00:1d.* is the USB host controller. You're right.

You pointed me to the way how PCI devices are enumerated inside the 
domain.  I specify each pci function separately in config file, so I get 
different virtual devices in the HVM domain.
And by the now, I havn't noticed any problem with separated devices, 
which are the one multi-function pci device in real life. Perhaps, the 
moment of the badness doesn't come yet. :-) And it's not a SRIOV card.
I attached the screenshot, in which there are some separate pci devices 
in the HVM domain.

Well, I'm going to see what happens with shutdown case in more detail

Sergey.
