By fixing the Dockerfile, we have now finalized the automated generation
of the Docker images for both architectures (amd64 and arm64).
Fixes#953
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
In order to support both amd64 and arm64, we rely on the TARGETARCH
variable that is passed from the docker buildx command, based on the
platform used to build the container image.
There is no way to rely directly on $(uname -m) to assign a variable
with the correct x86_64 or aarch64 values we're looking for. Both ENV
and ARG don't evaluate the command, which means they see it as a simple
string. Using RUN is the only way to evaluate a command.

Removing the ISA DMA configurations prevents the kernel from accessing
the port I/O 0x87, which was generating the following warning:
WARN:vmm/src/cpu.rs:378 -- Guest PIO read to unregistered address 0x87
Removing the TELCLOCK configuration prevents the kernel from accessing
the port I/O reserved for the memory manager, which was causing the
following warning:
WARN:vmm/src/memory_manager.rs:289 -- Unexpected offset for accessing
memory manager device: 15

This commit updates the AArch64 kernel config file and integration
test script to v5.8-rc4, and this update keeps the aarch64 guest
kernel in sync with the x86_64 one.

Updating the kernel from 5.6-rc4 to 5.8-rc4 allows us to remove the
dependency on both virtio-vsock and virtio-mem patches as they are now
part of the upstream kernel. We're still carrying virtio-iommu and
virtio-fs patches.

This commit adds supporting components and code for enabling the
AArch64 integration tests, including:
1. A Linux kernel config file to build kernel on AArch64 machines.
2. Refactoring the `run_integration_test.sh` to architecture
specific scripts for readability.

This update of Dockerfile will add support to the AArch64
integration tests and musl building, including:
1. Installation of the missing `setcap` binary on AArch64.
On AArch64, `setcap` binary should be installed via `libcap2-bin`.
This binary is needed in the integration test.
2. Related support for the cloud-hypervisor binary building by
musl toolchain.

The kernel version is updated from 5.5-rc1 to 5.6-rc4, including the
updated kernel config file.
The kernel branch contains virtio-fs, virtio-iommu and virtio-mem

virtio-vsock which will be merged upstream in the next release.

This option improves the security of the guest by randomising the start
address of the kernel in physical memory. We should turn this on so as
to ensure all our functionality such as memory hotplug and kernel
loading works as this is an option used widely in production.

In order to support nested virtualization and nested device passthrough
from our CI tests, we need some extra kernel configuration options to be
enabled.
CONFIG_KVM and CONFIG_VIRTUALIZATION for nested virtualization.
CONFIG_VFIO for nested device passthrough.
CONFIG_VIRTIO_IOMMU and CONFIG_ACPI_IORT for virtio-iommu support.
With all these new options applied, we can leverage virtio-iommu to
attach some VFIO devices to it and pass them through a second layer of
virtualization.

The last kernel we were using included some manual porting of the
virtio-pmem and virtio-fs patches. By moving to 5.3-rc3, we are now
closer to upstream since the virtio-pmem patches are part of the linux

virtio-fs maintainers, which works with the latest version of virtiofsd.
