dracut-kernel should be there. As for kernel-firmware, on a CentOS 6
system there are two sources for it -- openvz repo and centos repo --
so you have do choose one.

The best bet would be openvz repo, in
order to use it you should comment out

    disable=vzkernel-firmware

line in /etc/yum.repos.d/openvz.repo

and add this to centos repo.
