I'm a somehow experienced Debian user and new to CentOS. I'm managing a small HP server and somebody said that CentOS would be the better OS for this

I'm mainly using this server to run a couple of VMs using KVM/QEMU. Now, i'm trying to establish some backup concept but getting to the limits as I'm constantly getting an error message when trying to create a live image. The error message basically says that live snapshots are not supported by this version of qemu that I'm using.
I googled around a bit and it seems that this is a known problem and that the QEMU Version from the yum repos for CentOS does simply not contain this feature. I have no idea, why but this seems to be the situation.
Some posts suggest that I should replace my kvm-qemu package by the kvm-qemu-rhel package but there is not guidance on how to do this.
I'm really confused a bit. Is this a commmon thing under CentOS that the software is kind of castrated?
Coming to my main question: Is there a good way to install the RHEL packages under CentOS? Or will I have to live with this situation?
Thanks for your advice in advance
