We deprecated the command line option -old-param for the 10.0 release, which allows us to drop it in 10.2.

2025-07-12sev: Provide sev_features flags from IGVM VMSA to KVM_SEV_INIT2Roy Hopkins1-1/+4
IGVM files can contain an initial VMSA that should be applied to each vcpu as part of the initial guest state. The sev_features flags are provided as part of the VMSA structure. However, KVM only allows sev_features to be set during initialization and not as the guest is being prepared for launch. This patch queries KVM for the supported set of sev_features flags and processes the VP context entries in the IGVM file during kvm_init to determine any sev_features flags set in the IGVM file. These are then provided in the call to KVM_SEV_INIT2 to ensure the guest state matches that specified in the IGVM file. The igvm process() function is modified to allow a partial processing of the file during initialization, with only the IGVM_VHT_VP_CONTEXT fields being processed. This means the function is called twice, firstly to extract the sev_features then secondly to actually configure the guest.

2025-07-12backends/confidential-guest-support: Add set_guest_policy() functionRoy Hopkins1-0/+21
For confidential guests a policy can be provided that defines the security level, debug status, expected launch measurement and other parameters that define the configuration of the confidential platform. This commit adds a new function named set_guest_policy() that can be implemented by each confidential platform, such as AMD SEV to set the policy. This will allow configuration of the policy from a multi-platform resource such as an IGVM file without the IGVM processor requiring specific implementation details for each platform.

2025-07-12backends/igvm: Add IGVM loader and configurationRoy Hopkins1-0/+46
Adds an IGVM loader to QEMU which processes a given IGVM file and applies the directives within the file to the current guest configuration. The IGVM loader can be used to configure both confidential and non-confidential guests. For confidential guests, the ConfidentialGuestSupport object for the system is used to encrypt memory, apply the initial CPU state and perform other confidential guest operations. The loader is configured via a new IgvmCfg QOM object which allows the user to provide a path to the IGVM file to process.

2025-07-12backends/confidential-guest-support: Add functions to support IGVMRoy Hopkins1-0/+67
In preparation for supporting the processing of IGVM files to configure guests, this adds a set of functions to ConfidentialGuestSupport allowing configuration of secure virtual machines that can be implemented for each supported isolation platform type such as Intel TDX or AMD SEV-SNP. These functions will be called by IGVM processing code in subsequent patches. This commit provides a default implementation of the functions that either perform no action or generate an error when they are called. Targets that support ConfidentalGuestSupport should override these implementations. Signed-off-by: Roy Hopkins <roy.hopkins@randomman.co.uk> Acked-by: Michael S.
