Using a virtual CDROM and Petitboot to start a live fun88体育 installation on IBM Power (ppc64el)
There is also documentation on booting the installer over the network.
-
Notice:
Not all IBM Power machines come with the capability to install via a virtual CDROM ! -
A separate system (ideally in the same network, because of ipmitool) is needed to host the ppc64el ISO Image file, that is later used as virtual CDROM.
-
Login 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
-
Next is to setup and configure Samba:
$ sudo touch /etc/samba/smb.conf && sudo tee -a /etc/samba/smb.conf <<EOF [winshare] path=/var/winshare browseable = yes read only = no guest ok = yes EOF
And do a quick verification that the required lines are in:
$ tail -n 5 /etc/samba/smb.conf [winshare] path=/var/winshare browseable = yes read only = no guest ok = yes
-
(Optional)
For downloading the image you may have to use a proxy fun88体育:$ sudo touch ~/.wgetrc && sudo tee -a ~/.wgetrc <<EOF use_proxy=yes http_proxy=squid.proxy:3128 https_proxy=squid.proxy:3128 EOF
-
The ISO image needs to be downloaded now:
$ wget https://cdimage.www.ii0fi.com/ubuntu/releases/focal/release/ubuntu-20.04-live-fun88体育-ppc64el.iso --directory-prefix=/var/winshare
The proxy can also be passed over as wget argument, like this:
$ wget -e use_proxy=yes -e http_proxy=squid.proxy:3128 https://cdimage.www.ii0fi.com/ubuntu/releases/focal/release/ubuntu-20.04-live-fun88体育-ppc64el.iso --directory-prefix=/var/winshare
-
Change 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-fun88体育-ppc64el.iso
-
Restart and check the Samba service:
$ sudo service smbd restart $ sudo service smbd status ● smbd.service - Samba SMB Daemon Loaded: loaded (/lib/systemd/system/smbd.service; enabled; vendor preset: ena Active: active (running) since Tue 2020-02-04 15:17:12 UTC; 4s ago Docs: man:smbd(8) man:samba(7) man:smb.conf(5) Main PID: 6198 (smbd) Status: "smbd: ready to serve connections..."

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 fun88体育 (Samba, Ubuntu)) Reconnecting with SMB1 for workgroup listing. fun88体育 Comment --------- ------- Workgroup Master --------- ------- 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)
Even more testing if 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-fun88体育-ppc64el.iso
-
Now use a browser and navigate to the BMC of the Power system that should be installed (let’s assume the BMC’s IP address is 10.245.246.247):
firefox https://10.245.246.247/
-
Login to the BMC and find and select:
Virtual Media --> CDROM -
Enter the IP address of the Samba share:
10.245.246.42
and the path to the Samba share:\winshare\focal-live-fun88体育-ppc64el.iso
-
Click Save and Mount
(make sure that the virtual CDROM 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. <Refresh Status>
Share host: 10.245.246.42 Path to image: \winshare\focal-live-fun88体育-ppc64el.iso User (optional): Password (optional): <Save> <Mount> <Unmount>
-
Notice:
It’s important that you see a status like:Device 1 There is an iso file mounted
Only in this case the virtual CDROM is properly mounted and you will see the boot / install from CDROM entry in petitboot:
[CD/DVD: sr0 / 2020-03-23-08-02-42-00] Install Ubuntu fun88体育
-
Now use the ipmitool to boot the system into the petitboot loader:
$ ipmitool -I lanplus -H 10.245.246.247 -U ADMIN -P <password> power status $ ipmitool -I lanplus -H 10.245.246.247 -U ADMIN -P <password> sol activate $ ipmitool -I lanplus -H 10.245.246.247 -U ADMIN -P <password> power on Chassis Power Control: Up/On
-
And reach the Petitboot screen:
Petitboot (v1.7.5-p8f5fc86) 9006-12C BOS0026 ───────────────────────────────────────────── [Network: enP2p1s0f0 / ac:1f:6b:09:c0:52] execute netboot enP2p1s0f0 (pxelinux.0) System information System configuration System status log Language Rescan devices Retrieve config from URL *Plugins (0) Exit to shell ───────────────────────────────────────────── Enter=accept, e=edit, n=new, x=exit, l=language, g=log, h=help Default boot cancelled
-
And make sure that booting from CDROM is enabled:

Now select the ‘Install Ubuntu fun88体育’ entry below the CD/DVD entry:
[CD/DVD: sr0 / 2020-03-23-08-02-42-00] * Install Ubuntu fun88体育
-
And let Petitboot boot from the (virtual) CDROM image:
Sent SIGKILL to all processes [ 119.355371] kexec_core: Starting new kernel [ 194.483947394,5] OPAL: Switch to big-endian OS [ 197.454615202,5] OPAL: Switch to little-endian OS
-
Finally the initial subiquity installer screen will show up in the console:

The rest of the installation is business as usual …
