Two pieces are required for SEV support - CPU and SEV firmware. Ryzen has the CPU support (as seen by the sev flag), but it does not have support for SEV firmware. Only EPYC parts have SEV firmware support.
Hi all,
I am following the steps described in https://libvirt.org/kbase/launch_security_sev.html to enable SEV in the kernel of my AMD Ryzen 5 PRO 2400G (with Ubuntu 18.10). However, for some reason when I run "kvm_amd.sev=1" in the terminal, this results in "kvm_amd: command not found". Does anyone know why I am getting this error?
Following the instructions in the README file, I run build.sh to create a new kernel. However I was unable to boot the new kernel (got a black screen) if "AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT" was enabled, so I decided to keep it disabled. Below you can find the config file of my kernel:
