[AlmaLinux Users] Libvirt SEV support in Kitten

[Teodor Pripoae]

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'/>
