WIth ide instead ahci was with same results but about udev problem now 
seems I found the cause, seems the dom0 kernel.
With kernel 3.2.0-4-amd64 version 3.2.68-1+deb7u3 (from wheezy 
repository) don't works without udev file, with 3.16.0-0.bpo.4-amd64 
version 3.16.7-ckt11-1+deb8u3~bpo70+1 works.
Initially new pv drivers was with network not working with kernel <3.14 
but after seems was solved (I don't know the exactly commit) but seems 
that xen without udev file a newer kernel is still needed.
With 3.16 kernel I had other problems instead, for example with 
balloning (even if should not be used).
With second test with kernel 3.16 I tried to remove a workaround of 
balloning problem (dom0_mem=2G,max:3G in grub.cfg instead 
dom0_mem=2G,max:2G), I nomore saw kern.log spam but W7 domU crashed at boot.
Another strange things is even if with trace enabled don't show pv 
drivers debug lines with 3.16 kernel (on older tests with 3.16 did if I 
remember good)
In attachment the windows minidump.
I'm going crazy with these too many problems and haven't time to do all 
useful tests :(
Can you advice me about more useful tests for try to found/solve these 
problems?
Thanks for any reply and sorry for my bad english.
