Live migrate fails between non-dpdk and dpdk computes, because of 2 reasons:
1) dpdk compute is with huge pages non-dpdk is without
2) CPU is different between those 2 hosts
And once you delete dpdk comute - Fuel doesn't delete it from nova services and tries to migrate to non-existing compute.
If you remove it from nova services manually - this OSTF test passes.
