https://bugzilla.redhat.com/show_bug.cgi?id=1356937 Add the definitions to allow for viewing/setting cgroup period and quota limits for IOThreads. This is similar to the work done for emulator quota and period by commit ids 'b65dafa' and 'e051c482'. Being able to view/set the IOThread specific values is related to more recent changes adding global period (commmit id '4d92d58f') and global quota (commit id '55ecdae') definitions and qemu support (commit id '4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow the IOThread value in the cgroup hierarchy was set "outside of libvirt" to a value that is incompatible with the global value. Allowing control over IOThread specific values provides the capability to alter the IOThread values as necessary.
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.
