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.
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.
Haibin Huang (4):
Define SGX capabilities structs
Get SGX capabilities form QMP
Convert QMP capabilities to domain capabilities
conf: expose SGX feature in domain capabilities
Lin Yang (2):
conf: Introduce SGX EPC element into device memory xml
qemu: Add command-line to generate SGX EPC memory backend
