Thank you guys for the quick answer, I'll try these tips, but a little
different, I can attach a VGA monitor to my NetBSD server and see the
debug screen if it occurs. 
But, first I'll try this configuration on my xl.conf:

## Global XL config file ##

# automatically balloon down dom0 when xen doesn't have enough free
# memory to create a domain
autoballoon=0

# full path of the lockfile used by xl during domain creation
lockfile="/var/lock/xl"

# default vif script 
#vifscript="vif-bridge"

# default output format used by "xl list -l"
output_format="json"

# first block device to be used for temporary VM disk mounts
#blkdev_start="xvda"

# default option to run hotplug scripts from xl
# if disabled the old behaviour will be used, and hotplug scripts will
be
# launched by udev.
#run_hotplug_scripts=1

And finally, if I wont have success, I'll try to enable de
hotplug_scripts.
