This patch series provides support for enabling Intel's Software Guard Extensions (SGX) feature in guest VM.
 
Giving the SGX support in QEMU is still pending for reviewing, this patch series is not submmited for code
review, but only describe the SGX enabling solution design that contains changes to virConnectGetDomainCapabilities
API response and domain definition. All comments/suggestions would be highly appreciated.
 
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
 
<launchSecurity type='sgx'>
  <epc_size unit='KiB'>N</epc_size>
</launchSecurity>
