5/2) Confirguration of the openQRM Cloud
Deprovisioning
Either the user itself can deprovision its own request via the external Cloud-portal or the
system-administrator of the Cloud can do this for all users from within the openQRM-server GUI. Deprovision a request will automatically free up all used resources. Image-snapshots will be removed too. Of course the user will get a mail including the deprovisioning details :
Create-vms-on-the-fly
Now lets submit another request to our Cloud but this time we are requesting 2 system in one request (the max-number of system per request can be set in the Cloud-config panel).
and approve the request via the openQRM-server UI -> Cloud plugin menu -> Cloud Reqeusts menu :
Since by default the Cloud is setup to automatically create new vms according the requests approving this reqest will deploy the one existing vm and create an addtional new one which will be deployed equally.
High-availability
As the last step in this howto we will show the high-availability features of the Cloud (and openQRM). First we need to enable and start the highavailability plugin via the openQRM plugin-manager
Then please create a new request similar to the first one. Request 1 system, Ubuntu kernel, ubuntu_iscsi image and the resource_type set to "VMware Server2 vm". Also mark the "highavailable" checkbox to enabled.
Here the details of the "highavailability" Cloud request from the system-administrators view :
Approve the request via the openQRM-sever GUI (if you did not set your Cloud to "auto-provision" via the Cloud-Config panel yet).
When the request is fully active on the first vm please go to the VMware Server2 manager in the openQRM GUI and "crash" the vm by clicking on "stop".
After a short time the second, still free vm will be deployed with the same appliacne according the request. openQRM automatically keeps your Cloud running.
hope you enjoyed this howto
