It's tested against both 6.11 (actually a slightly older branch in kvm.git) and the CentOS Stream 9 kernel. The CentOS Stream 9 kernel has the same SNP code as Linux 6.11. > while the current head of the amd fork on github works just > fine with 6.11. The current head of the AMD fork (https://github.com/AMDESE/qemu snp-latest) is not in line with the upstream kernel, for example: 66e7fbadfc8 i386/sev: Add KVM_EXIT_VMGEXIT handling for Page State Changes e9898385037 i386/sev: Add KVM_EXIT_VMGEXIT handling for Page State Changes (MSR-based) What problems are you seeing with Linux 6.11?
