# How to start a live server installation on IBM Power (ppc64el) with a virtual CD-ROM and Petitboot
```{note}
Not all IBM Power machines come with the capability of installing via a virtual CD-ROM! However, it is also possible to [boot the installer over the network](netboot-the-live-server-installer-on-ibm-power-ppc64el-with-petitboot.md).
```
A separate system (ideally in the same network, because of `ipmitool`) is needed to host the ppc64el ISO image file, which is later used as the virtual CD-ROM.
## Install ipmitool and Samba
Log in to this separate host and make sure that the `ipmitool` package is installed:
```
$ sudo apt install ipmitool
```
as well as Samba:
```
$ sudo apt install samba
```
## Configure Samba
Next, set up and configure Samba:
```
$ sudo touch /etc/samba/smb.conf && sudo tee -a /etc/samba/smb.conf < **Optional step**
> For downloading the image you may have to use a proxy server:
> ```
> $ sudo touch ~/.wgetrc && sudo tee -a ~/.wgetrc < use_proxy=yes
> http_proxy=squid.proxy:3128
> https_proxy=squid.proxy:3128
> EOF
> ```
## Download the ISO image
The ISO image needs to be downloaded now:
```
$ wget http://cdimage.ubuntu.com/ubuntu/releases/focal/release/ubuntu-20.04-live-server-ppc64el.iso --directory-prefix=/var/winshare
```
The proxy can also be passed over as a `wget` argument, like this:
```
$ wget -e use_proxy=yes -e http_proxy=squid.proxy:3128 http://cdimage.ubuntu.com/ubuntu/releases/focal/release/ubuntu-20.04-live-server-ppc64el.iso --directory-prefix=/var/winshare
```
Change the file mode of the ISO image file:
```
$ sudo chmod -R 755 /var/winshare/
$ ls -l /var/winshare/
-rwxr-xr-x 1 ubuntu ubuntu 972500992 Mar 23 08:02 focal-live-server-ppc64el.iso
```
## Restart and check Samba
Next we need to restart and check the Samba service:
```
$ sudo service smbd restart
$ sudo service smbd status
● smbd.service - Samba SMB Daemon

```
Test Samba share:
```
ubuntu@host:~$ smbclient -L localhost
WARNING: The "syslog" option is deprecated
Enter WORKGROUP\ubuntu's password:
Sharename Type Comment
--------- ---- -------
print$ Disk Printer Drivers
winshare Disk
IPC$ IPC IPC Service (host server (Samba, Ubuntu))
Reconnecting with SMB1 for workgroup listing.

WORKGROUP host
```
Get the IP address of the Samba host:
```
$ ip -4 -brief address show
lo UNKNOWN 127.0.0.1/8
ibmveth2 UNKNOWN 10.245.246.42/24
```
> **Optional step**:
> Additional testing to make certain the Samba share is accessible from remote:
> ```
> user@workstation:~$ mkdir -p /tmp/test
> user@workstation:~$ sudo mount -t cifs -o
> username=guest,password=guest //10.245.246.42/winshare /tmp/test/
> user@workstation:~$ ls -la /tmp/test/
> total 1014784
> drwxr-xr-x 2 root root 0 May 4 15:46 .
> drwxrwxrwt 18 root root 420 May 4 19:25 ..
> -rwxr-xr-x 1 root root 1038249984 May 3 19:37 ubuntu-20.04-live-server-ppc64el.iso
> ```
Now use a browser and navigate to the BMC of the Power system, which should be installed (let's assume the BMC's IP address is `10.245.246.247`):
```
firefox http://10.245.246.247/
```
Log into the BMC, then find and select:
> Virtual Media --> CD-ROM
Enter the IP address of the Samba share:
> 10.245.246.42
and the path to the Samba share:
```
\winshare\focal-live-server-ppc64el.iso
```
Click "Save and Mount". Make sure that the virtual CD-ROM is really properly mounted!
```
CD-ROM Image:
This option allows you to share a CD-ROM image over a Windows Share with a
maximum size of 4.7GB. This image will be emulated to the host as USB device.
Device 1 There is an iso file mounted.
Device 2 No disk emulation set.
Device 3 No disk emulation set.
```
```
Share host: 10.245.246.42
Path to image: \winshare\focal-live-server-ppc64el.iso
User (optional):
Password (optional):
```
````{note}
It’s important that you see a status like this:
```
Device 1 There is an iso file mounted
```
Then the virtual CD-ROM is properly mounted and you will see the boot/install from CD-ROM entry in Petitboot:
```
[CD/DVD: sr0 / 2020-03-23-08-02-42-00]
Install Ubuntu Server
```
````
## Boot into the Petitboot loader
Now use `ipmitool` to boot the system into the Petitboot loader:
```
$ ipmitool -I lanplus -H 10.245.246.247 -U ADMIN -P power status
$ ipmitool -I lanplus -H 10.245.246.247 -U ADMIN -P sol activate
$ ipmitool -I lanplus -H 10.245.246.247 -U ADMIN -P power on
Chassis Power Control: Up/On
```
And reach the Petitboot screen:
```

```
And let Petitboot boot from the (virtual) CD-ROM image:
