To enable booting virtual and smart servers from ISO in your cloud, you need to perform the following configurations:
Share the location where the ISOs are stored.
The default configuration is to upload ISOs on the Control Panel server. Then it is required to mount and share the location where the ISOs are stored at CP with all the compute resources. When the virtual servers are booted from the ISOs, the ISO is taken from the compute resource server. The location is preconfigured at on_app.yml config file which can be found in /onapp/interface/config/on_app.yml.
iso_path_on_cp- specifies the location where ISOs are stored on the Control Panel server. By default the location is /data. You can change it to any other suitable location. Make sure that this location is shared with the specified iso_path_on_hv location.
iso_path_on_hv- specifies the location where ISOs are located on the compute resource servers. By default the location is /data. You can change it to any other suitable location with the
onappowner and read/write access. Make sure that this location is mounted to the specified
CloudBoot compute resources mount the /data location automatically at boot to the /onapp/tools/recovery on HV. ISOs can be hosted on a dedicated server at any desired location with an arbitrary name if you wish. In this case it is necessary to mount the ISOs' location on this server to the Control Panel
iso_path_on_cp directory and all the compute resources'
iso_path_on_hv locations. This can be a backup server to avoid the excess usage of the Control Panel's space.
Enable ISO Permissions
If your cloud deployment is not a fresh installation, make sure to enable the following permissions for your Admin and other roles as appropriate:
- Any action on ISOs - the user can take any action on ISOs
- Create a new ISO - the user can create a new ISO
- Destroy any ISO - the user can delete any ISO (own, user, and public)
- Destroy own ISO - the user can only delete own ISO
- Destroy user ISO - the user can delete ISOs created by any user, but not public ISOs
- Make any ISO public - the user can make public any ISO available to all users
- Make own ISO public - the user can make public own ISOs only
- Make user ISO public - the user can make public ISOs created by any user
- Create and manage own ISOs - the user can create and edit/delete/view own ISOs
- Manage all ISOs - the user can manage own/user/public ISOs
- Create and manage user ISOs - the user can view/create/edit/delete ISOs created by any user
- See all ISOs - the user can view all ISOs in the cloud
- See own ISOs - the user can only view the ISOs created by themselves
- See all public ISOs - the user can view all public ISOs
- See user ISOs - the user can view the ISOs created by any user in the cloud
- Update any ISO - the user can edit any ISO in the cloud
- Update own ISO - the user can only edit own ISO
- Update user ISO - the user can edit the ISOs created by any user in the cloud
For more info refer to List of all OnApp Permissions.
Upload ISO(s) into the cloud.
Once you've configured the locations for storing ISOs, you can add a new ISO to the system. Follow this procedure:
- Go to your Control Panel and click the Templates menu from the left navigation pane.
- Select ISO list from the menu that expands.
- On the page that loads, click the Upload ISO button at the bottom of the screen.
- Choose the ISO to upload and fill its details:
- make public - move the slider to the right if you want to make the ISO publicly available
- label - choose a name for the ISO
- min memory size - specify the minimum required RAM for the ISO
- version - fill in the version of the ISO
- operating system - choose the operating system of the ISO
- operating system distro - fill in the operating system distribution of the ISO in free form
- virtualization - tick the required virtualization type(s): XEN, KVM or KVM+Virtio
- file - click Choose File to select the required ISO file from your file system. The yellow infobox will show the maximum file size for ISOs. The max upload size is pre-configured at Settings > Configuration (the Max upload size field).
- file url - select this tab if you want to upload the ISO from URL and specify the link from which the ISO will be uploaded.
- Click Save to upload the ISO.
After you upload an ISO to the cloud, it can be found at Templates > ISO List > My ISOs tab. The ISOs uploaded by your users are under the User ISOs tab.
Make ISO(s) public.
By default ISOs are available only to those users who uploaded them. These ISO images are available in the My ISOs tab. To make your ISO public and accessible for all users:
- Go to your Control Panel's Templates > ISO List menu.
- Click My ISOs tab.
- Click the Actions button next to the ISO you want to make public, then select Make public.
- Confirm the window that pops up.
When you make a user ISO public, it is moved to the System ISOs tab.
Make sure that you have enabled the Any power action on own virtual servers and Allow own virtual servers to boot from ISO permissions for the user to be able to boot servers from ISO.
Boot virtual or smart server from ISO.
Once you have shared the location where ISOs are stored and uploaded ISOs into the system, you can boot virtual or a smart servers from them using the server's power options menu. To boot a virtual/smart server from ISO:
- Go to your Control Panel's Virtual Servers/Smart Servers menu.
- Click the label of the required server.
- Click the Tools button on the server's screen to expand the Tools menu.
Select Boot from ISO. You can boot virtual/smart servers from your own ISOs or the ISOs that are uploaded and made publicly available by other users. If you boot a server from an ISO with the RAM requirement larger than the server's RAM, the transaction will fail.
