I started with guide from You dated 25 march 2012 to build Dom0 and
Xen 4.2, but with few modifications this time.
1) I used kernel 3.6-rc7 for Dom0 -->
2) I used Xen from http://xenbits.xen.org/hg/staging/xen-unstable.hg/
3) VGA patch from David's Gis rev 25240
4) I used pciback to hide my gtx560 from Dom0, and for a while i have
had second gfx - hd4850, but now i removed it and i have only gtx560,
still working

and finally I think I know what make that error 43 disappeared. At
first I did comment those lines in DomU config:

#pci_msitranslate = 1
#pci_power_mgmt = 1

When i had success with installation i start to remove comments and
the one which is nasty is pci_msitranslate. This make some other
problems, like not working USB ports, but ...

If any other information will be needed please let me know.

asus P8H67
asus GTX560 DCII top
4GB ram

ubuntu 12.04
Dom0 kernel 3.6-rc7
DomU windows 7 x64
nvidia drivers 275.33 - but possibly 275.50 also will work
