How to set up live-migration environment for Openstack with devstack
1.1) Install Ubuntu 12.04
[email protected]:~# cat /etc/*release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS"1.2) Prepare at least 2 hosts for live migration, the README is using 3 hosts, one nova-controller node and two nova-compute node
1.3) Suppose the host name for the README are as following:
1.3.1) nova-controller: devstack12/172.17.27.12
1.3.2) nova-compute1: devstack13/172.17.27.13
1.3.3) nova-compute2: devstack14/172.17.27.14
1.4) Make sure the three hosts are DNS resolvable by each other.
2) Install required packages for all hosts
2.1) apt-get update
2.2) apt-get install openssh-server
2.3) apt-get install -y git
2.4) apt-get install libxml2-dev -y libxslt-dev
2.5) apt-get install -y libmysqlclient-dev
3) Check out devstack with the version of Essex
2.1) cd /root
2.2) git clone -b "stable/essex" git://github.com/openstack-dev/devstack.git
2.3) A folder named as devstack will be created under /root/devstack
4) Configure localrc for both nova-controller and nova-compute node
4.1) nova-controller node
4.1.1) Logon to nova-controller node
4.1.2) cd /root/devstack
4.1.3) vim localrc
HOST_IP=172.17.27.12 (Your nova-controller IP) FLAT_INTERFACE=eth0 FIXED_RANGE=10.4.128.0/20 FIXED_NETWORK_SIZE=4096 FLOATING_RANGE=172.17.27.255/24 MULTI_HOST=1 LOGFILE=/opt/stack/logs/stack.sh.log MYSQL_PASS=supersecret RABBIT_PASS=supersecrete SERVICE_TOKEN=xyzpdqlazydog ADMIN_PASSWORD=nova MYSQL_PASSWORD=nova RABBIT_PASSWORD=nova SERVICE_PASSWORD=nova STATE_PATH=/export LOCK_PATH=/tmp
4.2) nova-compute node
4.2.1) Logon to nova-compute node (Need to configure for both of the two nova-compute nodes)
4.2.2) cd /root/devstack
4.2.3) vim localrc
HOST_IP=172.17.27.13 (Your nova-compute node IP) FLAT_INTERFACE=eth0 FIXED_RANGE=10.4.128.0/20 FIXED_NETWORK_SIZE=4096 FLOATING_RANGE=172.17.27.255/24 MULTI_HOST=1 LOGFILE=/opt/stack/logs/stack.sh.log ADMIN_PASSWORD=nova MYSQL_PASS=supersecret RABBIT_PASS=supersecrete MYSQL_PASSWORD=nova RABBIT_PASSWORD=nova SERVICE_PASSWORD=nova SERVICE_TOKEN=xyzpdqlazydog MYSQL_HOST=172.17.27.12 (Your nova-controller IP) RABBIT_HOST=172.17.27.12 GLANCE_HOSTPORT=172.17.27.12:9292 ENABLED_SERVICES=n-cpu,n-net,n-api,n-vol STATE_PATH=/export LOCK_PATH=/tmp
5) Install devstack on both nova-controller node and nova-compute node
6) Once install finished for both nova-controller node and nova-compute node, check if all nova service are happy face.

7) Configure NFS for live migration, you can create the NFS server anywhere as you like, for this README, we are creagting it on nova-controller node.
7.1) Condfigure nova-controller node as NFS server
7.1.1) apt-get install -y nfs-kernel-server
7.1.2) mkdir -p /export/instances/
7.1.3) chmod 777 -R /export/
7.1.4) mkdir -p /dev/md1
7.1.5) mkdir -p /raid1-1
7.1.6)
vim /etc/fstab
/dev/md1 /raid1-1 ext3 data=journal,relatime,nosuid,noexec,nodev 1 2
/raid1-1/instances /export/instances none bind 0 07.1.7) vim /etc/default/nfs-kernel-server
NEED_SVCGSSD=no # no is default
7.1.8) vim /etc/default/nfs-common
NEED_IDMAPD=yes
NEED_GSSD=no # no is default
7.1.9) vim /etc/idmapd.conf
[Mapping]
Nobody-User = nobody
Nobody-Group = nogroup
7.1.10) vim /etc/idmapd.conf -- only for JNDI
[Translation]
Method = nsswitch
7.1.11) sudo vim /etc/exports
/export 172.17.27.0/255.255.255.0(rw,sync,fsid=0,crossmnt,no_subtree_check)
/export/instances 172.17.27.0/255.255.255.0(rw,sync,no_subtree_check)
7.1.12) exportfs -ra
7.1.13) /etc/init.d/nfs-kernel-server restart
7.1.14) /etc/init.d/idmapd restart
7.2) Configure each nova-compute node as NFS client
7.2.1) apt-get install -y nfs-common
7.2.2) vim /etc/default/nfs-common
NEED_IDMAPD=yes
NEED_GSSD=no # no is default
7.2.3) modprobe nfs
7.2.4) mkdir -p /export/instances
7.2.5) vim /etc/fstab
172.17.27.12:/instances /export/instances nfs4 rw,hard,intr,rsize=32768,wsize=32768,nosuid,nodev 0 0
7.2.6) vim /etc/hosts.deny
rpcbind : ALL
7.2.7) vim /etc/hosts.allow
rpcbind : 172.17.27.12
7.2.8) mount -a -v
7.2.9) df -k
7.2.10) mount -t nfs4 172.17.27.12:/instances /export/instances
8) Config libvirt for nova-compute, this configure need to apply to all nova-compute nodes
8.1) vim /etc/libvirt/libvirtd.conf
8.1.1) Change "#listen_tls = 0" to "listen_tls = 0"
8.1.2) Change "#listen_tcp = 1" to "listen_tcp = 1"
8.1.3) Add "auth_tcp = "none""
8.2) vim /etc/init/libvirt-bin.conf
8.2.1) Change "env libvirtd_opts="-d"" to "env libvirtd_opts="-d -l""
8.3) vim /etc/default/libvirt-bin
8.3.1) Change "libvirtd_opts="-d"" to "libvirtd_opts="-d -l""
8.4) vim /etc/libvirt/qemu.conf
8.4.1) Change "#user = "root"" to "user = "root""
8.4.2) Change "#group = "root"" to "group = "root""
8.5) Restart libvirtd
stop libvirt-bin && start libvirt-bin
9) Update configuration for nova-compute nodes
9.1) copy /opt/stack/nova/etc/policy.json to /root
9.2) Add "state_path=/export" to /etc/nova/nova.conf
10) Restart nova-compute service for all nova-compute service.
10.1) ps -ef | gerp nova-compute
10.2) kill nova-compute
10.3) Start up nova-compute: (You can put "setsid" at the begining of the command to make it run as a daemon)
python /opt/stack/nova/bin/nova-compute --flagfile=/etc/nova/nova.conf11.1) Create a new instance
