Proxmox VE or XenServer; Which Do You Recommend?


One of the most popular comparisons on IT Central Station is Proxmox VE vs XenServer 

Which of these two solutions would you recommend for Server Virtualization Software? Why?

Thanks!

My 5 cents : Go with Proxmox .
It is NOT just a wrapper for KVM, it has a lot of features that are not present in plain KVM .
It is extremely easy to set it up, you can have a 16 node cluster up and running in a single day of work !
Everything you need to manage your storage space, whatever it is, shared or centralized, CEPH, DRBD, iSCSI, NFS, ZFS or any other File System supported by Linux .
You even have some VDI oriented features .
The web interface are straightforward and very intuitive .
All of it with less than a half of the cost of XEN ( or a mere fraction of the cost of VMWare or HyperV )
I am using it for 10 years or so, since 2.2 version .
And, you can try it without any cost or vendor support, just download the image and install, use it for a month, if you thing that Proxmox do not have all the features you need, then go to something else. it won't hurt your budget .

It's easy, with the new version of XenServer you lose several features that you will need on production: https://xenserver.org/blog/entry/xenserver-7-3-changes-to-the-free-edition.html
Use Proxmox VE. :)

I'm afraid that I cannot say anything about XenServer, but we are using Proxmox ourselves and at a customer site. Both installations are rather small (6 and 3 nodes), based upon version 4 and 5. We are very happy with the systems: reliable, performant and extremely easy to use. For cost reasons, we are using the Proxmox nodes also for the CEPH cluster, which may not be an optimal solution - but it works very well. The only drawback is that we decided to choose hard disks instead of SSDs; this way the I/O performance is not as good as with a native system, but it's sufficient.

From our point of view, we would go for Proxmox again, and we actually plan to build two more clusters - but as I said, I cannot compare.

I've used vSphere, KVM, Proxmox and Hyper-V. I have to say I like KVM the best because it is immensely customizable, updates move fast (or as slow as you want - just config your repositories appropriately), is dead-easy to configure using libvirt, can use any file system available to Linux (I use ZFS, but have also had good results with XFS), etc. Has a learning curve if you're new to Linux but it's entirely worth it. I hate vendor lock-in and proprietary software, it always comes back to bite you in the end. vSphere is the worst regarding vendor lock-in, Hyper-V second, Proxmox third. Haven't used Xenserver, but I imagine it has similar issues. Learn how to configure Linux - the skills are transferable and the possibilities are limitless.

I appreciate you reaching out to me on this. I, unfortunately, have not installed, tested or see Proxmox VE. I have performed many deployments of XenServer using both iSCSI and FC. The XenServer product is easy to manage and install and will provide more mainstream support. Meaning, if there is an issue with an aspect within the deployment, you will most likely be more able to find support through the communities, blogs and Citrix documentation than you will for the other product.

There is a larger corpus of XenServer deployments in my estimation than there is for the Proxmox VE product. I would suggest the engineer below does their due diligence and installs the products in a lab environment. Then perform a bake-off of sorts. This will enable them to gain further insight to the capabilities, drawbacks and sometimes incompatibilities that they may not have been aware of.

XenServer supports lots of hardware, it is secure, easy to deploy, manage and operate. It has many similar features to VMware, but it also lends itself well to existing Citrix XenApp and XenDesktop environments already in production to facilitate a few more feature add-ons and performance enhancements. XenServer is a good product, it just lags behind the other major player Hyper-V and VMware due to a lack of marketing in my opinion.

I hope this helps and good luck.

I use XenServer mainly because I used Xen from an early stage plus it was opensource. Also, it can be used on Debian. I never used Proxmox VE so cannot give any tips on it.

I've never used Proxmox VE. I read about Promox and it looks like Microsoft Virtual Machine Manager and VMware vCenter.

XenServer is a great solution, but the cost of licensing is complex and higher than VMware and hyper-v. One problem is that there are few XenServer experts.

For critical virtualization environments, I prefer two solutions, VMware or Hyper-V. Choosing one of two solutions depends on how much budget you have for the project and how the infrastructure will be managed.

Pay attention to the price of licenses/support and renewal after 3 years. Many times the purchase is low value, but the renovation costs 3x the value of the purchase.

ProxmoxVE, always. It is the most stable system.

I am more fond of XenServer myself when used with some other things like pos it has the ability to cache images etc if your using that technology. I have used xenserver for large enterprises with no issues over the past 10 or so years. If you are using Citrix in conjunction with it xenserver 7.1 is the new LTSR that will be supported for the next 5 - 10 years dependent on which maintenance model you use..

Proxmox VE or XenServer: compare to pricing and some feature I will recommend to Proxmox VE

Proxmox for speed of setup and flexibility.

I’ve used XenServer

It does what it was on the tin

Dynamic allocations of data and applications are better than VMware or App V.

Even better if Citrix gives the bulk discounts

we are using VMware (https://www.itcentralstation.com/products/vsphere?tid=il-q) for server virtualization. it has strong other tools such as Vcenter or Vrealize for source monitoring. I don't have any experience with the other products

xenserver is the only option.

I agree with Sanford. VMware still has the only enterprise ready server virtualization layer.

I would Perfer Xen Server as many fact. First free and many features. Yes Promox is good as it is new but new technology takes some time to kick in. with Xen Servers you have many features Cloud Cluster Etc. So in my experince i would perfer Xen.

I havent used either software in a while but all in all, it depends on uptime and risk

So my advice is, do your homework:

- How much does a lost production hour cost?
- What is your competence level in your product you choose?
- If you get stuck, where can you find support?

And based on the outcome of these questions make a decision.

Hi, you can go with either one for simple or advanced scenarios. Xen used to be a better choice when you had to rely on automation tasks. Proxmox has grown to be capable of these tasks, and also has integration with ansible, ceph storage and others. You can manage it with either a command line or a browser. So Proxmox will be a better choice.

I have three server of virtualization running. One using Xenserver and another two using hyper-v server core 2016.
For windows aplications the hyper-v is wonderfull, but if want solution about citrix how xenapp, and xendesktop, definily use xenserver. It is clear that each scenario must have a prior evaluation before.
I hope help you!

I've never heard of Proxmox, but looks like it's just a wrapper around KVM. We've used XenServer for 10 years and Hyper-V for 5 years. XenServer works great and it has support from Citrix. But if you are serious about virtualizing, use VMware. We've had nothing but problems trying to get a reliable hypervisor-level backup product to backup 150 VMs on a 4-server cluster. VMware is just so much more mature and has great 3rd party software support.

Both are great. Xen is a little easier to learn but both will get the job done. Xen recently changed their free solution to not have as many features. It's more on par with Proxmox for features in the free solution now.

Vmware, then Hyper-V, then physical, because the other options are not enterprise worthy

I would think a better comparison would be Red Hat Enterprise Virtualization (RHEV https://www.itcentralstation.com/products/rhev?tid=il-q) vs Proxmox VE.
However, I don’t have any experience with either of these two products or XenServer, as we use VMware internally.
