Hi,
We have problem of host CPU topology parsing on special
platforms (general platforms are fine). E.g.
On a AMD machine with 48 CPUs [1] (4 sockets, 6 cores indeed
[2]), VIR_NODEINFO_MAXCPUS [3] will always return 24 as the
total CPU number.
If it is returning 24, then surely we have the 'nodes' value
wrong in the virNodeInfo ? It sounds like it should have been
set to 2 (4 * 6 * 2 => 48)
[3] #define VIR_NODEINFO_MAXCPUS(nodeinfo)
((nodeinfo).nodes*(nodeinfo).sockets*(nodeinfo).cores*(nodeinfo).threads)
