https://bugzilla.redhat.com/show_bug.cgi?id=896092 mentions that qemu 1.4 and earlier only accept a simple start-stop range for the cpu=... argument of -numa. Libvirt would attempt to use -numa cpu=1,3 for a disjoint range, which did not work as intended. Upstream qemu will be adding a new syntax for disjoint cpu ranges in 1.5; but the design for that syntax is still under discussion at the time of this patch. So for libvirt 1.0.3, it is safest to just reject attempts to build an invalid qemu command line; in the future, we can add a capability bit and translate to the final accepted design for selecting a disjoint cpu range in numa. * src/qemu/qemu_command.c (qemuBuildNumaArgStr): Reject disjoint ranges.
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.
