OpenVZ kernel - production ready?

[xkuba]

Hi,

I'm little bit confused regarding available OpenVZ kernels.

Could someone clarify it for me, please?

openvz.org - "the only stable kernel is 2.6.18, nothing else should be used in production"

debian stable - 2.6.26-openvz

proxmox - 2.6.24-openvz

So, which ones are considered production ready? What are the differences between them, how they relate to each other?

Thank you,

Kuba

2.6.9 and 2.6.18 are stable and maintained from the openvz team. 2.6.24, 2.6.26 and 2.6.27 is not marked as stable on their project site and in fact they stopped the development of these branches (more or less). I assume the openvz teams waits till its clear what kernel is used for RHEL6 and then they will try to make a new stable openvz for this (2.6.31 or higher, but nothing fixed).

you need to know that the openvz team only mark kernels for stable suited for their commercial product, virtuozzo. only for these they do the extensive testing.

Debian team maintains 2.6.26, widely used in production and we at Proxmox tries to do our best in our 2.6.24 kernel, also widely used in production systems.

Hi Tom,

thank you for your answer, I really appriciate that Proxmox team members are active in the forum!

One more dumb question: Why don't you build your openvz+kvm kernel on top of either openvz 2.6.18 or debian 2.6.26? Why do you maintain your own version? What are the main differences? Wouldn't it be easier?

Just curious

Thank you,

We do not maintain our own version - instead we use

http://git.openvz.org/?p=ubuntu-hardy-openvz;a=summary

The OpenVZ team claimed to support this branch (it is also used by ubuntu).
