That's why this is failing. You don't want to directly call openssl routines, because QEMU isn't necessarily linked against openssl. Have a look at the qcrypto* functions, which abstract away the differences between the various possible backends (nettle, gnutls, gcrypt) that QEMU might be using. thanks -- PMM
