly when you’re creating a VM in the GUI.<\/li><\/ol>\n\n\n\n

    So now what? <\/p>\n\n\n\n

    1. Create a VM using the local storage, not your LVM-Thin directory.<\/li>
    2. Use SCP to upload the image to ‘\/mnt\/pve\/<node>\/images\/<number>\/<\/li>
    3. SSH into the server and go to the same directory; you’ll probably see two images, one named as ‘vm-<number>-disk-0.raw’ and one with your original name.
      1. If you made an EFI disk, expect there to be a vmdk, qcow2, or other image there. Don’t touch that one.<\/li><\/ol><\/li>
      2. Delete the original disk and rename the other to its name.<\/li>
      3. Use qm rescan to rescan the drive image, and you should be good.<\/li>
      4. Boot the new volume.<\/li><\/ol>\n\n\n\n

        In theory, anyway. You probably are going to get Not Found and Access Denied errors in the EFI loader when you try this. Here’s a list of the things I tried to get it working, and eventually did:<\/p>\n\n\n\n

        1. Turn off Secure Boot in the VM’s BIOS.<\/li>
        2. Add Boot Option to find the file itself.<\/li>
        3. Choose a SATA disk (not sure if this helped or not)<\/li>
        4. Delete, then readd, an EFI partition on the local storage with the .vmdk itself.<\/li>
        5. Try this a few times until some mysterious combination works.<\/li><\/ol>\n\n\n\n

          <\/p>\n\n\n\n

          Good luck…<\/p>\n\n\n\n
