HOWTO install Ceph teuthology on OpenStack

Teuthology is used to run Ceph integration tests. It is installed from sources and will use newly created OpenStack instances as targets:

$ cat targets.yaml
  ubuntu@target1.novalocal: ssh-rsa AAAAB3NzaC1yc2...
  ubuntu@target2.novalocal: ssh-rsa AAAAB3NzaC1yc2...

They allow password free ubuntu ssh connection with full sudo privileges from the machine running teuthology. A Ubuntu precise 12.04.2 target must be configured with:

$ wget -q -O- ';a=blob_plain;f=keys/release.asc' | \
  sudo apt-key add -
$ echo '    ubuntu hard nofile 16384' > /etc/security/limits.d/ubuntu.conf

It can then be tried with a configuration file that does nothing but install Ceph and run the daemons.

$ cat noop.yaml
check-locks: false
- - mon.a
  - osd.0
- - osd.1
  - client.0
- install:
   project: ceph
   branch: stable
- ceph:

The output should look like this:

$ ./virtualenv/bin/teuthology targets.yaml noop.yaml
