* iso: Minimal kernel for arm64
Create default arm64 config and disable stuff that we cannot use in
a VM.
This chagne was generated by:
1. Create defualt arm64 config
cd out/buildroot/output-aarch64/build/linux-6.6.95
make ARCH=arm64 defconfig
make ARCH=arm64 menuconfig
(exit saving changes)
2. Disable features that we don't need in the minikube VM:
- Platform suppport
- all platforms
- Device drivers
- Multimedia support
- Sound support
3. Updated our linux defconfig
cd out/buildroot/output-aarch64
make linux-update-defconfig
4. Normalize the config
make linux-menuconfig-aarch64
(exit saving changes)
With this config qemu, vfkit, and krunkit boot with --no-kubernetes, and
graceful shutdown works in vfkit and krunkit (using --restful-uri).
We cannot start kubernetes yet since some features are not available in
the default architecture config.
* iso: Add configs removed by defualt config
This restores the configs removed by updating from the default
architecture config. These configs are required for kubernetes support.
After adding the removed configs, run `make linux-menuconfig-aarch64` to
normalize the config and remove multimedia and sound card support again.
* iso: Unbreak go packages build
Adding go.work seems to break podman build. The workspace is needed only
for running the update commands so let's disable it when building the
iso.
We may need much bigger change to ensur that the workspace is used only
when running the update go commands, or remove it. This change fixes
only the iso build.

* iso: Update kernel to 6.6.95 for x86_64
Generated by running `make iso-menuconfig-x86_64` and updating kernel
version to longterm kernel 6.6.95 and kernel headers to 6.6.x, and then
running `make linux-menuconfig-x86_64` to update the linux config.
Additinally update hyperv-daemons package to use kernel 6.x.
* iso: Update kernel to 6.6.95 for aarch64

version to longterm kernel 6.6.95 and kernel headers to 6.6.x, and then
running `make linux-menuconfig-aarch64` to update the linux config.
* iso: Enable VirtIO GPU for krunkit driver
The krunkit driver exposes the host GPU via VirtIO GPU, enabling AI
workloads in the guest.

* iso: Extract buildroot target
Beofre we can build the iso, we need to clone and configure buildroot.
This is required to run iso-menuconfig-{arch}.
* iso: Extract iso-prepare-% target
This target prepare for building an iso or running menuconfig. With this
change we can run the {iso,linux}-menuconfig-{x86_64,aarch64} targets
without buidling the entire iso.
* iso: Fix linux-menuconfig-% target
Previouly it worked only after building the entire iso. Now we make this
target without building the iso or running iso-menuconfig.
On the first run this downloads and builds lot for packages required to
run the linux-menuconfig target, but it is much shorter than buidling
the entire iso.
* iso: Simplify linux-menuconfig-%
Preveviously we copied the defconfig manauly to the beoard config file.
This can be done using the special linux-update-defconfig target.
With this change we don't need to keep KERNEL_VERSION in the Makefile,
making future upgrade easier.
* iso: Update buildroot configuration for aarch64
Run `make iso-menuconfig-aarch64` without making any changes updates the
buildroot config. It seems that there were manual changes in the config
which are overwritten when running iso-menuconfig. Removing the manual
changes to make it easier to edit the configuration with kconfig.
* iso: Update buildroot configuration for x86_64
Same as the aarch64 change to make it easier to configure using kconfig.
* iso: Update linux configuration for aarch64
Same as iso-menuconfig-aarch64, run `make linux-menuconfig-aarch64` and
exit without any change to update the config. This seems to change the
order, removing manual changes from the config. This will make it easier
to configure using kconfig in the future.
* iso: Update linux configuration for x86_64
Same as the aarch64 changes to make it easier to configure using kconfig
in the future.
* iso: Disable all platform for aarch64
We run on qemu virt machine or apple virtualization so we don't need
support for all kinds of embeded Arm boards. This reduces the arm64 iso
size from 410 MiB to 392 MiB.

* iso: Disable grub timeout
This speeds up machine boot by 5 seconds. The timeout may be helpful for
debugging boot issues but we don't have a way to access the serial
console for debugging currently.
Testing shows about ~5 seconds speedup.
| driver | timeout | start time |
|------------|---------|------------|
| vfkit[1] | 5.0 | 24.01 |
| vfkit[1] | 0.0 | 19.90 |
| qemu | 5.0 | 29.46 |
| qemu | 0.0 | 24.28 |
| krunkit[2] | 5.0 | 25.14 |
| krunkit[2] | 0.0 | 20.51 |
[1] Tested with #20833, booting using iso instead of direct kernel
boot. Direct kernel boot is little bit faster (e.g. 18.x).
[2] Tested with #20826

* iso: Fix console for vfkit/krunkit
The serial console name depends on the driver. We had setting for qemu
that does not work for vfkit and krunkit, breaking boot from minikube
iso.
Fixed by using 2 console= options, one is known to work for qemu, and
one for vfkit and krunkit. With this we can use the same iso image with
qemu, vfkit, and krunkit.
This will allow simplifying vfkit driver. Previously we had to extract
the kernel and initrd and start it using the legacy --kernel,
--kernel-cmdline and --initrd options.
I tested this by building the iso with this fix and running with
--iso-url.
Example run with qemu:
% minikube start -p qemu --driver qemu --container-runtime containerd \
--iso-url file://$PWD/minikube-arm64.iso

* Fix KVM driver tests timeouts
Rewrite KVM driver waiting logic for domain start, getting ip address
and shutting domain down. Add more config/state outputs to aid future
debugging.
Bump go/libvirt to v1.11002.0 and set the minimum memory required for
running all tests to 3GB to avoid some really weird system behaviour.
* revert reduction of timelimit for TestCert tests run
* set memory and debug output in TestNoKubernetes tests
* extend kvm waitForStaticIP timeout
* add console log to debug output
