For the s390x architecture the sysfs core_id alone is not unique. As a result it can happen that libvirt thinks there are less host CPUs available than really present. Currently, a logical CPU is equivalent to a core for s390x. We therefore produce a fake core id from the CPU number. Signed-off-by: Viktor Mihajlovski <mihajlov@linux.vnet.ibm.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.
