In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

Xen is now maintained by yours truly, but libvirt currently doesn't work
as it's not built with the libxl driver.

Some use cases require libvirtd to be run as root on MacOS due to https://gitlab.com/qemu-project/qemu/-/issues/465
Running libvirtd as root uses runstatedir for the pid, but /run is not a valid or standard path on MacOS.
Libvirt checks this path + $(uname -r), which is the running Kernel.
current-system does not necessarily contain the running Kernel, but
booted-system does.
Broken in ad78ce7764, which ignored the
discussion in https://github.com/NixOS/nixpkgs/pull/286330. It is still
broken on non-NixOS Linux.
Fixes this error when trying to migrate a VM using Connectivity Mode
Tunneled:
Unable to migrate guest: Cannot find 'ssh' in path: No such file or directory
Fixes https://github.com/NixOS/nixpkgs/issues/221815
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.
Upstream documentation: https://www.libvirt.org/manpages/libvirt-guests.html#files
The `zfs` package is not supported on darwin at all, resulting in
an evaluation error.
This change conditionally removes the patch that tried to introduce
the dependency regardless of that fact in f00d562080,
https://github.com/NixOS/nixpkgs/pull/191552
