It is recommended that you provide the description of the requested action (i.e. the text of one of the bullets listed above) as sub-task summary.
When a VM is closed, its corresponding issue is closed in JIRA.
Accessing QA Testbed virtual machine
Once a VM is created and assigned to the requestor, the VM is available via SSH. Developers are required to login by using SSH keys. In fact, login with passwords for SSH is disabled by default.
Virtual machines have ports 80 and 443 open.
As far as operating systems are concerned, currently Ubuntu server and CentOS are available.
Developers assigned to the requested machines have full root access to the machine, however, once the machine is broken, it will be simply rebuild from scratch and handed over again.
In case of problems with accessing the services on other ports (e.g. tomcat 8080) you can change service default port (see service administration guide). If you do not want to change service configuration, you can configure http proxy with e.g. nginx http and reverse proxy server (http://nginx.org/en, License BSD-like). If other port need to be open please request new sub-task issue with the request (with information port number and tcp/udp/both).

QA Testbed Resources and Limitations
The QA Testbed delivers virtual machines hosting Linux operating systems (Ubuntu, CentOS), dedicated to GN development teams as demo or testing instances. The QA Testbed hosts VMs assigned permanently to development teams as well as up to 50 Virtual Machines running in parallel and assigned to development teams on a resource-booking basis. Such limitations are due to hardware constraints and a number of assigned public IP addresses.
QA Testbed Procedures
The procedure for requesting virtual machine resources (with CentOS or Ubuntu OS) in the QA testbed is managed through Help Desk. The GÉANT QA testbed JIRA allows you to request the actions described below. The resource can be requested as a fixed VM (assigned permanently to a development team) or as a temporary VM (assigned for a particular time window). As far as the number of fixed VMs is concerned, initially development teams are assigned to the VMs according to the figures given at the time the requirements were specified. The QA testbed calendar shows the confirmed bookings of VMs that are already running, and can be used to check if resources might be available (approximate number of available resources = overall capacity of the QA testbed - resources assigned to already running VMs at a given date). However, the calendar does not guarantee that there are free resources, as there might be requests that are already being processed. The issue creation timestamp determines the order in which tickets are dealt with and resources assigned to VMs.

Requesting a VM snapshot
You can request a snapshot of a particular VM via the GÉANT QA testbed Help Desk by creating a sub-task for an issue that is related to the VM you want the snapshot of. The limitation is two snapshot per virtual machine. The procedure is as follows:
Browse the issues submitted to the GÉANT QA testbed project until you find an issue that corresponds to the VM you want a snapshot of.
...
Requesting the loading/reloading of the VM with a particular snapshot or new OS instance
You You can request a VM to be loaded from a particular snapshot via the GÉANT QA testbed Help Desk by creating a sub-task for an issue that is related to the VM you want the snapshot of. The procedure is as follows:
Browse the issues submitted to the GÉANT QA testbed project until you find an issue that corresponds to the VM you want to load from a snapshot.
...
Click Create to submit your request.
Please bear in mind that the operating system with all applications and other dependencies will be replaced with the snapshot you requested.
Changing the resource assignment for a particular VM
Once the resources are available, it is possible to increase the capacity of a virtual machine in terms of processor (GHz) and assigned RAM memory. This can be done where justified, i.e. when the history of VM utilization/load clearly shows that the VM resources are extensively used.
...
Click Create to submit your request.
The request will be analysed along with the load history of a particular VM, and confirmation will be sent whether the extension is reasonable and possible.
Requesting VM to be suspended/closed
If a permanently assigned VM is no longer going to be used, you should request the VM to be suspended to free up its resource for other requests. To do this:
Browse the issues submitted to the GÉANT QA testbed project until you find an issue that corresponds to the VM whose resources you want to extend.
