Hello, I have been testing Alma Linux Kitten and libvirt is not properly detecting SEV capabilities. Is Libvirt/QEMU compiled without SEV support ? $ dmesg | grep -i sev [ 1.821468] ccp 0000:45:00.1: sev enabled [ 53.414679] kvm_amd: SEV enabled (ASIDs 250 - 509) [ 53.414701] kvm_amd: SEV-ES enabled (ASIDs 1 - 249) [ 53.414720] kvm_amd: SEV-SNP disabled (ASIDs 1 - 249) $ virsh domcapabilities | grep -i sev <sev supported='no'/> $ virt-host-validate QEMU: Checking for hardware virtualization : PASS QEMU: Checking if device '/dev/kvm' exists : PASS QEMU: Checking if device '/dev/kvm' is accessible : PASS QEMU: Checking if device '/dev/vhost-net' exists : PASS QEMU: Checking if device '/dev/net/tun' exists : PASS QEMU: Checking for cgroup 'cpu' controller support : PASS QEMU: Checking for cgroup 'cpuacct' controller support : PASS QEMU: Checking for cgroup 'cpuset' controller support : PASS QEMU: Checking for cgroup 'memory' controller support : PASS QEMU: Checking for cgroup 'devices' controller support : PASS QEMU: Checking for cgroup 'blkio' controller support : PASS QEMU: Checking for device assignment IOMMU support : PASS QEMU: Checking if IOMMU is enabled by kernel : PASS QEMU: Checking for secure guest support : PASS QEMU: Checking for AMD Secure Encrypted Virtualization-Encrypted State (SEV-ES): PASS QEMU: Checking for AMD Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP): PASS
