We used the approach of cold-plugging network interface for pre-shimv2
support for docker.Since the hotplug approach was not required,
we never really got to implementing hotplug support for certain network
endpoints, ipvlan and macvlan being among them.
Since moving to shimv2 interface as the default for
runtime, we switched to hotplugging the network interface for supporting
docker and nerdctl. This was done for veth endpoints only.
Implement the hot-attach apis for ipvlan and macvlan as well to support
ipvlan and macvlan networks with docker and nerdctl.

ACPI PCI device hotplug on qemu virt is not supported. The only way to
hotplug pci device is pcie native way. Thus we need create pcie root
port as default.

2. virtio-mem dev;
3. add enough port for vhost user blk dev;

PR #6146 added the possibility to control QEMU with an extra HMP socket
as an aid for debugging. This is great for development or bug chasing
but this raises some concerns in production.
The HMP monitor allows to temper with the VM state in a variety of ways.
This could be intentionally or mistakenly used to inject subtle bugs in
the VM that would be extremely hard if not even impossible to debug. We
definitely don't want that to be enabled by default.
The feature is currently wired to the `enable_debug` setting in the
`[hypervisor.qemu]` section of the configuration file. This setting has
historically been used to control "debug output" and it is used as such
by some downstream users (e.g. Openshift). Forcing people to have the
extra HMP backdoor at the same time is abusive and dangerous.
A new `extra_monitor_socket` is added to `[hypervisor.qemu]` to give
fine control on whether the HMP socket is wanted or not. This setting
is still gated by `enable_debug = true` to make it clear it is for
debug only. The default is to not have the HMP socket though. This
isn't backward compatible with #6416 but it is for the sake of "better
safe than sorry".
An extra monitor socket makes the QEMU instance untrusted. A warning is
thus logged to the journal when one is requested.
While here, also allow the user to choose between HMP and QMP for the
extra monitor socket. Motivation is that QMP offers way more options to
control or introspect the VM than HMP does. Users can also ask for
pretty json formatting well suited for human reading. This will improve
the debugging experience.
This feature is only made visible in the base and GPU configurations
of QEMU for now.

by enabling IOMMU on the default PCI segment. For hotplug to work we need a
virtualized iommu and clh exposes one if there is some device or PCI segment
that requests it. I would have preferred to add a separate PCI segment for
hotplugging vfio devices but unfortunately kata assumes there is only one
segment all over the place. See create_pci_root_bus_path(),
split_vfio_pci_option() and grep for '0000'.
Enabling the IOMMU on the default PCI segment requires passing enabling IOMMU on
every device that is attached to it, which is why it is sprinkled all over the
place.
CLH does not support IOMMU for VirtioFs, so I've added a non IOMMU segment for
that device.

To enable this feature, build your rootfs using AGENT_POLICY=yes. The
default is AGENT_POLICY=no.
Building rootfs using AGENT_POLICY=yes has the following effects:
1. The kata-opa service gets included in the Guest image.
2. The agent gets built using AGENT_POLICY=yes.
After this patch, the shim calls SetPolicy if and only if a Policy
annotation is attached to the sandbox/pod. When creating a sandbox/pod
that doesn't have an attached Policy annotation:
1. If the agent was built using AGENT_POLICY=yes, the new sandbox uses
the default agent settings, that might include a default Policy too.
2. If the agent was built using AGENT_POLICY=no, the new sandbox is
executed the same way as before this patch.
Any SetPolicy calls from the shim to the agent fail if the agent was
built using AGENT_POLICY=no.
If the agent was built using AGENT_POLICY=yes:
1. The agent reads the contents of a default policy file during sandbox
start-up.
2. The agent then connects to the OPA service on localhost and sends
the default policy to OPA.
3. If the shim calls SetPolicy:
a. The agent checks if SetPolicy is allowed by the current
policy (the current policy is typically the default policy
mentioned above).
b. If SetPolicy is allowed, the agent deletes the current policy
from OPA and replaces it with the new policy it received from
the shim.
A typical new policy from the shim doesn't allow any future SetPolicy
calls.
4. For every agent rpc API call, the agent asks OPA if that call
should be allowed. OPA allows or not a call based on the current
policy, the name of the agent API, and the API call's inputs. The
agent rejects any calls that are rejected by OPA.
When building using AGENT_POLICY_DEBUG=yes, additional Policy logging
gets enabled in the agent. In particular, information about the inputs
for agent rpc API calls is logged in /tmp/policy.txt, on the Guest VM.
These inputs can be useful for investigating API calls that might have
been rejected by the Policy. Examples:
1. Load a failing policy file test1.rego on a different machine:
opa run --server --addr 127.0.0.1:8181 test1.rego
2. Collect the API inputs from Guest's /tmp/policy.txt and test on the
machine where the failing policy has been loaded:
curl -X POST http://localhost:8181/v1/data/agent_policy/CreateContainerRequest \
--data-binary @test1-inputs.json
