18.6. The ISO Uploader Tool
18.6.1. The ISO Uploader Tool
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 engine-iso-uploader command.
18.6.2. Syntax for the engine-iso-uploader Command
The basic syntax for the ISO uploader command is:
engine-iso-uploader[options]listengine-iso-uploader[options]upload[file].[file]...[file]
The ISO uploader command supports two actions -
list, and upload.
- The
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. - The
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.
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
upload action.
There are several parameters to further refine the
engine-iso-uploader command.
General Options
--version- Displays the version of the ISO uploader command.
-h,--help- Displays information on how to use the ISO uploader command.
--conf-file=[PATH]- Sets [PATH] as the configuration file the command will to use. The default is
/etc/ovirt-engine/isouploader.conf. --log-file=[PATH]- 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. --cert-file=[PATH]- Sets [PATH] as the certificate for validating the engine. The default is
/etc/pki/ovirt-engine/ca.pem. --insecure- Specifies that no attempt will be made to verify the engine.
--nossl- Specifies that SSL will not be used to connect to the engine.
--quiet- Sets quiet mode, reducing console output to a minimum.
-v,--verbose- Sets verbose mode, providing more console output.
-f,--force- 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
-u [USER],--user=[USER]- 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.
-r [FQDN],--engine=[FQDN]- 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
localhost:443.
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 -n option.
-i,--iso-domain=[ISODOMAIN]- Sets the storage domain [ISODOMAIN] as the destination for uploads.
-n,--nfs-server=[NFSSERVER]- Sets the NFS path [NFSSERVER] as the destination for uploads.
Connection Options
The ISO uploader uses NFS as default to upload files. These options specify SSH file transfer instead.
--ssh-user=[USER]- Sets [USER] as the SSH user name to use for the upload. The default is
root. --ssh-port=[PORT]- Sets [PORT] as the port to use when connecting to SSH.
-k [KEYFILE],--key-file=[KEYFILE]- Sets [KEYFILE] as the public key to use for SSH authentication. You will be prompted to enter the password of the user specified with
--ssh-user=[USER]if no key is set.
18.6.3. Specifying an NFS Server
Example 18.5. Uploading to an NFS Server
# engine-iso-uploader --nfs-server=storage.demo.redhat.com:/iso/path upload RHEL6.0.iso18.6.4. 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 18.6. List Domains and Upload Image
# engine-iso-uploader list
Please 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):18.6.5. Uploading the VirtIO and Guest Tool Image Files to an ISO Storage Domain
The example below demonstrates the command to upload the
virtio-win.iso, virtio-win_x86.vfd, virtio-win_amd64.vfd, and rhev-tools-setup.iso image files to the ISODomain.
Example 18.7. Uploading the VirtIO and Guest Tool Image Files
# engine-iso-uploader --iso-domain=[ISODomain] upload /usr/share/virtio-win/virtio-win.iso /usr/share/virtio-win/virtio-win_x86.vfd /usr/share/virtio-win/virtio-win_amd64.vfd /usr/share/rhev-guest-tools-iso/rhev-tools-setup.iso18.6.6. VirtIO and Guest Tool Image Files
The virtio-win ISO and Virtual Floppy Drive (VFD) images, which contain the VirtIO drivers for Windows virtual machines, and the rhev-tools-setup ISO, which contains the Red Hat Virtualization Guest Tools for Windows virtual machines, are copied to an ISO storage domain upon installation and configuration of the domain.
These image files provide software that can be installed on virtual machines to improve performance and usability. The most recent virtio-win and rhev-tools-setup files can be accessed via the following symbolic links on the file system of the Red Hat Virtualization Manager:
/usr/share/virtio-win/virtio-win.iso/usr/share/virtio-win/virtio-win_x86.vfd/usr/share/virtio-win/virtio-win_amd64.vfd/usr/share/rhev-guest-tools-iso/rhev-tools-setup.iso
These image files must be manually uploaded to ISO storage domains that were not created locally by the installation process. Use the
engine-iso-uploader command to upload these images to your ISO storage domain. Once uploaded, the image files can be attached to and used by virtual machines.
