[PATCH 00/12] Introduce SEV-SNP support

SEV-SNP support just landed in QEMU. Here is the first round of patches to incorporate support into libvirt. TODOs (aka problems of future me): - Teach tools/virt-qemu-sev-validate how to deal with SEV-SNP - Try to find a SEV-SNP machine a test these patches in real worl - Write a kbase article on attestation with SEV-SNP Michal Prívozník (12): qemu_monitor_json: Report error in error paths in SEV related code conf: Move some members of virDomainSEVDef into virDomainSEVCommonDef conf: Separate SEV formatting into a function Drop needless typecast to virDomainLaunchSecurity src: Convert some _virDomainSecDef::sectype checks to switch() qemu_monitor: Allow querying SEV-SNP state in 'query-sev' qemu: Report snp-policy in virDomainGetLaunchSecurityInfo() qemu_capabilities: Introduce QEMU_CAPS_SEV_SNP_GUEST conf: Introduce SEV-SNP support qemu: Build cmd line for SEV-SNP qemu: Allow setting launch security for SEV-SNP qemu_firmware: Pick the right firmware for SEV-SNP guests docs/formatdomain.rst | 108 ++++++++++++ include/libvirt/libvirt-domain.h | 10 ++ src/conf/domain_conf.c | 156 ++++++++++++++---- src/conf/domain_conf.h | 28 +++- src/conf/domain_validate.c | 44 +++++ src/conf/schemas/domaincommon.rng | 73 ++++++-- src/conf/virconftypes.h | 4 + src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_cgroup.c | 19 ++- src/qemu/qemu_command.c | 56 ++++++- src/qemu/qemu_driver.c | 60 +++++-- src/qemu/qemu_firmware.c | 20 ++- src/qemu/qemu_monitor.c | 7 +- src/qemu/qemu_monitor.h | 41 ++++- src/qemu/qemu_monitor_json.c | 67 ++++++-- src/qemu/qemu_monitor_json.h | 8 +- src/qemu/qemu_namespace.c | 3 +- src/qemu/qemu_process.c | 34 ++-- src/qemu/qemu_validate.c | 13 +- src/security/security_dac.c | 34 +++- .../caps_9.1.0_x86_64.xml | 1 + .../firmware/60-edk2-ovmf-x64-amdsev.json | 1 + tests/qemumonitorjsontest.c | 65 +++++++- ...launch-security-sev-snp.x86_64-latest.args | 35 ++++ .../launch-security-sev-snp.x86_64-latest.xml | 1 + .../launch-security-sev-snp.xml | 47 ++++++ tests/qemuxmlconftest.c | 2 + 28 files changed, 817 insertions(+), 127 deletions(-) create mode 100644 tests/qemuxmlconfdata/launch-security-sev-snp.x86_64-latest.args create mode 120000 tests/qemuxmlconfdata/launch-security-sev-snp.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-sev-snp.xml -- 2.44.2
