Description
===========
Using nova to create an instance in AArch64,and finally got AttributeError "'NoneType' object has no attribute 'parse_dom'" after "_get_guest_xml".
==================
1.Using devstack to deploy openstack. Using default local.conf.

2.Upload the aarch64 image with glance.
$ source ~/devstack/openrc admin admin
$ glance image-create --name image-arm64.img --disk-format qcow2 --container-format bare --visibility public --file images/image-arm64-wily.qcow2 --progress
$ glance image-create --name image-arm64.vmlinuz --disk-format aki --container-format aki --visibility public --file images/image-arm64-wily.vmlinuz --progress
$ glance image-create --name image-arm64.initrd --disk-format ari --container-format ari --visibility public --file images/image-arm64-wily.initrd --progress
$ IMAGE_UUID=$(glance image-list | grep image-arm64.img | awk '{ print $2 }')
$ IMAGE_KERNEL_UUID=$(glance image-list | grep image-arm64.vmlinuz | awk '{ print $2 }')
$ IMAGE_INITRD_UUID=$(glance image-list | grep image-arm64.initrd | awk '{ print $2 }')
$ glance image-update --kernel-id ${IMAGE_KERNEL_UUID} --ramdisk-id ${IMAGE_INITRD_UUID} ${IMAGE_UUID}
3.Set the scsi model:
$ glance image-update --property hw_disk_bus --property hw_scsi_model=virtio-scsi ${IMAGE_UUID}

4.nova add keypair
$ nova keypair-add default --pub-key ~/.ssh/id_rsa.pub

5.Launch the instance:
$ image=$(nova image-list | egrep "image-arm64.img"'[^-]' | awk '{ print $2 }')
$ nova boot --flavor m1.small--image ${image} --key-name default test-arm64

6.See the n-cpu log, we can get the error information.

Expected result
===============
Spawning guest successfully.

Actual result
=============
Got the error log information as below:
