The output from getty ("login:") does not always appear. This can be
observed interactively when booting the VM. (Mashing return will bring
it up.) Instead of checking for that string to ensure the VM has booted
instead check for a message from systemd to say it has started the SSH
daemon.
Fixes: #2799

It ensures all handlers for `ApiRequest` in `control_loop` are
consistent and minimum and should read better.
No functional changes.

It simplifies a bit the `Vmm::control_loop` and reads better to be
consistent with other `ApiRequest` handlers. Also, it removes the
repetitive `ApiError::VmAlreadyCreated` and makes `ApiError::VmCreate`
useful.

Simplified the build instruction on arm64.
And the binary built with default option can be used for both UEFI and
direct-kernel test.
Signed-off-by: Michael Zhao <michael.zhao@arm.com>
AArch64 tests were divided into 2 steps:
- Build and test with 'acpi' feature
- Build and test without 'acpi'
This can be optimized. We need only to build and test once with default
features ('acpi' is enabled).
On AArch64, ACPI only works with UEFI. If UEFI is not available, guest
kernel fall back to use FDT. Most AArch64 test cases boot from direct
kernel, the guest will keep using FDT even if ACPI is enabled. So
nothing is broken.

We have been building Cloud Hypervisor with command like:
`cargo build --no-default-features --features ...`.
After implementing ACPI, we donot have to use specify all features
explicitly. Default build command `cargo build` can work.
This commit fixed some build warnings with default build option and
changed github workflow correspondingly.

UEFI need to be loaded to a flash area at the beginning of guest memory
address space. To simulate the flash, we take a piece of RAM and hide
it to the guest. As this is a temporary solution, the hiden RAM for UEFI
should be as little as possible. The size was 64 MiB, that's too much,
4 MiB is enough.
The down side of such simulation is that there is a gap (4 MiB) between
the memory size in VMM's view and that in guest's view. This is to be
fixed by implementing a flash device in future.

Initialize MTRR defType register the same way the KVM code does - WB caching by default.
Tested with latest mshv code.
Without this patch, these lines are present in guest serial log:
[ 0.000032] x86/PAT: MTRRs disabled, skipping PAT initialization too.
[ 0.000036] CPU MTRRs all blank - virtualized system.
This indicates the guest is detecting the set MTRR.

The virtio_balloon test is a bit flaky since we can't really know how
much the balloon is gonna be deflated when the guest is under memory
pressure. That's why it's safer to simply check that the balloon is not
the initial size anymore.
One small detail, but we don't need to check for the balloon size to be
higher than 0 since the returned value is a u64.

To debug the FDT (Flattened Device Tree), we usually need to modify
source code to save the generted DTB data to disk, and use 'dtc' command
to decode the binary file into a text file to analyze.
It would be ideal if the FDT content can be seen in log.
This commit makes it real by:
- Introducing 'fdt' crate for parsing FDT.
- Printing the content of the FDT in tree view.
The parsing and printing only happen when Debug level logging enabled.

In order to allow a hotplugged vCPU to be assigned to the correct NUMA
node in the guest, the DSDT table must expose the _PXM method for each
vCPU. This method defines the proximity domain to which each vCPU should
be attached to.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
The _PXM method always return 0, which is wrong since the SRAT might
tell differently. The point of the _PXM method is to be evaluated by the
guest OS when some new memory slot is being plugged, but this will never
happen for Cloud Hypervisor since using NUMA nodes along with memory
hotplug only works for virtio-mem.
Memory hotplug through ACPI will only happen when there's only one NUMA
node exposed to the guest, which means the _PXM method won't be needed
at all.
