Totally lost on versions

[Erwin123]

We decided to upgrade our nodes from proxmox 1.3 to 1.8.
So I took a look at the wiki:
http://pve.proxmox.com/wiki/Downloads

It suggested installing the 2.6.32 kernel branch.
So I did.
After having some problems we started doubting the versions, 6.18 says latest stable, but 6.32 is the default.
So I decided to download the 1.8 ISO and see what Proxmox serves at their new clients.
6.32 indeed.

Now I read on several places on this forum that openvz is not stable in this version.
Why does Proxmox delivers and advise a non stable kernel by default to its new users?

Different situations need different kernels. details are described here: http://pve.proxmox.com/wiki/Proxmox_VE_Kernel

Its simple. If you need stable OpenVZ, use 2.6.18.

But most new Proxmox VE users do not use OpenVZ, so 2.6.32 is best as default.

Hi Tom,

I'm really very suprised to hear that most new Proxmox users don't use OpenVZ.
Is everybody suddenly switching to Windows?
I can't imagine that Openvz has become so marginal that you choose to release a unstable version as default, but I probably (certainly) dont oversee everything.

Does this all mean that Proxmox will eventually drop Openvz?

Do you advise Proxmox ve 1.8 with the .18 kernel or should I stick to 1.5?

Thank you for your patience.

For what it is worth I didn't read carefully enough when I installed and am using mostly OpenVZ on a 2.6.32 cluster.

-One time a container remained locked after backup; but only once and it could have been the underlying storage that choked.
-If I migrate containers I have to restart the networking in them before their static DHCP lease renews or else I'll lose connectivity. Otherwise I just have to VNC in through the web interface and restart networking after the fact.

Other than that it has been fine so far. But as always YMMV

Hi Tom,

most are switching from the virtualization market leader, now also pushed due to their licensing changes for V 5.0 and yes, the majority of them is already running Windows. OpenVZ users does not switch for KVM, only some.

I can't imagine that Openvz has become so marginal that you choose to release a unstable version as default, but I probably (certainly) dont oversee everything.

We do not recommend 2.6.32 for OpenVZ now, this is wrong. As soon as the OpenVZ project got a stable release for 2.6.32 we also switch to this new stable.
We support and maintain currently 3 kernel branches so you as a user can choose which one is right for you.

Does this all mean that Proxmox will eventually drop Openvz?

All kernels works with 1.8, so just upgrade as always, see the Proxmox VE kernel page for the (simple) howto.

For the future releases, see our Roadmap.
