I tested it once years and years ago. hated it and never touched it again.
JB, it might be time to test again.
It looks like it has some promise...
I'm only in the very early stages of testing, but I do like that I can have the hypervisor o/s installed on ZFS Raid1 & build a hyperconverged Ceph cluster for VM storage.Why do you want either ZFS or CEPH for that use case?

No HW RAID cards?

I hope you've more than that to offer. KVM and Xen do hardware RAID free options already but without the problems of ZFS or CEPH. What else do you have?

@travisdh1 was just posting yesterday about how he'd never use ZFS or BtrFS for virtualization since they are so slow.
-
Proxmox has a history of randomly breaking things, which is why I switched to XenServer when that was open sourced.

And a history of trolling to promote the product with fake accounts. It's a weird product with a bad online track record. It's KVM with weird stuff piles on top. Give me straight KVM any day.
-
Native KVM will to ZFS, XFS, BtrFS, CEPH, DRBD or Starwind as well. None of that stuff comes from ProxMox.

You could install Debian 8.3, and then do a manual install of Proxmox on top of that. I honestly don't want to touch Proxmox again.
Can you really layer ProxMox on top of something else? Never looked at it as an add on service before.
What distro does ProxMox build on natively.

No ZFS for virtualization!

Right. No ZFS for virtualization. Although I argued that its speed problems aren't as bad as it seems. Still, XFS for me unless a specific need arises.

AFAIK, it's built on Debian

ZFS and BtrFS really are adequately fast in most use cases. Nearly all. You lose some speed but if chosen for other reasons they are good options.

Looks that way.
-
Yeah, when we were running Proxmox here, I had to use the manual install method because they don't include drivers for a lot of network cards out of the box.
Install Debian -> Install Network Drivers (if needed) -> install Proxmox via repositories
Just one of many broken things about it (the network cards were on the HCL at the time).
-
From Mellanox it looks like the issue is just that Debian and ProxMox are not well supported. No surprise as those aren't really enterprise platforms. Debian is great but you get Ubuntu if you want enterprise Debian. And PM.... well, Id put it was a hobby system.
If you use RHEL, CentOS, Fedora, Ubuntu or Suse it looks like you can be fully updated and supported with Mellanox.

Proxmox isn't even a hobby system, to me it's a never use.
-
You might want to ping Mellanox support to see if they have something more recent for Debian that just isn't in the rralase notes yet. But my advice is to steer clear of ProxMox. This is the kind of problem I'd expect you to run into often.

Well I never deploy hobby systems

If you want a scale out, no hardware RAID, hyperconverged KVM option, you might want to think about something like Fedora with KVM, use MD RAID, XFS, then add in the new Starwind Linux VSA for KVM.

Problem solved.
Had to change both ports on the ConnectX-3 from the default of "IB" to "Eth".
