Subject: [PATCH] tests: Fix libxlxml2domconfigtest
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.
