Hi Yang,
Thanks for your quick reply. Sorry for the stupid question. The information I've got from intel or the help sample from https://www.qemu.org/docs/master/system/i386/sgx.html, We need to specify commands something like this to run SGX-EPC guest: qemu-system-x86-64 -m 2G -nographic -enable-kvm -cpu host,+sgx-provisionkey -object memory-backend-epc,id=mem1,size=512M,prealloc=on -M sgx-epc.0.memdev=mem1,sgx-epc.0.node=0 /tmp/volume-name.img Do you mean internally QEMU is converting -M sgx-epc to PC or Q35, can I choose which one to use? Thanks! Jinpu
