This adds a new ``parallelShutdown`` option that allows users to control
how many guests can be shut down concurrently. Allowing multiple virtual
machines to be shut down at the same time reduces the amount of time it
takes to reboot the host.

This fixes `lxd init`, which previously failed like this:
$ yes "" | lxd init
[...]
Error: Failed to create storage pool "default": Failed to run: losetup --find --nooverlap --direct-io=on --show /var/lib/lxd/disks/default.img: exec: "losetup": executable file not found in $PATH
Add a section on ordering option definitions.
Also mention `mkDefault` in the section on `mkOverride`.
Clarify the code a bit by renaming `defaultPriority` to
`defaultOverridePriority` and introducing `defaultOrderPriority`.
We don't need both wget and curl, so let's use only curl (which is
part of a minimal NixOS closure, unlike wget).
Logging to the console is helpful for debugging.
Instances without SSH keys configured will receive a 404 from the
metadata server when attempting to fetch an SSH key. This is not an
actual problem though, and shouldn't result in the service failing.
If the metadata server cannot be reached, the script will fail at an
earlier stage when attempting to get authentication data.
This also removes automatic enablement/mounting of instance store swap
devices and ext3 filesystems. This behaviour is strongly opinionated
and shouldn't be enabled by default.
The unionfs behaviour never took effect anyway, because the AMI
manifest path only exists for instance store-backed AMIs, which have
not been supported by nixpkgs since
84742e2293 (2019).
Previously we did socket-activation but this breaks the autostart
feature since upstream expects libvirtd to be started unconditionally on
boot.
Fixes#171623.
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;
Use hostPlatform if both the host and the containers nixpkgs supports
hostPlatform, otherwise fall back to localSystem. This preseves backwards
compatibility.
