A very simple skeleton for now that doesn't attempt to model any of
the agent configuration, but we can grow it later. Tested and works
on an EC2 instance with ECS.
All the new options in detail:
Enable docker in multi-user.target make container created with restart=always
to start. We still want socket activation as it decouples dependencies between
the existing of /var/run/docker.sock and the docker daemon. This means that
services can rely on the availability of this socket. Fixes#11478#21303
wantedBy = ["multi-user.target"];
This allows us to remove the postStart hack, as docker reports on its own when
it is ready.
Type=notify
The following will set unset some limits because overhead in kernel's ressource
accounting was observed. Note that these limit only apply to containerd.
Containers will have their own limit set.
LimitNPROC=infinity
LimitCORE=infinity
TasksMax=infinity
Upgrades may require schema migrations. This can delay the startup of dockerd.
TimeoutStartSec=0
Allows docker to create its own cgroup subhierarchy to apply ressource limits on
containers.
Delegate=true
When dockerd is killed, container should be not affected to allow
`live restore` to work.
KillMode=process
Overlayfs is quite a bit faster, e.g. with it the KDE 5 test takes ~7m
instead of ~30m on my laptop (which is still not great, since plain
9pfs is ~4m30s).
This works around:
machine: must succeed: nix-store -qR /run/current-system | grep nixos-
machine# error: changing ownership of path ‘/nix/store’: Invalid argument
Probably Nix shouldn't be anal about the ownership of the store unless
it's trying to build/write to the store.

(cherry picked from commit 57a0f140643cde409022e297ed05e05f8d34d778)
Previously we were using two or three (qemu_kvm, qemu_test, and
qemu_test with a different dbus when minimal.nix is included).
(cherry picked from commit 8bfa4ce82ea7d23a1d4c6073bcc044e6bf9c4dbe)
This option is defined in qemu-vm.nix, but that module is not always
imported.

(cherry picked from commit 03c55005dfd6fbcd5cf8e00128a3bb6336b3bc0f)
- most nixos user only require time synchronisation,
while ntpd implements a battery-included ntp server (1,215 LOCs of C-Code vs 64,302)
- timesyncd support ntp server per interface (if configured through dhcp for instance)
- timesyncd is already included in the systemd package, switching to it would
save a little disk space (1,5M)
A secret can be stored in a file. It is written at runtime in the
configuration file.
Note it is also possible to write them in the nix store for dev
purposes.
This commit introduces a nixos module for the Openstack Keystone
service. It also provides a optional bootstrap step that creates some
basic initial resources (tenants, endpoints,...).
The provided test starts Keystone by enabling bootstrapping and checks
if user creation works well.
This commit is based on initial works made by domenkozar.
Allows one or more directories to be mounted as a read-only file system.
This makes it convenient to run volatile containers that do not retain
application state.
Fix automatic mouse grabbing/releasing when running as a vmware guest.
1. The xf86inputvmmouse is not loaded by default. Add it.
2. InptutDevice sections for which specify a driver are ignored if
AutoAddDevices is enabled (which it is by default). See [1]. Instead use
an InputClass to load the vmmouse driver.

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.

The dnsmasq instance run by the xen-bridge.service errorenously
hands out 172.16.0.0 as the netmask over DHCP to the VMs. This
commit removes the option responsible for that from dnsmasq.conf,
so that the proper netmask is inferred by dnsmasq instead.

The calls to iptables in xen-bridge.service were missing the -w switch,
which caused them to fail if another script was calling iptables
at the same time. Fix it by adding the -w switch.

This adds the containers.<name>.enableTun option allowing containers to
access /dev/net/tun. This is required by openvpn, tinc, etc. in order to
work properly inside containers.
The new option builds on top of two generic options
containers.<name>.additionalCapabilities and
containers.<name>.allowedDevices which also can be used for example when
adding support for FUSE later down the road.
