To install NFS

Check whether the nfs service is installed or not, using the following command

[root@linuxhelp Desktop]# rpm -qa | grep nfs
nfs4-acl-tools-0.3.3-7.el6.x86_64
nfs-utils-1.2.3-70.el6.x86_64
nfs-utils-lib-1.1.5-11.el6.x86_64

If the service is not installed, use the following command to install it.

[root@linuxhelp ~]# yum install nfs-utils &ndash y

Start the NFS services using the following command.

[root@linuxhelp ~]# chkconfig nfs on
[root@linuxhelp ~]# service rpcbind start
[root@linuxhelp ~]# service nfs start

Create a new directory for placing the ISO file

[root@linuxhelp ~]# mkdir /ISO
[root@linuxhelp ~]# vim /etc/exports

Now edit the /etc/exports file

/ISO           192.168.7.0/24(rw)

Save and exit the file.
Run the following command to reload the nfs config.

[root@linuxhelp ~]# exportfs -a

Change the ownership of the directory to uid:36 and gid:36.

[root@linuxhelp ~]# chown 36:36 /ISO
The 36 is the uid of vdsm user “ RHEVM agent”  and the gid of kvm group.

Now create a new storage with NFS/ISO configuration

Select the Data-center&rarr Storage&rarr New domain

Now the ISO domain is created and upload the iso files in the new domain.

Transfer the iso file to the rhevm machine under the ISO directory and use rhevm-iso-uploader command to upload it.

[root@linuxhelp ~]# rhevm-iso-uploader  upload -I  ISO  Ubuntu-16.04-amd64.iso
Upload
Ubuntu-16.04-amd64.iso uploaded successfully

After uploading check the ISO file in the rhevm web interface.
