Manage OVA Virtual Servers

OnApp Cloud gives you high-end cloud management features for virtual servers that are built from OVAs including:   

This document provides the information on how you can manage the virtual servers built from OVA.

Edit OVA Virtual Server

You can edit resources for all VSs. Depending on the OS it is built on, some VSs can have their CPU and RAM resized without needing to be powered off ("resize without reboot"). If the OVA template allows resize without reboot, the resize should be completed automatically: you will be returned to the VS details screen and see a message indicating the resize was successful. If the template does not allow this, you will be asked to confirm that the VS will need rebooting so that the resize can take place.

To adjust VS resources:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the server you want to resize, to show its details screen.
3. Click the Actions button, point to Options, and select the Edit Virtual Server link.

4. Change CPU cores, CPU priority/units and RAM values.

5. Click the Save button.

Segregate OVA Virtual Server

If required, you can instruct OnApp to make sure a VS is never booted on the same compute resource as another specific VS. This may be important if, for example, you have two name servers or a load balanced web server, and you need to keep VSs on separate physical servers. 
To segregate one VS from another:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the virtual server you want to segregate.
3. On the screen that appears, click the Actions button, point to Performance, then click Segregate Virtual Server.
4. In the dialogue box that pops up, use the drop-down menu to choose a VS you want to keep away from.
5. Click the Segregate Virtual server button to finish.
   
   

Clone OVA Virtual Server

You can create a clone based on the same resources as the origin OVA virtual server. The cloned virtual server inherits resources from the origin as follows. 

To clone a virtual server, follow the next procedure:

1. Go to your Control Panel > Cloud > Virtual Servers.
2. Click a label of the virtual server that you want to clone.
3. Click Actions, point to Options, and then click Clone Virtual Server. 
4. In the pop-up box, click Clone Virtual Server to confirm the action. 

After you confirm the action, several transactions are run to complete the cloning process. You can check a status of each transaction in Activity Log of the virtual server. After the virtual server is cloned, it is powered off until you start it. 

Migrate OVA Virtual Server

OnApp allows migration of OVA virtual servers between compute resources that share common data stores (or data store zones). 

To migrate a virtual server:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the virtual server you want to migrate.
3. Click the Actions button, point to Options, and click the Migrate Virtual Server link.
4. In the window that appears, choose the target compute resource from the drop-down menu.
5. Click the Start Migration button.

After migration, the power status of your virtual server remains the same as before the migration.
OnApp administrators can control user access over virtual server migration. Using OnApp permissions, you can allow/forbid users to perform migration of all virtual servers, or their own servers only. This is handled via the Control Panel's Roles menu.

Delete OVA Virtual Server

Shut down the virtual server before destroying it. If you are deleting a VS that is running, the VS will be deleted after the time set in Timeout Before Shutting Down VSs configuration parameter.
To remove the virtual server from the cloud:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. On the screen that appears, you'll see the list of all virtual servers in the cloud. Click the label of the virtual server you want to delete.
3. On the virtual server's screen, click the Actions button, point to Options, then select Delete Virtual Server.
4. Confirm by clicking the Destroy button.

OVA Virtual Server Power Options

To manage a virtual server power options:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the required virtual server.
3. Click the Actions button on the VS's screen and point to Power expand the menu.
4. The Power menu enables you to perform the following power actions on VSs (the exact list shown depends on the VS status):

• • Reboot Virtual Server - powers off and then restarts the VS.

  • Reboot in Recovery- powers off and then restarts the VS in the recovery mode.

  • Suspend  - stops a VS, changes its status to suspended and disables all the other actions on VS, unless unsuspended.
  • Shut Down Virtual Server – pops up a dialogue box, where you can either Shut Down VS (terminates the VS gracefully), or Power Off VS (terminates the VS forcefully).

  • Startup Virtual Server - queues a start-up action for a VS that's currently powered off.

    When you start up a VS, it might be implicitly cold migrated if the current compute resource does not have sufficient resources. For more information, refer to Virtual Server Provisioning.

  • Startup on Recovery - starts the VS in recovery mode.
    
    

Change Owner of OVA Virtual Server

To change owner of OVA virtual server:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the required virtual server.
3. Click the Actions button on the VS's screen, point to Administration, and click the Change Owner link.
4. Choose a user to whom you want to pass ownership of the VS from the drop-down list.
5. Click the Change Owner button.
   
   

Set SSH Keys for OVA Virtual Server

To set SSH keys for OVA virtual server:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the required virtual server.
3. Click the Actions button, point to Administration, and click the Set SSH keys link. SSH keys of the administrator and a VS owner will be assigned to the VS. If a VS owner does not have any SSH keys, the system will only assign admin keys.
4. Click the Set SSH-keys button.
   
   

Reset Root Password for OVA Virtual Server

To reset root password of OVA virtual server:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Click the label of the required virtual server.
3. Click the Actions button, point to Administration, then click the Reset Root Password  link.
4. Move the Set password slider to the right to enter and confirm new password. Move the Encrypt password slider to the right to encrypt your password.
5. Click the Set Password button.
   
   

Set VIP Status for OVA Virtual Server

If a compute resource fails or reboots, the system migrates virtual servers to another compute resource, one VS at a time. The order VSs are migrated in is random. However, you can give a virtual server "VIP" status, and this will give that VS priority in the migration queue. 

To set or remove VIP status for a VS:

1. Go to your Control Panel > Cloud > Virtual Servers menu.
2. Use the icon in the VIP column next to a required virtual server to change switch on/off the VIP status.
