When virCPUx86UpdateLive checks whether a feature was added to a CPU model after the model was already released (vmx-* features in most Intel models), the following assert could be logged by glib: g_strv_contains: assertion 'strv != NULL' failed While most of our CPU models have a non-empty list of added feature, new models added in 2024 and versioned variants of older models have addedFeatures == NULL.
