 ====== Testnode Access ======
 ===== Summary =====
-We have about 250 baremetal testnodes that get automatically reserved (locked) and unlocked by teuthology "workers."  Workers are daemons on the ''teuthology.front.sepia.ceph.com'' VM that are fed jobs via a beanstalk queue.  This page will cover setting up your workstation to lock and unlock testnodes as well as schedule teuthology suites.
+We have about 400 baremetal testnodes that get automatically reserved (locked) and unlocked by teuthology "workers" or "dispatchers."  Workers are daemons on the ''teuthology.front.sepia.ceph.com'' host that are fed jobs via a beanstalk queue.  This page will cover setting up your workstation to lock and unlock testnodes as well as schedule teuthology suites.
 Baremetal testnodes get OSes automatically "installed" using [[services:FOG]] when you lock them either via ''teuthology-lock'' or ''teuthology-suite''.
 ===== Teuthology Config =====
-Most developers schedule suites from the ''teuthology.front.sepia.ceph.com'' VM which automatically locks/unlocks machines.

 However, if you wish to run ''teuthology'' commands from your workstation, see https://docs.ceph.com/projects/teuthology/en/latest/INSTALL.html#installation-and-setup.

 ===== SSH Config =====
-Baremetal testnodes get reprovisioned with an already-configured OS image including a home dir for your user account.  Your ssh public key should be in your user's **and** the ''/home/ubuntu/.ssh/authorized_keys'' file on each testnode.  You should always SSH as your username.

-===== VPSes =====
-VPS (Virtual Private Servers) are ephemeral KVM virtual machines that are spun up on demand using, for example:
-\\ ''%%teuthology-lock --lock-many 1 --machine-type vps --os-type ubuntu --os-version 14.04%%''
-**More Information**
-  * http://docs.ceph.com/teuthology/docs/downburst_vms.html
-  * https://github.com/ceph/downburst
-Their hostnames are ''vpm{001..200}.front.sepia.ceph.com''.  A few [[hardware:mira]] are set aside as hypervisors.  See [[services:vpshosts]].
-You must create an RSA SSH keypair (named id_rsa/id_rsa.pub) to ssh to VPSes from the teuthology host.  We also recommend you have us add the public key to your pubkey file in the [[https://github.com/ceph/keys|keys repo]].
-//Note: You still need a keypair even when using SSH agent forwarding from your workstation.//
-The following ''~/.ssh/config'' is required for you to lock VPSes from the teuthology host.
