On Xen, libvirt runs in a VM (typically dom0) and does not have an accurate picture of numa and cpu topology of the underlying physical machine using the "usual" mechanisms. numa info and cpu toplogy are retrieved from libxl and used to populate the libvirt conterparts. Commit 7b79ee2f78b introduced support for reporting die_id in capabilities, but did not account for special handling of numa and cpu topology in libxl. Currently, Xen does not report die_id in the libxl_cputopology structure. In the meantime, set die_id to 0, which was suggested by the Xen developers and is slightly better than random garbage such as <cpu id='1' socket_id='0' die_id='-1073069552' core_id='0' siblings='0-1'/> Signed-off-by: Jim Fehlig <jfehlig@suse.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com>
Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
