Discovery

Change PXE global temlate

set it to discovery

Add a subnet

i use the maximum range here, but you dont need to if you have multiple hostgroups

keep in mind that this is limited by your dhcp-settings

Build PXE default template

click on A)

also make sure to add the proxy to your subnet:

Boot a machine via PXE i was to lazy to setup kvm and libvirt so i used my server here if everything works, you dont need to do anything: just let it run

if your subnet and settings are correct it should boot:
- the Boot Image will configure NIC manually: - waiting time is quite long, but thise way boot wont fail
- the host gets discovered:
- our discovered host is ready to get provisioned:

## Provisioning

we need a os:

it also needs a partition table:

clone the Provisioning template:

click on B)

we need to add a os to it:

add a Hostgroup
select our subnet:
- for simplicity i just choose my default os as the hostgroup’s os:
now we can create a host from the machine that was discovered before
you need to click on provision in the Discovered Host’s section
- we select our hostgroup main which we created before:
- in the Host section we need to select our proxy and hostgroup:
- add a password to the host and finish the provision process:
