Michal Privoznik 4b77b19406 virnettlscontext: Don't pass static key length to gnutls_dh_params_generate2()
As encryption norms get more strict it's easy to fall on the
insecure side. For instance, so far we are generating 2048 bits
long prime for Diffie-Hellman keys. Some systems consider this
not long enough. While we may just keep increasing the value
passed to the corresponding gnutls_* function, that is not well
maintainable. Instead, we may do what's recommended in the
gnutls_* manpage. From gnutls_dh_params_generate2(3):

  It is recommended not to set the number of bits directly, but
  use gnutls_sec_param_to_pk_bits() instead.

Looking into the gnutls_sec_param_to_pk_bits() then [1], 2048
bits corresponds to parameter MEDIUM.

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.
