Create and bind a queue dedicated to a host

We want to use a host "calcium" dedicated for several testruns.

For this we create a dedicated queue that we schedule our testruns in and bind that queue to the host "calcium".

Check host "calcium"

$ tapper host-list | grep calcium
        16 | calcium

So we know ID is 16.

What runs currently on "Calcium"

$ tapper host-list --name calcium
16 | calcium |      active |    testrun 49028 |                kvm | xen-3.4-testing-64 | xen-4.0-testing-64 |    xen-unstable-64 |      kernel_reboot |  Kernel-benchmarks |        kernel_osrc |        autoinstall

Create dedicated queue "slbench-perl"

Show existing viewes to get overview af existing queues:

$ tapper queue-list

Create new queue:

$ tapper queue-new --name slbench-perl --priority 300

Activate queue:

$ tapper queue-update --name slbench-perl --active

Bind queue to host

We want to connect the queue "slbench-perl" to the host "calcium".

Host binding is a property of the Host.

With this command we delete all existing bound queues (delqueue with empty list) and bind it to the wanted queue (delqueue happens before addqueue):

$ tapper host-update --id 16 --delboundqueue="" --addboundqueue slbench-perl
16 | calcium | active | in use | slbench-perl

If urgent we free host from currently running testrun

You can either wait until currently running workload finishes, or you can hardly finish it:

$ tapper host-update --id 16

Check that it is free:

$ tapper host-list --name calcium
16 | calcium |      active |             free | slbench-perl
