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.
