22.5. The ISO Uploader Tool
22.5.1. The ISO Uploader Tool
The ISO Uploader tool has been deprecated. Upload ISO images to the data domain with the Administration Portal or with the REST API. See Section 11.8.1, “Uploading Images to a Data Storage Domain” for details.
The ISO uploader is a tool for uploading ISO images to the ISO storage domain. It is installed as part of the Red Hat Virtualization Manager.
The ISO uploader command is
engine-iso-uploader. You must log in as the root user and provide the administration credentials for the Red Hat Virtualization environment to use this command. The
engine-iso-uploader -h command displays usage information, including a list of all valid options for the
22.5.2. Syntax for the engine-iso-uploader Command
The basic syntax for the ISO uploader command is:
# engine-iso-uploader options list # engine-iso-uploader options upload file file file
The ISO uploader command supports two actions -
listaction lists the ISO storage domains to which ISO files can be uploaded. The Red Hat Virtualization Manager creates this list on the machine on which the Manager is installed during the installation process.
uploadaction uploads a single ISO file or multiple ISO files separated by spaces to the specified ISO storage domain. NFS is used by default, but SSH is also available.Note
If you use SSH, you are prompted multiple times to enter the SSH user password. You can avoid these prompts by uploading the public SSH key to the iso domain server before uploading an ISO file, and then using the
--key-file=KEYFILEoption. One way to upload the public SSH key is to use the
ssh-copy-id -i ~/.ssh/mykey user@hostcommand.
You must specify one of the above actions when you use the ISO uploader command. Moreover, you must specify at least one local file to use the
There are several parameters to further refine the
- Displays the version of the ISO uploader command.
- Displays information on how to use the ISO uploader command.
- Sets PATH as the configuration file the command will to use. The default is /etc/ovirt-engine/isouploader.conf.
- Sets PATH as the specific file name the command will use to write log output. The default is /var/log/ovirt-engine/ovirt-iso-uploader/ovirt-iso-uploader_date.log.
- Sets PATH as the certificate for validating the engine. The default is /etc/pki/ovirt-engine/ca.pem.
- Specifies that no attempt will be made to verify the engine.
- Specifies that SSL will not be used to connect to the engine.
- Sets quiet mode, reducing console output to a minimum.
- Sets verbose mode, providing more console output.
- Force mode is necessary when the source file being uploaded has the same file name as an existing file in the destination ISO domain. This option forces the existing file to be overwritten.
Red Hat Virtualization Manager Options
- Specifies the user whose credentials will be used to execute the command. The USER is specified in the format username@domain. The user must exist in the specified domain and be known to the Red Hat Virtualization Manager.
Specifies the IP address or fully qualified domain name of the Red Hat Virtualization Manager from which the images will be uploaded. It is assumed that the image uploader is being run from the same machine on which the Red Hat Virtualization Manager is installed. The default value is
ISO Storage Domain Options
The following options specify the ISO domain to which the images will be uploaded. These options cannot be used together; you must used either the
-i option or the
- Sets the storage domain ISODOMAIN as the destination for uploads.
- Sets the NFS path NFSSERVER as the destination for uploads.
The ISO uploader uses NFS as default to upload files. These options specify SSH file transfer instead.
Sets USER as the SSH user name to use for the upload. The default is
- Sets PORT as the port to use when connecting to SSH.
Sets KEYFILE as the private key to use for SSH authentication. If you don’t set a key, you are prompted to enter the password of the user specified by
--ssh-user=USER. You must upload the public SSH key to the ISO domain server before uploading an ISO file. One way to do this is to use the
ssh-copy-id -i ~/.ssh/mykey user@hostcommand.
22.5.3. Specifying an NFS Server
Example 22.3. Uploading to an NFS Server
engine-iso-uploader --nfs-server=storage.demo.redhat.com:/iso/path upload RHEL6.0.iso
22.5.4. Basic ISO Uploader Usage
The example below demonstrates the ISO uploader and the list parameter. The first command lists the available ISO storage domains; the
admin@internal user is used because no user was specified in the command. The second command uploads an ISO file over NFS to the specified ISO domain.
Example 22.4. List Domains and Upload Image
engine-iso-uploader listPlease provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): ISO Storage Domain Name | Datacenter | ISO Domain Status ISODomain | Default | active
engine-iso-uploader --iso-domain=[ISODomain] upload [RHEL6.iso]Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort):
22.5.5. Uploading the VirtIO and guest tool image files to a storage domain
The ISO domain is a deprecated storage domain type. The ISO Uploader tool has been removed in Red Hat Virtualization 4.4. Red Hat recommends uploading ISO images to the data domain with the Administration Portal or with the REST API. See Section 11.8.1, “Uploading Images to a Data Storage Domain” for details.
virtio-win_version.iso image contains the following for Windows virtual machines to improve performance and usability:
- VirtIO drivers
- an installer for the guest agents
- an installer for the drivers
To install and upload the most recent version of
Install the image files on the Manager machine:
# dnf -y install virtio-win
After you install it on the Manager machine, the image file is
- Upload the image file to a data storage domain that was not created locally during installation. For more information, see Uploading Images to a Data Storage Domain in the Administration Guide.
- Attach the image file to virtual machines.
The virtual machines can now use the virtio drivers and agents.
For information on attaching the image files to a virtual machine, see Installing the Guest Agents, Tools, and Drivers on Windows in the Virtual Machine Management Guide.
