No. For installing Ubuntu with FAI, I recommend using a Debian
nfsroot. Several FAI users are using this approach.

Yep, -l was removed from fai-make-nfsroot, since live-boot support was removed.

fai wikie: installing ubuntu

[John G Heim]

The fai wikie page on installing ubuntu says "-l is passed to 
fai-make-nfsroot makes it use 'live-boot instead of dracut, which is not 
supported by ubuntu. " but -l is not a legal option for 
fai-make-nfsroot. Is the documentation just out of date?

Re: LVM not working.

[Thomas Lange]

OK, I've solved this problem. I seems that the old CENTOS7_64.tar.xz
basefile in http://fai-project.org/download/basefiles/ caused all the
problems. I've created a new one, which now works.

Using this patch, you can now add the FAI class LVM to your CentOS
install client and use a LVM partitioning with CentOS 7.

That's very interesing.

Very strange.

It boots fine for me if I use a simple disk partition scheme.
I did set up a local yum repo. I never got it to work using the default.

I seems that the whole CentOS 7 installation is not working atm.
Even if you do not use LVM, the machine does not manage reboot
successfully. Booting the rescue kernel helps only a little bit.

AW: AW: AW: AW: AW: Problem with virtio network boot

[Denny Bortfeldt]

Hello everyone,

I could fix the problem. And here's the solution if you also got the problem:

VirtIO driver is included in the initrd, but when the VM boot into dracut the 
"dhclient" command fails. This happens, because of bad checksums with special 
software.
Currently we use qemu/kvm on out virtualization host and create the vms with 
"virt-install" and parameter "--pxe" for netboot. 
During netboot our DHCP-Server (dnsmasq) give the client an IP and this 
dnsserver got a little bug which was fixed in isc-dhcp already (standard dhcp 
in fai-installation). So nearly everyone should not have the same problem.

There are some solutions to fix the bad checksums bug:
- use isc-dhcp
- use e1000 driver instead during installation
- use an iptables-rule on the virtualization host(!!)
-- iptables -A POSTROUTING -t mangle -p udp --dport 68 -j CHECKSUM 
--checksum-fill

A special thanks to Thomas, who helped me a lot with nice hints!

Best regards,
Denny
