Calling Debian Stretch & Mellanox Experts

@travisdh1 was just posting yesterday about how he'd never use ZFS or BtrFS for virtualization since they are so slow.
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.

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.
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". -
The only advantage to ProxMox I see is the specific owners for VMs(can do it through polkit but it's annoying). Also a small portion the fact that there is a usable web interface but it's been years since I've used it. I use cli and Virtual-Manager, but it is annoying if you try to manage from a Windows machine.
If all they did was create a web interface it would be much better.
I'll never understand the point of ZFS for a hypervisor. Better snapshotting is available through libvirt and that's the only thing I see people say they use it for.

The Proxmox GUI is via a web interface

Ask @scottalanmiller about the cult of ZFS! People love their ZFS!!

Right. I mean if that's all they did it would be ok, not create a whole distro.

It's true. And @kooler has identified the same thing with CEPH. I see a new article coming

I agree. As just a management interface it could be pretty nice.

If I remember correct they put a lot of red hat kenrel in it. Not straight Debian kernel at all. But I've checked it a lot of months ago.

That seems like a really odd thing for them to have done.
