New Proxmox VE Kernels (2.6.18 - 2.6.24 - 2.6.32) [UPDATE]

Re: New Proxmox VE Kernels (2.6.18 - 2.6.24 - 2.6.32)

Hello,

will the 2.6.18 kernel syncronized with the openvz 2.6.18 kernel?

for about two weeks now there is the new 2.6.18 kernel around (164.11.1.el5.028stab068.3) which includes support for signalfd, which is needed for new guest systems like ubuntu karmic and lucid.

is this incorporated?

the latest openvz kernel does not work well with KVM, therefore its not released yet, as soon as this is solved we will publish it.

Hi Tom,

thank you for your answer, I have another question, are the proxmox kernels tickless and how is the High Resolution Timer set (1000hz?)?

thank you,

That depends on the kernel version.

That depends on the kernel version.

I am interested in the kernels 2.6.18 and 2.6.32 ....

I am interested in the kernels 2.6.18 and 2.6.32 ....

2.6.18 is

CONFIG_HZ_1000=y
CONFIG_HZ=1000

2.6.32 is
CONFIG_NO_HZ=y
CONFIG_HZ=100
CONFIG_HZ_100=y

Please take a look at the sources yourself instead of asking such question here.

Hi Dietmar,

Yes, you are right, i guess i was to lazy to look on the source,

Lazyness has a quality of it's own.

OpenVZ for 2.6.32 is here

Blog: http://community.livejournal.com/openvz/30998.html

Kernel: http://wiki.openvz.org/Download/kernel/2.6.32/2.6.32-afanasyev.1

Changelog: http://git.openvz.org/?p=linux-2.6.32-openvz;a=log;h=2.6.32-afanasyev

I hope, this can be a part of next Proxmox. With KSM it will be a killer feature.

any news on openvz@2.6.32 ?

 

[tom]

OpenVZ on 2.6.32 is highly experimental and brand new, so currently we do not integrate it as we need quite stable OpenVZ.

 

[mgiammarco]

Sorry to ask again, but any news about 2.6.32 and openvz?

Now debian has linux-image-2.6.32-openvz in unstable!

Thanks,
Mario

 

[tom]

we have a news page here, just read it and you got all our news...
(openvz is unstable in 2.6.32, that's the current situation)

hi
my question from a conservative sysadmin point of view: which is the supported and stable kernel for hosting KVM?

thank you

Hi,
i run two nodes in a cluster with 2.6.32 for kvm only since release of 1.5 without issues.
The nodes are 102 and 98 days up from now. For me look the 2.6.32 not unstable...

Re: New Proxmox VE Kernels (2.6.18 - 2.6.24 - 2.6.32)

yes. 2.6.32 is the way to go. as redhat6, ubuntu lucid and also squeeze already selected 2.6.32 you can expect a quite good maintained kernel branch.
if you install a new system, go for the kernel in the pvetest repository (with kvm 0.12.3). we plan to move this kernel to the stable repo soon - if you still need openvz on this host, go for the 2.6.24, also with kvm 0.12.3 (pvetest).

but be prepared, 2.6.24 will be end of support as soon as OpenVZ is stable for 2.6.32 -when? maybe next year. maybe with the release of Debian Squeeze, but who knows when Squeeze is stable, hopefully mid of year.

hi
ok so for KVM based solutions 2.6.32.

but when and where will we get the much needed support for cpuunits, ioprio and cpus in another openvz-kernel-branch - as I get it only 2.6.18 is supported here (though I have my doubts ioprio is working on non ovz-kernels).

thank you in advance

Re: New Proxmox VE Kernels (2.6.18 - 2.6.24 - 2.6.32)

yes. 2.6.32 is the way to go.

i'm using 2.6.18, as i have problems with live-migration using 2.6.32 (see thread: http://forum.proxmox.com/threads/3334)

if you install a new system, go for the kernel in the pvetest repository (with kvm 0.12.3). we plan to move this kernel to the stable repo soon

what are the differences to the current stable 2.6.32? was the issue above addressed? is there a changelog?

There is a hint in the OpenVZ bug tracker that they will implement this for 2.6.32 - but I do not know there schedule, hopefully soon.
