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
from the function signature and from its call site, and use config
for the TDX dynamic check.

This is a cleanup-only refactor with no intended functional change.

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.

Rob Bradford b3e8e2abc5 vmm, virtio-devices: Deny zero sector writes for autodetected raw images 
If the disk image was autodetected to raw (not specified with image_type
= 0) then in the virtio-block subsystem generate errors for writes to
block 0 (treat as if read-only). This gives an immediate error vs using
the image implementations in the block subsystem.

Rob Bradford 6f2357c14e vmm: Improve resiliency of image type handling 
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.

Saravanan D 924baa9c0f vmm: Forward device_id from NumaConfig to NumaNode 
The device_id field was added to both NumaConfig and NumaNode as part
of the Generic Initiator support, but create_numa_nodes() change
was missed when the commits were reorganized.

As a result, node.device_id is never propogated from the config to
the runtime node and the ACPI SRAT Type 5 (Generic Initiator Affinity)
entries were never emitted.

Add the missing propogation so that create_srat_table() can resolve
the device and emit the correct affinity structure

Fixes: #7717

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.

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.

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.

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.

Bo Chen 01d711e893 vmm: acpi: Explicitly write ITS identifier in IORT table 
The IORT specification (Revision E.b, Table 12) defines the ITS Group
Node structure with an ITS Identifiers array following the node header.
Although the IORT table is zero-initialized, this commit adds an
explicit write of the ITS identifier value (0) for clarity and spec
compliance.

This ITS identifier must match the `translation_id` field in the MADT
GIC ITS structure to ensure proper interrupt routing on ARM platforms.

Bo Chen c87ca39219 vmm: acpi: Generate IORT table according to spec revision E.b 
The current IORT table implementation is based on IORT Spec revision E.b
[1], as evidenced by:
* The PCI root complex node revision being set to `3`
* The code being updated in late 2021 [2] when revision E.b was the
  latest version

This patch ensures the IORT table is properly generated according to
this specification revision, fixing three issues:

1. The IORT table revision should be `3` rather than `2` (see Table 2 in
   the spec [1])

2. The GIC ITS group node revision should be `1` rather than `0`
   (see Table 12 in the spec [1])

3. The "Memory access properties" and "ATS Attribute" fields of the PCI
   root complex node  was set incorrectly - specifically the MAF (Memory
   Access Flags) including CPM and DACS bits (see Tables 14, 15, and 17
   in the spec [1])

Anatol Belski 3657db7843 vmm: mshv: Set PROCESSORS_PER_SOCKET property for CPU topologies 
On MSHV, exposing multithreaded CPU topologies requires setting the
PROCESSORS_PER_SOCKET partition property so that CPUID.0xB reports
correct logical processor counts and topology levels to the guest.

This property must be set after all vCPUs are configured, as the
hypervisor uses the complete vCPU layout to derive and report CPU
topology information.

Pascal Scholz a8d1411307 vmm: Write directly to member when creating new devices 
Virtio PCI devices are created in a set of nested functions. In each
of this functions a vector is created to add created devices to, only
to be appended to the vector of the higher nesting level. Those nested
vectors are unnecessary as we can directly write to the member of
`DeviceManager`.
