On systems with many pcpus, the sexpr returned by xend can be quite large for dom0 when it is configured to have #vcpus = #pcpus (default). E.g. on a 80 pcpu system, where dom0 had 80 vcpus, the sexpr details for dom0 was 73817 bytes! Increase maximum buffer size to 256k.
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.
