When setting the cpu tunables in virsh you are able to update only a subset of them. Virsh while doing the update updated all of the tunables, changed ones with new values and unchanged with old ones. This is unfortunate as it: a) might overwrite some other change by a race condition (unprobable) b) fails with range checking as some of the old values saved might be out of range This patch changes the update procedure so that only the changed value is updated on the host. This patch also fixes a very unprobable memory leak if the daemon would return a string tunable parameter, as the typed parameter array was not cleared.
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.
