Looks like this is similar to
https://bugzilla.redhat.com/show_bug.cgi?id=1245960

and probably depends on something unique in your environment. As adam
said, running it inside a mock is safer, or if you have libvirt setup
you could use that with a f24 boot.iso to further isolate things.

I've taken the example from Fedora Wiki and made litlle customizations:

http://pastebin.com/MWDczEis


VirtualBox was opened at moment of running lmc, but then I even closed and
the errors persisted...

Any ideas?

Thanks in advance!

...which looks like you used a kickstart intended for installing to
VirtualBox or something. The live media kickstarts are kind of a
specific layout and it's really best to start from one of the official
kickstarts when building a live image, rather than starting from a
typical system installation kickstart.

Hi Adam,

Thanks for your clarifications

You can take a look at http://pastebin.com/U3RPX0qK (Anaconda log)

Meanwhile I will use system-config-kickstart

Greetings

...well, okay, that's a lie. It actually creates the image file, then
either attaches it to a VM and runs the install in the VM (virt mode)
or mounts it and runs an anaconda directory install into the mounted
path (novirt mode), so either way, the image now contains an installed
system. Once anaconda is done it twiddles about a bit more with the
image.

That error means the anaconda install failed. The way livemedia_creator
works is that it actually runs an anaconda install using the kickstart
specified - using its 'install to a directory' method if you pass --no-
virt, otherwise in a VM - then creates an image file from the resulting
installation.

You'd need to look at the generated log files, probably anaconda.log ,
to see what exactly went wrong.

I'd probably advise against running livemedia-creator with the --no-
virt option in your actual production environment, it could potentially
cause problems. The way I've found to make lmc fly (though it's a bit
awkward, and I need to get around to writing some scripts to make it
more convenient) is to mimic what Koji does for production builds, and
run it in a mock chroot. Basically, set up a clean mock chroot of the
release you actually want to create a live image for, install the
creation tools into the mock root with 'mock -r (whatever) --install
livemedia-creator' (and whatever other packages are needed, I forget)
then run 'mock -r (whatever) --shell' and do the live image creation
inside the shell. It's been a few weeks since I did this so I forget a
few annoying twiddly details you run into along the way, but that
basically worked for me.

I actually just steal the kickstarts from Koji - you can just grab a
kickstart from a completed official live image task, and customize it
if you want. I find that easier than trying to generate the flattened
kickstarts lmc wants...

Hope that helps a bit, anyway...
