New subject: [libvirt][PATCH v17 4/9] conf: expose SGX feature in domain capabilities
From: Haibin Huang <haibin.huang(a)intel.com>
Extend hypervisor capabilities to include sgx feature. When available,
the hypervisor supports launching an VM with SGX on Intel platfrom.
The SGX feature tag privides additional details like section size and
sgx1 or sgx2.

New subject: [libvirt][PATCH v17 6/9] qemu_cgroup: Allow SGX in devices controller
From: Michal Privoznik <mprivozn(a)redhat.com>
SGX memory backend needs to access /dev/sgx_vepc (which allows
userspace to allocate "raw" EPC without an associated enclave)
and /dev/sgx_provision (which allows creating provisioning
enclaves). Allow these two devices in CGroups if a domain is
configured so.

New subject: [libvirt][PATCH v17 8/9] security_dac: Set DAC label on SGX /dev nodes
From: Michal Privoznik <mprivozn(a)redhat.com>
As advertised in previous commits, QEMU needs to access
/dev/sgx_vepc and /dev/sgx_provision files when SGX memory
backend is configured. And if it weren't for QEMU's namespaces,
we wouldn't dare to relabel them, because they are system wide
files. But if namespaces are used, then we can set label on
domain's private copies, just like we do for /dev/sev.
