We have a policy of avoiding enum types in structs in our public API, because it is possible for a client to choose compiler options that can change the in-memory ABI of that struct based on whether the enum value occupies an int or a minimal size. But we missed this for virDomainBlockJobInfo. We got lucky on little-endian machines - if the enum fits minimal size (a char), we still end up padding to the next long before the next field; but on big-endian, a client interpreting the enum as a char would always see 0 when the server supplies contents as an int. * include/libvirt/libvirt.h.in (virDomainBlockJobInfo): Enforce particular sizing.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
