Comparison of virtualization feature set: XCP-NG vs PVE (Proxmox) -- VMware migration decision

[floh8]

Many people search for a comparison between the last affordable virtualization solution in the market Proxmox PVE and xcp-ng. Lawrence Systems offers a good but incomplete summary. So here are a more detailed feature comparison of these both hypervisor solutions.



Some information to xcp-ng, xostor, xo and Vates:

XCP-ng is a virtualization platform incubated within the Xen Project as XenServer fork and hosted by the Linux Foundation. Vates is the company that develop the xen orchestra (xo) a open source Web-Admin-UI for xcp-ng with additional features like VM replication, VM backup aso. xostore is a project of xcp-ng to offer HCI functionality with Linbints "Linstor" based on DRBD and free included in the xcp-ng product. Vates offer a bundle consisting of a stable release of xo (called xoa) with a Web-Admin-UI for xostor and professional support.

From my perspective:

killer feature of PVE:

• integraded HCI with ceph
• zfs-over-iscsi storage
• integraded firewall for host and VMs
• awesome gui with most functions

killer feature of xcp-ng:

• stability
• 24/7 support
• complete load balancing
• VM backup with important functions

Hi. I don't quite understand this particular position in the comparison:

"costs for 3 nodes: PVE: 115 e pro socket / year; XCP-ng: free [...] ".

Am I wrong that a plan with a support is not free for XCP-ng, too?

xcp-np supports XOStor (drbd.) regardless of how you feel about drbd, it is fully supported.

snapshot space efficiency for block storage

please explain. I am unfamiliar with this.

Not sure where OP got that from; https://vates.tech/en/pricing-and-support/

Gluster isn't supported any more since PVE 9

Hi,

Also proxmox have free options, and the node limit is not 32 it's just that with a high number of nodes tweaking is needed (Cf : https://forum.proxmox.com/threads/proxmox-with-48-nodes.174684/#post-812204).

And the used file format is not only qcow2, there is also raw (storage dependent).

Best regards,

Hi,
below are my 2 cents

As far as I know there is also a linstoreplugin for DRBD available in PVE.

Does xcp-ng also provide similar fine grained api for permission settings on ressource pools for delegated administration? Which external authentication is available, that matters to you?

How is the plan for backup and restore?

I would consider VM isolation within PVE also very high, because you can set appamour profiles via hookscripts on KVM process starts.

How is the community size and the availability/distribution of plattform expertise in your region.

Is PCIexpress pass through a matter? E.G. for serial interfaces or GPUs?

Hope my view/questions are not to single minded. I am not familiar with xcp-ng and would be very interested in the answers.
