Small nit-pick - it'd be nice to split this patch in 2. One
patch doing virConnectBaselineCPU impl as $subject describes,
and one patch including CPU info  in the capabilities XML.

I think you should also fill in the sockets/cores/threads info
while you're doing this, since openstack is likely to start using
this data too in the near future. eg

  virNodeInfo nodeinfo;
  ...
  if (nodeGetInfo(&nodeinfo))
        goto error;
  ...
  cpu->sockets = nodeinfo.sockets;
  cpu->cores = nodeinfo.cores;
  cpu->threads = nodeinfo.threads;
