KVM installation doesn't work

Installation
1

According to

I have to type in the following command:

virt-install --name hass --description "Home Assistant OS" --os-variant=generic --ram=2048 --vcpus=2 --disk <PATH TO QCOW2 FILE>,bus=sata --graphics none --boot uefi

So I typed in the following command:

[user@server tvshows]$ virt-install --name hass --description "Home Assistant OS" --os-variant=generic --ram=2048 --vcpus=2 --disk /mnt/sda/kvm/haos_ova-8.4.qcow2,bus=sata --graphics none --boot uefi

That gave me the following error:

ERROR    
An install method must be specified
(--location URL, --cdrom CD/ISO, --pxe, --import, --boot hd|cdrom|...)

Now what do I do?

Turns out, this installation requires uefi for some weird reason I don’t understand.
