Anyway, You was right, I badly tried emulate four (and then six) real socket CPU - while Win7 Pro support only two physical processors. Hopefully it is posible set right values for CPU sockets/cores/threads directly in virt-manager, under "Processor" -> "Topology" menu (or with "virsh edit VirtMachineName" - but I'm not familiar with all its command-line syntax).
