approc,

It's awesome to see the interest in getting CentOS 7.0 support. As
Sergii noted, the Mirantis  team doesn't have enough bandwidth to
certify CentOS 7.0 for Fuel 6.1 however I would love to help you get
started with some of this.

The barriers to moving between versions usually are:
a) major changes between releases. In this case the biggest issue will
be systemd
b) changes in the way configured packages behave due to version bumps
c) poorly behaving or performing packages

with regards to a, and b. they usually can be addressed in the
fuel-library manifests, c usually requires packages to be re-built.
I'd encourage you to look at issues from a,b.

how to start:

the most hacker way would be to goto the fuel-main repo and make an
iso with an CentOS 7 mirror

poking though the Makefile and configure.mk, it appears that you
should be able to overwrite MIRROR_CENTOS and MIRROR_CENTOS_KERNEL to
a public EL7 repo and it should start pulling what you need.

You may need to update requiremes-rpm.txt to match packages that might
have moved versions / names from EL6 to EL7

Please feel free to reach out to me on irc (xarses), via the ML or
directly if you need assistance.
