Coverity notes that after we VIR_ALLOC_N(params, nparams) a failed call to virDomainGetCPUStats could result in nparams being set to -1. In that case, the subsequent virTypedParamsFree in cleanup will pass -1 which isn't good. Use the returned value as the number of stats to display in the loop as it will be the value reported from the hypervisor and may be less than nparams which is OK Signed-off-by: John Ferlan <jferlan@redhat.com>
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.
