/etc/xen/domU is like:
kernel = "/boot/vmlinuz-2.6.11-xenU"
memory = 32
name = "DOMU"
disk = [ 'file:/data/rootfs,sda1,w' ]
root = "/dev/sda1 ro"
extra = "4"

3. xm list
[root@vt-yyou ~]# xm list
Name              Id  Mem(MB)  CPU VCPU(s)  State  Time(s)  Console
DOMU               3       32    0      1   -b---      1.7     9603
Domain-0           0      256    0      1   r----    104.1         

4. xm migrate -l 3 machine1
machine1 is another xen0 without the similar environment with local machine.

5. wait for a while no matter if migration is ok.

6. Ctrl+C to break the migration.

7. xm list
[root@vt-yyou ~]# xm list

DOMU               3       32    0      1   ---s-      4.3     9603
Domain-0           0      256    0      1   r----    139.5         

8. try to destroy domU. But domU couldn't be destroied. But after destroying, 
tts memory only contain 4MB.
[root@vt-yyou ~]# xm destroy 3
[root@vt-yyou ~]# xm list
Name              Id  Mem(MB)  CPU VCPU(s)  State  Time(s)  Console
DOMU               3        4    0      1   ---s-      4.3     9603
Domain-0           0      256    0      1   r----    142.1         

9. Try to create domU again. Of course it couldn't be create.
[root@vt-yyou ~]# xm create /etc/xen/domU 
Using config file "/etc/xen/domU".
Error: Error creating domain: vm name clash: DOMU

Current result:         
----------------
XenU couldn't be destroied, if migration failed.


Expected result:                
----------------
XenU could be destroied, not matter migration failed.
