C.2. Creating a Red Hat Enterprise Linux 7 Image

Copy the Red Hat Enterprise Linux binary ISO file to the /var/lib/libvirt/images/ directory.

[root@host]# cp ~/home/user/Downloads/rhel-server-7.4-x86_64-dvd.iso /var/lib/libvirt/images/

Verify that virtbr0 is the virtual bridge:

[root@host]# ip a

Start libvirtd:

[root@host]# systemctl start libvirtd

Navigate to the /var/lib/libvirt/images/ directory:

[root@host]# cd /var/lib/libvirt/images/

Prepare the QEMU image:

[root@host]# qemu-img create -f qcow2 rhel7.qcow2 8G

Start the installation using virt-install. Use the following example as a guide:

[root@host]# virt-install --virt-type qemu --name rhel7 --ram 2048 \
--cdrom rhel-server-7.4-x86_64-dvd.iso \
--disk rhel7.qcow2,format=qcow2 \
--network=bridge:virbr0 --graphics vnc,listen=0.0.0.0 \
--noautoconsole --os-type=linux --os-variant=rhel7

[root@host]# virt-manager

Follow the steps of the Red Hat Enterprise Linux installation wizard.

Confirm that the network interface is up and that the IP address is assigned:

# ip a

Confirm that the hostname is correct:

# hostname

Create a /etc/NetworkManager/conf.d/XX-cloud-image.conf file where XX is a two-digit number that indicates order of precedence. Add the following contents to the file:

[main]
dns=none
