Allow building other than Legacy-BIOS-only Proxmox images. Default is unchanged. To build UEFI proxmox image use: proxmox.qemuConf.bios = "ovmf"; (default is "seabios") To build image bootable using both "seabios" and "ovmf" use: partitionTableType = "hybrid"; BIOS can be switched in Proxmox between "seabios" and "ovmf" and VM still boots. (GRUB2-only, systemd-boot does not boot under "seabios") To build systemd-boot UEFI image: proxmox.qemuConf.bios = "ovmf"; boot.loader.systemd-boot.enable = true;
