Thanks for the new 2.6.24 kernel I'm going to try it out and see how it works. Maybe others can join this thread and report on their experiences.

Binary RPM works fine for me. However I encountered the following problems while compiling OpenVZ 2.6.24 kernel from sources:
1) config that is provided at wiki.openvz.org is definitely not appropriate for sources - Kconfig system still asks a lot of questions.
2) CONFIG_SIM_FS is missing in Kconfig file, so it's impossible to compile simfs without editing Kconfig manually.
3) Compilation fails:
/home/vass/linux-2.6.24-openvz/include/linux/freezer.h:72: undefined reference to `refrigerator'
/home/vass/linux-2.6.24-openvz/include/linux/freezer.h:72: undefined reference to `refrigerator'

Switching CONFIG_VZ_CHECKPOINT off helps to continue compilation.
4) OpenVZ related warnings while compilation:

configs from http://wiki.openvz.org/Download_kernel_2.6.24
were used.

In fact kernel-2.6.24-ovz002.2.src.rpm contains them.

I have compiled 2.6.24 + the OpenVZ patches for a non-production server running Debian Etch and haven't had any major issues as of yet.

I wasn't able to access my virtual environments via network from outside of the host node until I added this to my /etc/sysctl.conf:

net.ipv4.conf.all.forwarding=1

It seems that setting net.ipv4.conf.default.forwarding=1 is not enough for this kernel version, although this worked for my previous 2.6.18 based kernel.

For what it's worth I'm running it on 2 of my servers and it's working for me. I'm waiting a little while just to see if a new version gets posted to fix new problems.

No, I've just patched openvz kernel sources from gentoo portage. Could you please fix the link, it has internal IP. Thanks.

EDIT: nevermind, cloning from git.
EDIT2: compiled, will try tomorrow, thanks.

Hi,

let's share experience with OpenVZ 2.6.24:

I've taken the kernel-source from git http://git.openvz.org/?p=linux-2.6.24-openvz;a=summary
and kernel config from http://download.openvz.org/kernel/branches/2.6.24/2.6.24-ovz 002.2/configs/kernel-2.6.24-i686.config.ovz and built that kernel on a Debian Stable 4.0 aka etch:

* CT/VE checkpointing and restore works
* add/del IPv4 IP works, IPv6 cann't be used in CT/VE at the moment
* some kernel errors/failing occurs, will be described at bugszilla.

For testing only, a debian gpg-signed git(ty) repository can be found at:

# http://debian.systs.org/debian gitty openvz

Please post output from this script in VE0 after fresh boot
on .18 and .24 kernels:

for i in $(ls /proc/sys/net/ipv4/conf/*/forwarding); do
echo $i
cat $i
done

and in VE too, just in case. Does Etch runs sysctl
init script before starting netdevices in both cases?

Regardless, relying on "default" is not wise, because
you're on mercy of init scripts ordering.
I'd suggest net.ipv4.conf.all.forwarding=1 or
net.ipv4.ip_forward=1.

I've managed to boot openvz .24 kernel (current git), no kernel panic at this time, but I have a problem. Neither server, nor people behind the nat cannot connect to remote ftp servers. Also I had to copy /dev/* to VE and set static devices in config. VE (gentoo template) udev doesn't create anything.

I downloaded and installed the kernel on a fresh install of Fedora 8. (running i686 on Pentium 4 with 512 MB ram)
Everything seemed to work until I wanted to look at the DRBD module. There is none. Are we not supporting DRBD for this kernel?

Below is a patch which ups the DRBD version included in the 2.6.24-ovz002.2 patch to 8.0.11, which compiles for me. Apply this patch over 2.6.24-ovz002.2.

http://202.8.254.24/patch-ovz002.2-drbd-upgradeto-8.0.11.bz2

According to drbd changelog:

8.0.9 (api:86/proto:86)
...
38 * Made it to compile on Linux-2.6.24.

Which brings me to the question.. Are there any openvz mods for drbd? I'm not sure, someone clue me in..

Current git version doesn't contain drbd at all. So patch is useless for it.

Thanks for the info! I think that I will have to back down to kernel-2.6.18 until I can give this more time.

We need a server distro that incorporates the patches and modules to support OpenVZ and DRBD! When I start working 42 hour days....
