I met this problem too and this zombie domain could not be destroyed. 
I have opened a bug on this.

I saved a domain and ended up with a Zombie-migrating domain:

x235:~ # xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      250     1 r-----  5518.8
vm1                                1      127     1 ------  2564.9
Zombie-migrating-vm2               2        0     1 ---s-d  1292.4
vm3                                3      127     1 ------  1683.5
vm4                                4      127     1 ------  1783.8
vm5                                5      127     1 r-----  1615.0
vm2                                6      126     1 ------    10.9

At first I thought it was a temporary state, but after an hour or so, it 
is still there. I later restored it (vm2) successfully, but the zombie 
is still there.
