This text is a copy of this post on Reddit, for archiving purposes:
- Download the KVM (qcow2) disk from here
- Copy it to your Proxmox server (you can do this with
scp) - Expand the xz file with
unxz
Create a new VM
- Enter the Proxmox GUI and Create a new VM
- Set up as you usually would, but remove all SCSI devices. Set BIOS to UEFI!
Import the disk
- SSH into your Proxmox instance
- Run
qm importdisk <VMID> /path/to/qcow2 <STORAGE> --format qcow2(replace<VMID>with the ID of your new VM (eg: 123), and<STORAGE>with the name of your chosen storage in Proxmox (eg:local-lvm).) - Run
qm set <VMID> --scsi0 <STORAGE>:<DISK-NAME>(you can find this info in the output of the previous command (eg: `local-lvm:vm-123-disk-0).) - In the Proxmox GUI, create a new EFI Disk for the VM, and disable “Pre-Enroll Keys”
Now you can boot the VM and see a brand new installation of Home Assistant OS!
