lshw is running in Xen HVM DomU shows processors that do not exist

[xplicit]

Ubuntu server 12.04 AMD 64 beta with xen hypervisor installed from ubuntu packages. Guest is Ubuntu 12.04 desktop beta PVHVM DomU

In Xen config for virtual machine allocated only 3 vcpus, but lshw shows 6 phisical cpus and each has 32 logical cpus. The same issue in the HVM DomU. In PV DomU all look correct (for 1 VCPU lshw shows 1 Phisical CPU in virtual machine)
