[ovirt-users] oVirt NGN image customization troubles

[Yuval Turgeman]

Recent versions of livemedia-creator use qemu directly instead of libvirt,
and I think I saw a problem there also, but didn't get to fix it just yet.
You can use virt-builder to install a centos vm, or use an el7-based mock
environment.  You can follow the jenkins job here [1], basically you need
to do is:

1. clone ovirt-node-ng (you already did)
2. clone jenkins
3. cd ovirt-node-ng
4. ../jenkins/mock_configs/mock_runner.sh --build-only --mock-confs-dir
../jenkins/mock_configs/ --shell 'el7.*x86_64'

This will create a chroot environment in the same way we do in our CI, in
that chroot shell, do `cd ~` and then autogen, and make squashfs....
