To be completely open, this is not a question about XCP-ng vs Proxmox. I’m open to doing everything in the cli, comparing two platforms is not my intention here.
I’m very interested in the security benefits one has over the other though. AFAIK Xen has a dedicated for security? I’d like to think that both are reasonably secure by default, but I do not get many hits for “KVM hardening”, for example, only OS-level hardening advice.
Do both protect equally against attacks that try to escape the VM? Is there anything in terms of security that one has and the other doesn’t?
I know this is not the usual kind of question that is asked on this sub, any help is greatly appreciated!
From the FAQ of Qubes OS (i.e. most secure desktop OS for general use):
“Why does Qubes use Xen instead of KVM or some other hypervisor?”
“In short: we believe the Xen architecture allows for the creation of more secure systems (i.e. with a much smaller TCB, which translates to a smaller attack surface). We discuss this in much greater depth in our Architecture Specification document.”
Thanks!
