hi! i’ve encountered with the same problem.both host and target are configured as well as it described in manuals: host – win7 x86, VS2010, visualddk 1.5, vmware 7.1. target – xp sp3 with installed virtualKD.
when i’m attaching via visualstudio’s kernel-mode connection transport, and “Loading kernel symbols” dialog appears – then error messages begins with the each pdb module currently processing – “Cannot load _path_to_pdb – unregistered class” (path to symbol store is set and it is correct), so what could happen?
