Libvirt native C API and daemons
f81ee7b549
Downstream CI recently encountered failures of libxlxml2domconfigtest when building libvirt packages against Xen 4.17 rc3 packages. The test fails on vnuma_hvm config, where suddently the actual json produced by libxl_domain_config_to_json() contains a 'pnode' entry in the 'vnuma_nodes' list, which is absent in the expected json. It appears the test has thus far passed by luck. E.g. I was able to make the test pass in the failing environment by changing the meson buildtype from debugoptimized to debug. When a VM config contains vnuma settings, libxlMakeVnumaList() checks if the number of requested vnuma nodes exceeds the number of physical nodes. The number of physical nodes is retrieved with libxl_get_physinfo(), which can return wildly different results in the context of unit tests. This change mocks libxl_get_physinfo() to return consistent results. All fields of the libxl_physinfo struct are set to 0 except nr_nodes, which is set to 6 to ensure the vnuma_hvm configuration is properly tested.

==============================
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:
