I'm told SVSM has a dependency on host kernel KVM features not yet upstream, and I presume this means also needs further QEMU patches ? With regards, Daniel

Yes, you are right in that the host kernel does not yet support SVSM. However, I've tried to ensure that the IGVM implementation in QEMU will not require any further patches when SVSM support arrives in the kernel. This obviously cannot be guaranteed as it is not clear exactly what the SVSM support will look like, but as an example, take a look at https://github.com/coconut-svsm/linux/pull/6 which is a kernel branch that contains patches to support hosting COCONUT-SVSM which works with this QEMU IGVM patch series at V4. > > > With regards, > Daniel

Ah good, I was getting worried for a minute thinking QEMU might need to do extra KVM ioctl setup tasks to make it work. With regards, Daniel

Here is v4 of the set of patches to add support for IGVM files to QEMU. This is based on commit 1a2d52c7fc of qemu. This version addresses all of the review comments from v3 along with a couple of small bug fixes. This is a much smaller increment than in the previous version of the series [1]. Thanks once again to the reviewers that have been looking at this series. This v4 patch series is also available on github: [2] The previous version had a build issue when building without debug enabled. Patch 8/17 has been added to fix this and I've updated my own process to test both debug and release builds of QEMU. For testing IGVM support in QEMU you need to generate an IGVM file that is configured for the platform you want to launch. You can use the `buildigvm` test tool [3] to allow generation of IGVM files for all currently supported platforms. Patch 11/17 contains information on how to generate an IGVM file using this tool. Changes in v4: * Remove unused '#ifdef CONFIG_IGVM' sections * Add "'if': 'CONFIG_IGVM'" for IgvmCfgProperties in qom.json * Use error_fatal instead of error_abort in suggested locations * Prevent addition of bios code when an IGVM file is provided and pci_enabled is false * Add patch 6/17 to fix error handling from sev_encrypt_flash() * Revert unrequired changes to return values in sev/*_launch_update() functions * Add documentation to igvm.rst to describe how to use 'buildigvm' * Various convention and code style changes as suggested in reviews * Fix handling of sev_features for kernels that do not support KVM_SEV_INIT2 * Move igvm-cfg from MachineState to X86MachineState Patch summary: 1-12: Add support and documentation for processing IGVM files for SEV, SEV-ES, SEV-SNP and native platforms. 13-16: Processing of policy and SEV-SNP ID_BLOCK from IGVM file. 17: Add pre-processing of IGVM file to support synchronization of 'SEV_FEATURES' from IGVM VMSA to KVM.
