Migration for the rackspace servers

[Kiril Nesenko]

Hello,

Please review the plan I've wrote for the migration.

MUST REQUIREMENTS
* Gluster data domain
* Export domain
* Open a ticket to rackspace regarding static MAC address mapping

STEPS
1. Install rackspace03.ovirt.org
2. Create gluster based DC and add gluser storage as data domain.
3. Add rackspace03.ovirt.org into the DC.
4. Create export domain.
5. Attach export domain into rackspace[01/02].ovirt.org.
6. Poweoff all VMs on rackspace[01/02].ovirt.org and export them.
7. Attach export domain to the gluster based dc
8. Import all vms
9. Poweroff vms and check their statuses/connectivity. In jenkins as well.
10. Add rackspace[01/02].ovirt.org to the gluster based dc
11. Do steps 5-10 for rackspace02


Will remove the local DCs a week after migration after we will be sure that everything is ok.
