failure screenshot

Try to install ALP bedrock via pxe, but it boot failed with dracut failure
grub menu setting:
menuentry 'alp IPv4 Installation' --class opensuse --class gnu-linux --class gnu --class os {
	set gfxpayload=keep
	echo 'Loading kernel ...'
	linuxefi /alp/linux rd.kiwi.live.pxe root=live:http://192.168.111.1/d-installer-live.x86_64-0.8.3-ALP-Build11.1.iso rd.neednet=1 rd.live.overlay.persistent rd.live.overlay.cowfs=ext4
	echo 'Loading initial ramdisk ...'
	initrdefi /alp/initrd
}

If the boot parameter is incorrect, please help correct it, thanks.

The `root=live:URL` command line parameter requires the dracut `livenet` module (it should be listed with `lsinitrd -m /dir/with/alp/initrd`).

But, I think Agama (the ALP installer) does not use dracut to boot via PXE:

Thomas, am I right?

Indeed, compared to an older version of the installer:

-->
Version: dracut-059+suse.375.gafb362e4-1.1

Arguments:  --verbose --no-hostonly --no-hostonly-cmdline --install '/.profile' --add ' dmsquash-live livenet pollcdrom ' --omit ' multipath '

dracut modules:
bash
systemd
systemd-initrd
dbus-daemon
dbus
i18n
network-manager
network
url-lib
btrfs
crypt
dm
dmsquash-live
kernel-modules
kernel-modules-extra
kernel-network-modules
livenet
--<

The dmsquash-live and the livenet modules are missing:.
Instead there is the kiwi-live module:

-->
Image: loader/initrd: 81M
========================================================================
Version: dracut-059+suse.360.g2e0ed5f7-3.7

Arguments:  --verbose --no-hostonly --no-hostonly-cmdline --install '/.profile' --add ' kiwi-live pollcdrom ' --omit ' multipath '

dracut modules:
bash
systemd
systemd-initrd
dbus-daemon
dbus
i18n
network-manager
network
btrfs
crypt
dm
kernel-modules
kernel-modules-extra
kernel-network-modules
kiwi-live
-->

But the rootscript:

kiwi-live-root.sh

does not cover remote image boot.

Actually, the installer initrd is created via dracut now.
pxeboot is possible by extracting the kernel and initrd from the live image and providing them via pxe or ipxe.

On my testsystem, I could successfully boot the old installer image via the parameters:

root=live:ftp://myftpserver.suse.com/agama-live.x86_64.iso rd.live.image 

using the new installer image fails with the error message reported above.
So, I guess the installer initrd is broken, at least for netbooting the live image.

Thanks Thomas. Trying to assign it according to what I've seen in other similar bugs, Vincent please correct me if I'm wrong.

Closing.

Please rerun the test on SLES 16 once it's available.
