Xen issue

[philo_neo71]

Hi,
I ever wrote about XEN on a Post/Thread here (deamonforums), i restart to build a virtual machine with XEN.
I have read this url https://wiki.netbsd.org/tutorials/ho...os_using_xen3/

And of course, i change version of XEN, i try 45 and 46 version of xentools and xenkernel, but my computer reboot and ask the choise number of menu items.
I think that i forgot some item, and while computer reboot i've a black screen i don't know where is the issue.
Where is the log's files for XEN46?
I can do error of XEN's version !
My computer is a XEON with AMD distribution, like this, it's full 64bits.

Regards
Philippe
