Reboots when booting /netbsd-XEN3_DOM0

[Adrien Fernandes <adrien_fernandes2%hotmail.com@localhost>]

I followed the wiki to make a DOM0 with NetBSD.
https://wiki.netbsd.org/ports/xen/howto/
And reading the wiki, I did the same as
https://wiki.netbsd.org/tutorials/how_to_set_up_a_xen_dom0/

- I downloaded netbsd-XEN3_DOM0.gz from ftp://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/yyyymmddhhmmZ/amd64/binary/kernel/netbsd-XEN3_DOM0.gz
- I put netbsd-XEN3_DOM0.gz in / where I "gunzip"ed it
- I installed sysutils/xenkernel46 and sysutils/xentools46
- I copied the xen* scripts from /usr/pkg/share/examples/rc.d to /etc/rc.d
- I enabled xend and xencommons in /etc/rc.conf
- I added an entry in /boot.cfg like this : menu=Xen:load /netbsd-XEN3_DOM0 console=pc;multiboot /usr/pkg/xen46-kernel/xen.gz dom0_mem=512M
- I restarted my computer choosing "Xen" to boot.

It boots then display some error messages and reboot.
I succeed to take a photo of my screen at that time. dmesg doesn't keep any trace of this error, just like if I never tried to boot my "Xen" entry
