Uploading an ISO image

Before you can install an operating system inside a virtual machine, its installation image (the .iso file) must be uploaded to the server. This guide uploads an ISO image and confirms that it appears in the ISO image list when you create a virtual machine.

Before you begin

• The .iso file must be on the computer you are working from.
• You need an administrator sign-in for the VM2Cloud web interface.

Upload to local, not local-zfs

Installation images are stored on the local storage. The local-zfs storage holds virtual machine disks only — it does not offer an ISO Images option, and it will never appear in the ISO image list.

1. Sign in to the web interface

1. Open a web browser and go to https://<server IP address>:8006
2. Sign in as root with the administrator password.

2. Open the local storage

1. In the Server View panel on the left, click the arrow next to your server name to expand it.
2. Click local (your server name).

3. Open the ISO Images view

Click ISO Images in the menu next to the tree.

4. Upload the ISO file

1. Click Upload.

2. Click Select File, then choose the .iso file on your computer.
3. Check the File name shown. Leave Hash algorithm set to None.

4. Click Upload.

A task window opens and shows the progress. Wait until it reports TASK OK, then close it.

Note

Large images take several minutes. Do not close the browser tab while the upload is running.

5. Confirm the image is available

The file now appears in the ISO Images list with its date, format and size.

6. Check that it appears when creating a virtual machine

1. Click Create VM at the top right.
2. Go to the OS tab.
3. Leave Use CD/DVD disc image file (iso) selected.
4. In Storage, select local.
5. Open the ISO image list — your uploaded image is listed and can be selected.

You can now either continue and create the virtual machine, or click the close button to exit the wizard. To create a virtual machine, follow Creating a virtual machine.

Alternative — download an image directly to the server

If the image is available on a web address and the server has internet access, you can let the server fetch it instead of uploading from your computer:

1. Open local → ISO Images.
2. Click Download from URL.
3. Paste the address of the .iso file and click Query URL.
4. Check the file name and click Download.

If something goes wrong

What you see	What to do
There is no ISO Images option	You selected local-zfs. Select local instead.
The uploaded image is not in the ISO image list	Check that Storage on the OS tab is set to local.
The upload fails or stops	Check that the server has enough free space, and that the file really is an .iso file.
The upload is very slow	This depends on your network connection to the server. Consider using Download from URL instead.
