[libvirt][PATCH v11 0/4] Support query and use SGX
Posted by Lin Yang 5 days, 4 hours ago
This patch series provides support for enabling Intel's Software
Guard Extensions (SGX) feature in guest VM.

Giving the SGX support in QEMU had been merged. 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.

It depends on QEMU fixing[1], which will move cpu QOM object from
/machine/unattached/device[nn] to /machine/cpu[nn]. It requires libvirt
to change the default cpu QOM object location once QEMU patch gets
accepted, but it is out of this SGX patch scope.

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 does not support NUMA yet, since latest QEMU 6.2
release does not support NUMA.
It should contain

<devices>
    ...
    <memory model='sgx-epc'>
       <target>
           <size unit='KiB'>N</size>
       </target>
    </memory>
    ...
</devices>

Please note that SGX NUMA support will be implemented in future patches.
