Sorry for my English.
Let me explain more detail what I would like to do.
Here is my setup.

1. One Linux box(D0) acts as dom0 with Xen4.0

2. One NetBSD 5.0.2(Du502) act as domU on D0
2.1 pkg_add aoe-vblade in Du502 and run as an AoE target[1,2], AoE is
similar to iSCSI
2.2 ex: vblade 1 1 xennet0 /TEST.img

3. Another Linux box(C1) issues read/write requests with dd
3.1. the /dev/etherd/e?.?[3] is AoE target block device which is
exported by Du502 and
       is showed under C1's /dev/etherd path
3.2 ex: modprobe aoe # ls /dev/etherd will find /dev/etherd/e1.1
           for i in {1..65535}; dd if=/dev/zero of=/dev/etherd/e1.1 bs=4K; done

4. wait for 20~40mins, D0 reboot without any warning.
  dd of=/dev/zero if=/dev/etherd/e1.1

And Yes, I tried
I'll try 
netbsd-current and Xen 3.4.2 later, but it would take a little time
And I try figure out how to remote debug netbsd kernel.(Is it possible?)
