I don’t think so, now. You’ll have to do those yourself.

Which means my distro-morphing idea should work in theory with OpenStack
I don’t recommend doing a manual install though, as it’s extremely complex compared to automated deployment solutions like kolla-ansible, openstack-ansible, or openstack-helm/genestack. They make the install much more simpler and less time consuming, while still being intensely configurable.
- Comment on XCP-NG vs PROXMOX security hardening? 3 weeks ago:
Personally, I think Proxmox is somewhat unsecure too.
Proxmox is unique from other projects, in it’s much more hacky, and much of the stack is custom rather than standards. Like for example: For networking, they maintain a fork of the Linux’s older networking stack, called
ifupdown2, whereas similar projects, like openstack, or Incus, use either the standard Linux kernel networking, or a project calledopenvswitch.I think Proxmox is definitely secure enough, but I don’t know if I would really trust it for higher value usecases due to some of their stack being custom, rather than standard and mantained by the wider community.
If I end up wanting to run Proxmox, I’ll install Debian, distro-morph it to Kicksecure
If you’re interested in deploying a hypervisor on top of an existing operating system, I recommend looking into Incus or Openstack. They have packages/deployments than can be done on Debian or Red Hat distros, and I would argue that they are designed in a more secure manner (since they include multi tenancy) than Proxmox. In addition to that, they also use standard tooling for networking, like both can use Linux Bridge (in-kernel networking) for networking operations.
I would trust Openstack the most when it comes to security, because it is designed to be used as a public cloud, like having your own AWS, and it is deployed with components publicly accessible in the real world.

Firstly, Xen is considered by secure by Qubes — but that’s mainly the security of the hypervisor and virtualization system itself. They make a very compelling argument that escaping a Xen based virtual machine is going to be more difficult than a KVM virtual machine.
But threat model matters a lot. Qubes aims to be the most secure OS ever, for use cases like high profile journalists or other people who absolutely need security, because they will literally get killed without it.
Amazon moved to KVM because, despite the security trade off’s, it’s “good enough” for their usecase, and KVM is easier to manage because it’s in the Linux kernel itself, meaning you get it if you install Linux on a machine.
In addition to that, security is about more than just the hypervisor. You noted that Promox is Debian, and XCP-NG is Centos or a RHEL rebuild similar to Rocky/Alma, I think. I’ll get to this later.
Xen (and by extension XCP-NG) was better known for security whilst KVM (and thus Proxmox)
I did some research on this, and was planning to make a blogpost and never got around to this.

default PROXMOX and XCP-NG installations.
What do you mean by hardening? If you are talking about hardening the management operating system (Proxmox’s Debian or XCP’s RHEL-like), or the hypervisor itself?
I agree with the other poster about CIS hardening and generally hardening the base operating system used. But I will note that XCP-NG is more designed to be an “appliance” and you’re not really supposed to touch it. I wouldn’t be suprised if it’s immutable nowadays.
For the hypervisor itself, it depends on how secure you want things, but I’ve heard that at Microsoft Azure datacenters, they disable hyperthreading because it becomes a security risk. In fact, Spectre/Meltdown can be mitigated by disabling hyper threading. Of course, their are other ways to mitigate those two vulnerabilities, but by disabling hyper threading, you can eliminate that entire class of vulnerabilities — at the cost of performance.

The documentation has long since been changed.
Note that the anon user is able to become root without a password by default, as a development convenience. To prevent this, remove anon from the wheel group and it will no longer be able to run /bin/su.

Freshtomato is not out of date. It looks like the last release was december of 2024
Perhaps you are confusing freshtomato with some of it’s predecessors, like tomato or advancedtomato, which are no longer currently maintained.
As for openwrt instead, that doesn’t support broadcom wifi chips, whereas freshtomato does.

This is like that other recommendation of a linuxserver/kasmvnc docker image as well. It doesn’t allow for collaborative editing like cryptpad or google docs does.
