Ubuntu 18.04.1 LTS ,aesm service didn't start

[yang__zhe]

I input the commands 'service aesmd start' and 'service --status-all',but asem service wasn't shown in the screen.

I ran the sample code[Sealed Data] in hardware mode,this is part of log printed in the screen:

Replay Protected DRM operation:
cannot create enclave, error code = 0x2006
cannot get platform service capability, error code = 0x4001
Initialization the DRM failed.

Hello.

Error code 0x2006 means SGX_ERROR_NO_DEVICE, which usually means the SGX driver hasn't been loaded. Did you install the SGX driver?  If it's installed and loaded you should see the /dev/isgx device.  The AESM will not start if the driver is not properly loaded.

You can build and install the driver from here:  https://github.com/intel/linux-sgx-driver

Or install the pre-built binary from here:  https://01.org/intel-software-guard-extensions/downloads

Hello,Scott.

Thank you very much for your help.But actually,I have already installed the driver.Is the reason that my computer's BIOS just has 'Software Control' option causing the problem?
