* $out/bin/qemu-kvm should point to qemu-system-aarch64 on aarch64, libvirt expect it
* makeWrapper codes are separated as some architectures might require additional command flags (https://github.com/NixOS/nixpkgs/issues/31606#issuecomment-349675127)
* x86_64-on-i686 is not a native emulation and not supported by KVM, so it is removed from the list
This reverts commit 3a4e2376e4.
The reverted commit caused the fix for CVE-2016-9602 not to be applied
for qemu_test because it conflicts with the force-uid0-on-9p.patch.
So with the rebase of the patch on top of the changes of the
CVE-2016-9602.patch, both patches no longer conflict with each other.
I've tested this with the "misc" NixOS test and it succeeds.

patch yet.

The "misc" NixOS test is using Nix to query the store and it tries to
change the ownership of it while doing so.
This fails if Nix is not in a seccomp-sandboxed userid namespace, so
let's make chown() a no-op when applied to store paths.
Fixes the misc test (and possibly future tests) on older Nix versions.

Enables support for accessing files over HTTP:
qemu-system-x86_64 -drive media=cdrom,file=http://host/path.iso,readonly
Increases the closures size from 445 to 447 MiB.
The reason to patch QEMU is that with latest Nix, tests like "printing"
or "misc" fail because they expect the store paths to be owned by uid 0
and gid 0.
Starting with NixOS/nix@5e51ffb1c2, Nix
builds inside of a new user namespace. Unfortunately this also means
that bind-mounted store paths that are part of the derivation's inputs
are no longer owned by uid 0 and gid 0 but by uid 65534 and gid 65534.
This in turn causes things like sudo or cups to fail with errors about
insecure file permissions.
So in order to avoid that, let's make sure the VM always gets files
owned by uid 0 and gid 0 and does a no-op when doing a chmod on a store
path.
In addition, this adds a virtualisation.qemu.program option so that we
can make sure that we only use the patched version if we're *really*
running NixOS VM tests (that is, whenever we have imported
test-instrumentation.nix).
Tested against the "misc" and "printing" tests.
