Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

Add a masterKey and masterKeyLen to _qemuDomainObjPrivate to store a
random domain master key and its length in order to support the ability
to encrypt/decrypt sensitive data shared between libvirt and qemu. The
key will be base64 encoded and written to a file to be used by the
command line building code to share with qemu.
New API's from this patch:
qemuDomainGetMasterKeyFilePath:
Return a path to where the key is located
qemuDomainWriteMasterKeyFile: (private)
Open (create/trunc) the masterKey path and write the masterKey
qemuDomainMasterKeyReadFile:
Using the master key path, open/read the file, and store the
masterKey and masterKeyLen. Expected use only from qemuProcessReconnect
qemuDomainGenerateRandomKey: (private)
Generate a random key using available algorithms
The key is generated either from the gnutls_rnd function if it
exists or a less cryptographically strong mechanism using
virGenerateRandomBytes
qemuDomainMasterKeyRemove:
Remove traces of the master key, remove the *KeyFilePath
qemuDomainMasterKeyCreate:
Generate the domain master key and save the key in the location
returned by qemuDomainGetMasterKeyFilePath.
This API will first ensure the QEMU_CAPS_OBJECT_SECRET is set
in the capabilities. If not, then there's no need to generate
the secret or file.
The creation of the key will be attempted from qemuProcessPrepareHost
once the libDir directory structure exists.
The removal of the key will handled from qemuProcessStop just prior
to deleting the libDir tree.
Since the key will not be written out to the domain object XML file,
the qemuProcessReconnect will read the saved file and restore the
masterKey and masterKeyLen.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
