Doc Text:	With this update, the Anaconda image created by Lorax contains the bridge-utils packages, which allow dracut's bridge command to be supported during the installation process. As a result, the brctl utility is now available during the installation, and using bridge command-line options in the Pre-Boot Execution environment (PXE) works as expected.	Story Points:	---

Description Jan Kundrát 2015-02-03 18:56:20 UTC

I'm kickstarting a couple of headless servers, and I would like to preconfigure networking for OpenStack/libvirt/KVM. This implies support for bridging. Patching this ex-post through e.g. Puppet is a bit risky.

How reproducible:

1. Add any "bridge" option to a PXE boot.
2. Observe a "dracut: FATAL: No 'brctl' installed" and "dracut: Refusing to continue" failure.

The whole set of options I would like to use, in the end, is this:

ip=XYZ::ZYX:27:HOSTNAME:br0:none:9100 nameserver=NS bond=bond-te:enp3s0f0,enp3s0f1:mode=802.3ad,xmit_hash_policy=layer3+4 vlan=vlan121:bond-te bridge=br0:vlan121

That is:

- two eth interfaces with LACP bonding
- VLAN 121 over the bond-te
- this VLAN to be added as the only if to a bridge, which will be later on used by VMs

Please note that this is only about dracut's networking setup. A complementary solution would be to describe this setup over Anaconda's options in my kickstart file.

The install initramfs is composed by lorax and should probably be extended to include "brctl", which means bridge-utils have to be installed.

Comment 4 Michal Kovarik 2015-09-04 08:02:39 UTC

Verified on RHEL-7.2 Beta. Installation initrd.img contains usr/sbin/brctl

# lsinitrd initrd.img | grep brctl
cat: write error: Broken pipe
-rwxr-xr-x   1 root     root        32896 Aug 20 11:15 usr/sbin/brctl
