Installing Home Assistant OS using Proxmox 8

Has anyone attempted this on a Mac Mini? I have a macmini4,1 (mid 2010) that I am trying to set up with proxmox. I’m testing everything on an external hdd in a sata enclosure until I get the hang of it and to be sure I won’t screw up the internal ssd. I’ve tried multiple times to get the proxmox-ve installer to run on a usb stick but every time I try to boot, I just get a blank grey screen. As soon as I reboot and disconnect the usb stick everything boots up normally. I’ve tried using etcher, copying the iso using dd as well as a few other methods. They all result in the same blank grey screen. I even went as far as installing the rEFInd boot manager to see if that might help. It didn’t.

I ended up installing debian 10 and installing proxmox-ve on top of that. It was a messy process and a steep learning curve. I mostly got hung up on partitioning the hard drive for proxmox. I read some mixed suggestions like using one ext4 partition for data and a swap partition for swap. The other method was to create an LVM partition with a volume group named pve, ext4 logical partition for root (/), ext4 logical partition for data (/var/lib/vz), and a swap partition for swap.

Per Proxmox VE Administration Guide v6.2 section 2.3.1:
I ended up using the second method for partitioning. I created a 250GB LVM partition, created the pve virtual group, a root ext4 logical partition (32GB) mounted at /, a data ext4 logical partition (190GB) mounted at /var/lib/vz, and a swap logical partition (6GB) with no mount and left 32GB of free space for snapshot creation.

I’m not 100% sure if I did this the right way. I have proxmox-ve installed on a fresh install of debian 10 on the external hdd. But now I have an install of debian as well as proxmox-ve, which I’m not sure if that is the best way to do this.

If anyone has any tips or suggestions, I’m all ears. I am new to proxmox and would like to get this right before I move everything over to the mac mini ssd.
