Rob Bradford 5b5e5cb999 vmm: cpu: Avoid potential infinite loop during core scheduling setup 
Avoid a potential infinite loop where if the leader fails to create a
cookie due to an unexpected error (not one of the SMT/no kernel support
errors) then the other vcpu threads will continue around their
spinloops.

This change also clarifies the state machine for the leader election
with an explicit enum.

Rob Bradford 3f800d2bb4 vmm: Add core scheduling support for vCPU threads 
Add a core_scheduling option to --cpus with three modes of operation.
This feature takes advantage of a kernel feature that restricts
scheduling of processes on the SMT threads on the same core. This is
useful for mitigating certain classes of side-channel attacks and has
better performance that disabling SMT on the CPU.

- vm (default): All vCPU threads share one core scheduling cookie.
  They may be co-scheduled on SMT siblings while host threads are
  excluded - this has minimal performance impact and can even
  potentially improve performance from co-location.
- vcpu: Each vCPU gets a unique cookie preventing any two vCPUs from
  sharing SMT siblings. This has the strongest isolation but at some
  compromise of performance.
- off: No core scheduling applied (old behaviour).

This isolation is done by the kernel maintaining a "cookie" - threads
with the same cookie can share the same core.

In vCPU mode each vCPU thread the cookie is created when the thread
starts and each gets a unique cookie. For VM mode the first vCPU thread
(the leader) will create the cookie. All other vCPU threads started (via
hotplug or during boot) will have that cookie shared to it.

EINVAL/ENODEV from prctl is silently ignored so this works transparently
on kernels older than 5.14 that lack PR_SCHED_CORE or when SMT disabled.

Full details of this kernel feature can be found at:
https://docs.kernel.org/admin-guide/hw-vuln/core-scheduling.html

This implementation was inspired by crosvm's implementation - in
particular the enable_core_scheduling() function.

This is challenging to test via integration testing but the logging of
the received cookie shows it working:

VM case:

cloud-hypervisor:   0.243102s: <vcpu1> INFO:vmm/src/cpu.rs:1247 -- vCPU 1: core scheduling cookie = 0x33e4c167
cloud-hypervisor:   0.243102s: <vcpu0> INFO:vmm/src/cpu.rs:1247 -- vCPU 0: core scheduling cookie = 0x33e4c167

vCPU case:

cloud-hypervisor:   0.089356s: <vcpu0> INFO:vmm/src/cpu.rs:1247 -- vCPU 0: core scheduling cookie = 0x13993ad6
cloud-hypervisor:   0.089380s: <vcpu1> INFO:vmm/src/cpu.rs:1247 -- vCPU 1: core scheduling cookie = 0xd48e86e

Pascal Scholz 15d1f1d7fd vmm: Refactor locking in AddressManager::move_bar 
The current implementation performs multiple operations on allocators in
a row, with the single goal of updating the allocator. For each of these
operations, the `Mutex` guarding the respective allocator is locked anew
which introduces room for race conditions.

Instead of locking the mutex multiple times, we should lock it once to
perform the whole move.

Muminul Islam c9cf3294ea vmm: remove duplicate vm config parameter 
Vm::create_device_manager accepted both config and _vm_config, but
both represented the same VM configuration source. Remove _vm_config

Demi Marie Obenour 989f3a3233 misc: generic vhost-user: reject virtio device IDs that cannot work 
Some virtio devices cannot be implemented via vhost-user because they
require tight integration with the VMM.  This includes the IOMMU and
watchdog devices.

An attempt to create a generic vhost-user device with one of these IDs
is always either a bug or human error.  To aid debugging, return a
helpful error message rather than silently continuing.

block 0 (treat as if read-only). This gives an immediate error vs using

Add an image_type to DiskConfig to specify the image type. If none is
specified autodetect the image type but disable potentially unsafe
behaviour in the QCOW2 backend by disabling the backing file support.

If the image type is autodetected then fix it in the config so that it
will be persistant across reboots and migrations/snapshot & restores.
This also handles the case where the image type was not specified as
part of the disk configuration.

Leander Kohler 30c86d5999 vmm: fix --net fd helptext for list syntax 
The --net help text documented fd as fd=<fd1,fd2...>, but
comma-separated FD lists in option values must be bracketed to avoid
top-level option splitting.

Update NetConfig::SYNTAX to use fd=<[fd1,fd2,...]>, matching parser
behavior and existing net parsing tests:
`cargo test -p vmm test_net_parsing`

Anatol Belski 49a30cbbaf block: raw: Implement disk preallocation for sparse=false 
When sparse=false is configured, preallocate the entire raw disk file
at startup using fallocate(). This provides space reservation and
reduces fragmentation.

Only applies to raw disks. QCOW2/VHD/VHDX formats manage their own
allocation.

Add sparse parameter to QcowFile constructors and propagate it from
device_manager through QcowDiskSync. This makes the sparse configuration
available throughout the QCOW2 implementation for controlling allocation
and deallocation behavior.

Anatol Belski 7dfcbff309 vmm: config: Add sparse flag to control disk space allocation 
Add sparse boolean configuration option to DiskConfig with a default
value of true to control disk space allocation behavior.

When sparse is true, the disk uses sparse allocation where deallocated
blocks are returned to the filesystem, and the DISCARD feature is
advertised to the guest.

When sparse is false, disk space is kept fully allocated and DISCARD
is not advertised.

WRITE_ZEROES is always advertised when the backend supports it,
regardless of the sparse setting.

Anatol Belski d5dad48618 block: Add sparse capability detection 
Add functions to probe whether a file or block device actually
supports PUNCH_HOLE and ZERO_RANGE operations at runtime. The
probe is performed at file open time by testing the operations
at EOF with a zero-length range, which is a safe no-op.

Muminul Islam 41b23229a5 vmm: refactor VM initialization into modular helper methods 
Decompose the monolithic `new_from_memory_manager` function into
smaller, focused helper methods to improve code readability,
maintainability, and testability.

Changes:
- Extract `should_force_iommu()` to determine IOMMU requirements for
  confidential computing (TDX/SEV-SNP)
- Extract `should_stop_on_boot()` to check debug pause configuration
- Extract `create_cpu_manager()` to encapsulate CPU manager creation
  and CPUID population
- Extract `init_tdx_if_enabled()` for TDX-specific VM initialization
- Extract `create_device_manager()` to encapsulate device manager setup
- Extract `hypervisor_specific_init()` to orchestrate initialization
  sequences for different hypervisors (KVM, MSHV, SEV-SNP)
- Extract `init_sev_snp()` for SEV-SNP confidential VM setup
- Extract `init_mshv()` for MSHV hypervisor initialization
- Extract `init_kvm()` for KVM hypervisor initialization
- Extract `create_fw_cfg_if_enabled()` for fw_cfg device creation

This refactoring replaces complex nested `cfg_if!` blocks with cleaner
conditional method calls, providing clear separation between hypervisor-
specific initialization paths while preserving existing functionality.

No functional changes intended.

Saravanan D 6d4827b5ff vmm: Add device_id field to NUMA configuration 
Add an optional device_id string field to NumaConfig for identifying
PCI devices associated with a NUMA node. This is used by the Generic
Initiator support to map devices to their proximity domain.

Update OpenAPI spec (cloud-hypervisor.yaml) to include the
new device_id field in the NumaConfig schema.

The device_id is optional and parsed from the --numa parameter:
  --numa "device_id=<device_id>,distances=[...],..."

The optional field is accepted but not used.

Saravanan D 231bbe2d5d vmm: Enforce guest_numa_id on NUMA nodes 
The documentation says guest_numa_id is required to be unique and
therefore the parser() giving default value for non-existing
guest_numa_id with .unwrap_or(0) is dangerous.

Return a validation error if guest_numa_id is not provided instead
of silently defaulting to 0.

Damian Barabonkov dde5f6ef38 vmm: Fix MMIO region removal during VFIO device hot-unplug 
When a VFIO device with multiple MMIO regions is hot-unplugged, each
region must be individually matched and removed from the DeviceManager's
mmio_regions list. Compare per-region rather than building an aggregate
across all regions, which would never match any individual entry.

Also remove the now-unused HashSet import.

Changyuan Lyu c2add07476 vmm: device_manager: avoid deep cloning device configs 
Replace `clone()` with `take()` when retrieving device configurations
from `DeviceManager.config`.

This avoids unnecessarily copying the device configuration lists (e.g.,
`disks`, `net`, `fs`) when they are being processed and subsequently
moved out of the configuration. This optimization improves performance
by reducing memory allocations and cloning overhead.

Set HV_PARTITION_CREATION_FLAG_SMT_ENABLED_GUEST when the guest

hypervisor to schedule guest VPs correctly on SMT-enabled hosts.

Without this flag, the hypervisor schedules guest VPs incorrectly,

Muminul Islam c9cd82b52b vmm: fix CVM boot failure on MSHV 
Recent changes related to arm64 support in MSHV exposed
inconsistencies in the VM initialization and CVM boot paths.
The VM creation flow currently diverges across multiple scenarios,
including regular MSHV, CVM, and arm64, with each path performing
guest initialization steps in a different order.
Certain platform-specific requirements further constrain the ordering
of operations, such as the timing of address space creation,
IGVM loading, interrupt controller setup, and payload loading. For
CVM case address-space creation must be done after IGVM loading, and
PSP measurement. For Regular and arm64 this memory initialization
must be done early. For MSHV, vm.init() and sev_snp.init() are called in
different order which is run time and build time conditionally checked.

Additionally, while the KVM initialization path differs slightly
from MSHV, it shares common logic that is currently split across
separate conditional and build-time code paths, contributing to
fragmentation of the overall flow.

This change restructures the VM creation and initialization sequence
to better align shared logic, enforce scenario-specific ordering
constraints, and ensure consistent and correct behavior across all
supported configurations. In doing so, it restores proper CVM boot
behavior and improves the maintainability of the initialization code.

Bo Chen 11edb28069 vmm: acpi: Clarify device ID partitioning in IORT table 
The IORT table's ID mapping uses a 256-ID offset per PCI segment to
ensure unique device IDs across all segments. This partitioning scheme
(output_base = 256 * segment_id) must match the device ID encoding used
in KVM MSI routing configuration [1].

This mapping assumes one bus per PCI segment, and supports up to 256 PCI
segments in the system.
