Suggestion on Hypervisor to use on baremetal server
Hi guys am new here and also beginning my journey to server virtualisation.
I have a baremetal server with this spec.
Hardware-Data of the server
CPU/Processor: Intel Xeon E3-1270v3
CPU-Count: 1
CPU-Cores per CPU: 4
Logical Cores per CPU: 8
64Bit-Support CPU: yes
Virtualization-Support: yes
RAM: 32768 MB DDR3-RAM
HDD: 2 x 500 GB SSD
Hardware-RAID: no
Hardware-RAID level: no
Network data of the server
Network card 1
Speed: 1 Gbps
Network card 2
Speed: 1 Gbps
This server is for personal use and hosting a few personal client I manage and provide website services for.
Am thinking of going with Proxmox VE for type 1 Hypervisor simply because I can run KVM VPS as well as Linux containers. Am learning all things docker and kubernetes so I want option to be able to run ontainers side by side full KVM VPS.
Another option I was think was running Container Linux (CoreOS) on the baremetal.
What are you using and has worked for you? I would appreciate hearing your opinion, advice or recommendation as I would like to learn from your experiences.
Thank you

Hi @klassbond
I use Proxmox VE for multiple Host, I can highly recommend it to you. It has its quirks but i is quite easy to use, there is a nice GUI but you also can manage it over the console.
And if you want you can get paid support
+1 for Proxmox
Stable, Allow simple and advanced setups, upgradable, I got 3 which was upgraded to 4 then to 5 and when 5
Works as intended
Thank you very much for sharing your experience. I Wil give it a go. How usable is it as In running VMs and Containers side by side on the same bare metal host? Do you know if I am better off for the containers (docker, kubernetes) to run it on one VM inside the baremetal server?
That's good to hear. So upgrading wasn't too much pain without losing current set up? Of course I will backup before upgrading when it comes to that
+1 For Proxmox VE.
Yes it is just changing the Debian distribution name in the repos and running apt update
apt dist-upgrade
how ever for new install you will get 6 (Debian 10 Buster based) which mean that 3 years you will only do apt update and apt upgrade
If your server will be installed from your datacenter template and they got only 5 at the current moment as 6 is only couple of weeks old ... you can install 5 and try the upgrade process 1st hand
proxmox write it to
write it to look complicated it is not just change the repos apt cons https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0
Replace stretch with buster disable enterprise repo
run
apt update
apt dist-upgrade
when process start there is some question... I answer, No to samba , Yes to auto restart services
Yes to overwrite all services configs (except to sshd config) and by careful if it ask you grub question ... and reboot and cross fingers
You might need to mention what you have for IPv4 addresses to know your setup and limitations.
I've used proxmox a lot but am currently looking into openstack - although not got far enough with it to comment properly.
I should add I'm not experimenting with openstack due to problems with proxmox, it works fine and is easy to setup/use.
For security reasons, I would always run docker/kubernetes in a separate KVM VM and not directly on the VM host.
Hi Tim,
Thanks for your response. I have 20 IPv4 addresses, Can you elaboroate on what you by
** need to mention what you have for IPv4 addresses?**
Thanks
Thank you, good idea as i am planning this from a Privacy By Design approach.
Why? Why running VMs in a VM if you already have a Hypervisor on the Dedicated Server? It will hurt the performance of the nested VM and won't necessarily increase Privacy..
Proxmox, Vmware..
Run kubernetes / Docker instances in there own KVM / VMs.
Yes I already re evaluated that statement. Thanks.
Proxmox works. LXC are a blast for low-resource overhead if all containers are "yours". Would never recommend containers for buying as "VPS" from a provider, but if it's all your stuff within one server, they are pleasant to work with. Create/clone/start/stop/destroy are super quick, and barely any RAM is used for launching one more.
I still don't like that it uses (and I guess relies on) systemd, but I guess it should be possible to not have to dabble a lot in the host system, only use the actual guests, so I don't have to touch it (much).
@ruben @coolice it's decided Proxmox will do for me.
I have one other question. Do you have experience or encounter using Virtualizor for auto provisioning and Billing VM resources running in Proxmox?
I ask because I have 5 private clients I do bespoke Web projects for and ideally want to host VMs for them should my list continue growing. Virtualizor seems to have BLESTA/WHCM billing VM AutoProvisioning as well as integrated billing (in beta).
Thanks
You're good. I've seen people with a single IPv4 and they had to resort to port forwarding and IPv6.
Never tired them together on theory it shoud work but if you plan to host couple of private clients why do not host them in LXC it super light and has templates so it save you the 10-15 minutes ISO install
+1 for Proxmox
A platform you can simply rely on.
@BharatB
Pardon me but NO. Pretty much all those container systems have serious problems and add vulnerabilities rather than security or privacy.
@klassbond We have a budding product, https://hypervisor.io/ If you'd like I'll provide full support including installation + configuration. This is a KVM only platform for now with hourly billing support. If you're interested let me know.
That product will be better if it also supports Debian 10 (for the 5.0 kernel support)
I'm using Proxmox on my personal Home server. Running a Kunernetes cluster with 1 master and 2 nodes (3VMs spinned using Proxmox). No issues so far
I will give it a go
OK so what is better option out there? Not is 100% secure put I would like to know some of the flaws you have spotted and suggestions of what alternative you have in mind. This is still all research for me and am reviewing all options and looking at other alternative.
I stumbled upon SmartOS yesterday and reading up on the hpervior capabilities
Thank you. At this moment I am only looking at opensource solutions.
Sorry, but to list all the problems known with containers is too troublesome, so I'll summarize what I've learned so far: The are designed and coded poorly. Some developers have opened up about their situation.
Alternatives? Don't use them, simple.
As for SmartOS, I do like Solaris but at the end of the day you'll end up with KVM again, but with an OS whose community is very very small compared to Linux. Not exactly the smart choice for someone who is new to the field.
There are other options, too e.g. the hypervisors of some of the BSDs and of course the "security" hypervisors, but again with very small communities compared to Linux, and the few secure hypervisors that can be taken seriously typically require quite a bit of additional experience and know-how and are certainly not the smart choice for a beginner.
TL;DR Put some efforts into choosing the right Linux distro for you and go with KVM.
My second advice is to stay away from pre-packaged "easy to use" solutions with a GUI. Reason: Typically those come with many choices already made - some of which will later turn out to be different from what you would like.
Try XenServer. As @drserver can tell you, it offers best resource isolation. Also if you don't need to give your client's management access, your GUI is a neat Windows program - XenCenter.
Sod that! Bye bye any sense of security. :-|
