Paulo de Rezende Pinatti 657365e74f qemu: Check if AMD secure guest support is enabled
Implement secure guest check for AMD SEV (Secure Encrypted
Virtualization) in order to invalidate the qemu capabilities
cache in case the availability of the feature changed.

For AMD SEV the verification consists of:
 - checking if /sys/module/kvm_amd/parameters/sev contains the
   value '1': meaning SEV is enabled in the host kernel;
 - checking if /dev/sev exists

==============================
Libvirt API for virtualization
==============================

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.

For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.

Further information about the libvirt project can be found on the
website:
