Public bug reported:

Description
===========
After launching a instance in AArch64 via Nova, running nova console log I can get some messy code information. Due to the console type is not correct.
==================
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.nova console-log <instanceid>

Expected result
===============
Get the console information

Actual result
=============
Messy Code or No information.

The default kernel command line is not properly in AArch64.
"console=tty0 console=ttyS0" is not supported in AArch64.

Environment
===========
1. Exact version of OpenStack you are running. See the following
  list for all releases: http://docs.openstack.org/releases/
   Nova development, commit code: 3e96b0fde010c3f800a539eec5376c3c379c8594

2. Which hypervisor did you use?
    Libvirt+KVM
    $ kvm --version
    QEMU emulator version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.1), Copyright (c) 2003-2008 Fabrice Bellard
    $ libvirtd --version
    libvirtd (libvirt) 1.3.1

2. Which storage type did you use?
   In the host file system,all in one physics machine.
