[libvirt][PATCH v7 0/5] Support query and use SGX

[Haibin Huang]

This patch series provides support for enabling Intel's Software Guard Extensions (SGX) feature in guest VM.
Giving the SGX support in QEMU be accepted and will be merged in two days Intel Software Guard Extensions
(Intel® SGX) is a set of instructions that increases the security of application code and data, giving them more
protection from disclosure or modification. Developers can partition sensitive information into enclaves, which
are areas of execution in memory with more security protection.
 
The typical flow looks below at very high level:
 
1. Calls virConnectGetDomainCapabilities API to domain capabilities that includes the following SGX information.
 
<feature>
...
  <sgx supported='yes'> 
    <epc_size unit=’KiB’>N</epc_size>
  </sgx>
</feature>
 
2. User requests to start a guest calling virCreateXML() with SGX requirement. 
It should contain
 
 <devices>
      ...
      <memory model='sgx-epc'>
        <target>
          <size unit='KiB'>N</size>
        </target>
      </memory>
      ...
  </devices>

Haibin Huang (2):
  Support to query SGX capability
  Add get domaincaps unit test

Lin Yang (3):
  conf: Introduce SGX EPC element into device memory xml
  qemu: Add command-line to generate SGX EPC memory backend
  Add unit tests for guest VM creation command with SGX EPC
