Below is an example of a 4 node setup: A defines a NUMA node. describes the NUMA distance from the to the other NUMA nodes (the s). For example, in above XML description, the distance between NUMA node0 and NUMA node2 is 31. Valid distance value are '10 <=3D value <=3D 255'. A distance value of 10 represents the distance to the node itself. A distance value of 20 represents the default value for remote nodes but other values are possible depending on the physical topology of the system. When distances are not fully described, any missing sibling distance values will default to 10 for local nodes and 20 for remote nodes. Signed-off-by: Wim ten Have Reviewed-by: Daniel P. Berrange --- Changes on v1: - Add changes to docs/formatdomain.html.in describing schema update. Changes on v2: - Automatically apply distance symmetry maintaining cell <-> sibling. - Check for maximum '255' on numaDistanceValue. - Automatically complete empty distance ranges. - Check that sibling_id's are in range with cell identifiers. - Allow non-contiguous ranges, starting from any node id. - Respect parameters as ATTRIBUTE_NONNULL fix functions and callers. - Add and apply topology for LOCAL_DISTANCE=3D10 and REMOTE_DISTANCE=3D20. Changes on v3 - Add UNREACHABLE if one locality is unreachable from another. - Add code cleanup aligning function naming in a separated patch. - Add numa related driver code in a separated patch. - Remove from numaDistanceValue schema/basictypes.rng - Correct doc changes.

Signed-off-by: Wim ten Have --- Changes on v1: - Fix function calling (coding) standards. - Use virReportError(...) under all failing circumstances. - Reduce redundant (format->parse) code sorting bitmaps. - Avoid non GNU shorthand notations, difficult code practice. Changes on v2: - Have autonomous defaults applied from virDomainNumaGetNodeDistance. - Automatically make Xen driver simulate vnuma pnodes on non NUMA h/w. - Compute 'memory unit=3D' making it the sum of all node memory. Changes on v4: - Escape virDomainNumaGetNodeCount() if effective. --- src/libxl/libxl_conf.c | 121 +++++++++++++++++++++++++++++++++++++++++++= ++++ src/libxl/libxl_driver.c | 3 +- 2 files changed, 123 insertions(+), 1 deletion(-) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 34233a955..adac6c19c 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -374,6 +374,7 @@ libxlMakeDomBuildInfo(virDomainDefPtr def, def->features[VIR_DOMAIN_FEATURE_APIC] =3D=3D VIR_TRISTATE_SWITCH_ON);
