...ng to do with collectd and how it runs programs. > Is it using LD_PRELOAD trickery, or replacing libc, or using seccomp? If I understand the question correctly - it's about how collectd loads its plugins? If so it uses: static int plugin_load_file(const char *file, _Bool global) { void (*reg_handle)(void); int flags = RTLD_NOW; if (global) flags |= RTLD_GLOBAL; void *dlh = *dlopen*(file, flags); //... reg_handle = (void (*)(void))*dlsym*(dlh, "module_register"); //... *(*reg_handle)();* } Does this give any clues?

Thank you, Rich, This was the issue indeed. export LIBGUESTFS_BACKEND=direct fixed it. The next step I tried was to integrate libguestfs in collectd virt plugin to collect this data automatically. In this case I'm having an unknown error in add_libvirt_dom() (same with add_domain) when it's invoking qemu-img to create overlay image. There is no difference between manual and service
