unable to execute QEMU command - SGX VM using libvirtd #768

Hello All,

Linux version 5.14.9-custom QEMU emulator version 6.2.0 (v6.2.0)

I am able to start a testvm using following commandline,

sudo qemu-system-x86_64 -nographic -enable-kvm -cpu host,+sgx -object memory-backend-epc,id=mem1,size=8M,prealloc=on -object mem0.memdev

But when I try the same with libvirt, I am getting this, error: internal error: unable to execute QEMU command 'qom-get': Property 'sgx-epc.unavailable-features' not found

testvm.xml content: `

test 3d5bba5b-0b5b-4b2b-a425-171fe9b31140 4194304 4194304 1 hvm /usr/share/OVMF/OVMF_CODE.fd /var/lib/libvirt/qemu/nvram/testvm_VARS.fd qemu64 destroy restart restart /usr/local/bin/qemu-system-x86_64
