Hello,
I am trying to build libvirt v10.5.0 to support SEV-SNP but when I run virsh domcapabilities I am getting <sev support=no>. If I install libvirt 8.0.0 using apt install libvirt-daemon-system qemu-kvm them sev shows as supported. Everything is enabled on the system about SEV, SEV-ES, SEV-SNP. Is there a specific build option to enable SEV?
