Re: [Users] Question about Plesk support in VzLinux 8

[Maik Broemme]

Hi Kevim,

Actually we are already in initial talks with Plesk and discuss possible
options regarding Plesk support of Virtuozzo Linux 8 (VzLinux 8). It is
in an early stage and there is no defined timeline yet. It is a hot
topic and we are aware that control panel support is huge demand.

[Users] Question about Plesk support in VzLinux 8

[Kevin Drysdale]

Hello,

As per the subject really: are there any plans that you are aware of for 
Plesk (which I realise is now a separate company from yourselves, these 
days) to support VzLinux 8 ?  I can see it has support for VzLinux 7, but 
attempts to install it on 8 fail, and the Plesk support matrix does not 
list it as a supported distro at this time.


A great many of our existing customers run Plesk in their containers, so 
sadly unless/until VzLinux 8 has Plesk support (or Plesk has VzLinux 8 
support, whichever way around it goes), we would not really be able to use 
it as a migration target for our CentOS 8 customers.

Re: [Users] Question about libvirt and prlctl

[CoolCold]

Hello!
My logic and intuition says - it would be nice if that libvirt can handle
10% of modern openvz functions. I highly doubt it has support for anything
not in generalized list of VMs/VEs services - i.e. start/stop and may be
take snapshot.

[Users] Question about ploop snapshot + memory dump + inodes

[Devnull]

Hello!

Please forgive my bad English (greetings from France!).

I am working on an incremental backup tool called "openvz-diff-backups"
since two years (on my spare time so it does not progress fast).

Currently, I am switching to ploop format (test servers and more later).

The goal is to be able to restore backups to simfs or to ploop layout.

---

It works but I would like to hear from experts about this problem:

the backup tool is "file-based" and so, when restoring a backup, inodes
might/may/will change on target host.

One of the main goals about ploop was to preserve inodes but, with this
backup tool, I cannot ensure this.

With "cold backups" it does not really matter because we need to start
the container (however, some programs like "rkhunter" will complain).

But, when restoring "live backups" (ploop snapshot + memory dump), I
think this is more complicated.

---

So the question: is it really unsafe?

I mean, is there many programs/tools expecting inodes NOT to change
while they are running?

Best regards.

RE: [Users] Question About Debian Squeeze OVZ Kernel

[Martin Maurer]

Hi,

The OpenVZ squeeze kernel misses updates and some important features. If you 
run on Debian, you can just use our Proxmox VE kernels, they are based on the 
stable RHEL6 branch from the OpenVZ team.
See http://download.proxmox.com/debian/dists/ 

And you can also switch completely to Proxmox VE :-)

I think I'm going to dance around your questions some but hopefully answer them.

There are currently three stable OpenVZ kernel branches and they are all based 
on Red Hat Enterprise Linux kernels:  RHEL4 2.6.9, RHEL5 2.6.18, and RHEL6 
2.6.32.  Please note that Red Hat supports their kernels for 7 years and 
approximately every 6 months they have a new minor release for each major 
release that includes an updated kernel with backported drivers, bug and 
security fixes, and some new features.  Although a RHEL kernel is based on a 
specific mainline version, over their lifetime they get a lot of additional 
patches by Red Hat long after the mainline kernel developers and most everyone 
else has abandoned that version.  The longer the kernel has been out and the 
more releases it has had from Red Hat, the more divergent it is from the 
original/last mainline version.

Debian does not use RHEL-based kernels.  Why should they?  The kernel they have 
for Debian 6 is 2.6.32 but with various patches they have added to it.  
Mainline is still supporting 2.6.32 so I'm sure Debian (and Red Hat for that 
matter) pull in updates from mainline as they are made available.

The mainline 2.6.32 and the RHEL 2.6.32 kernels are a bit different but don't 
ask me to go into the technical specifics.  For one, I'm not knowledgeable 
enough about difference.

As you cans see the Debian and the RHEL6-based OpenVZ kernels differ such that 
a particular release from one can not be ahead or behind another measured in 
releases.  They are just different.  In fact the Debian 6 kernel lacks a few 
features that the RHEL6-based OpenVZ kernels have and vice versa.  For example, 
only the RHEL6-based OpenVZ kernel has vswap and cpulimits.  To the best of my 
knowledge, the Debian kernel does not.

They are just different.

Some recommend, including Kir the OpenVZ project lead (or so I've gathered) 
using the RHEL6-based kernel on Debian.  That takes a little work and doesn't 
really sound fun.  Many Debian users seem to be happy with the Debian provided 
kernels.  I myself recommend using RHEL or an EL clone for the host node 
(because of the kernel version parity and my own personal preferences) but I 
realize that isn't necessarily right for everyone.

It would be nice to have a wiki page that details all of the differences 
between the Debian and RHEL-based kernels but there are probably only a handful 
of people who know both well enough to really compare them... and they are 
changing / releasing fairly often.

Did I answer your questions?

[Users] Question About Debian Squeeze OVZ Kernel

[JR Richardson]

Hi All,

I'm in the lab testing debian squeeze and OVZ.  The current debian
repository is listing this for the OVZ kernel:

root@ovz-test:~# aptitude show linux-image-2.6.32-5-openvz-686
Package: linux-image-2.6.32-5-openvz-686
State: installed
Automatically installed: yes
Version: 2.6.32-38
Priority: optional
Section: kernel
Maintainer: Debian Kernel Team 
Uncompressed Size: 80.6 M

How does the debian kernel version  2.6.32-*[38]* coorespond to the
official OVZ release cycle kernels, the current stable release being
(vzkernel-2.6.32-042stab040.1.src.rpm )?

Does this indicate the debian kernel is 4 stable releases behind?  Is
anyone using the squeeze repository OVZ kernel?  Any feedback on
stability or use would be appriciated.

Thanks.

Re: [Users] Question About /proc file system in VMs.

I'm not quite sure what you want to do, but each CT has it's own virtual 
/proc. If you check for example the traffic of the veth/venet interface 
inside a CT you'll see only the information for the particular CT. Or 
you want to have a module showing information for all CTs?

Yes. It's possible. You can write file system as module, load it
from host (CT0) and mount your file system from CT.
And you can't do that, if you have access to CT only.

Yes. It's possible. You can write file system as module, load it from 
host (CT0) and mount your file system from CT.

And you can't do that, if you have access to CT only.

I don't know.  I guess it depends on if the kernel packages provided by the 
OpenVZ Project work for you out of the box... or if you need to compile your 
own like you have previously.  Give one of the stock ones a try and see if it 
works for you or not.  Since you haven't stated why you decided to compile your 
own... if it was needed for hardware support missing in a vendor kernel... or 
if you just wanted to... I don't have much info to go on.

Are you asking whether you can run OpenVZ on RHEL and CentOS? The answer 
is yes.

Are you asking whether you can run RHEL and CentOS inside OpenVZ 
containers? The answer is also yes to CentOS, and I don't know ahout RHEL.

How do you mean? You set up OpenVZ, then ran a Debian container, and 
tried to set up mail in Debian? I couldn't help you there, as I don't 
know Debian.

But I do run a dozen mail servers all under OpenVZ, and can say that 
OpenVZ does not cause any new problems for hosting email. If you can 
host a mail server on CentOS, then you can host it on CentOS inside OpenVZ.

I believe you are asking if OpenVZ works well on a Debian host node?  The 
answer to that is yes, as we have quite a few users using Debian and Ubuntu 
host nodes.  They do occasionally run into problems because the vast majority 
of them use kernels that are based on development branches of the OpenVZ kernel 
rather than stable branches.

If you also were asking if CentOS/RHEL is required to run OpenVZ?  The answer 
to that is no... although it does run quite well given the fact that the stable 
branches of the OpenVZ kernel are based on RHEL kernels.  That happens to be my 
preferred distro anyway (RHEL, CentOS and Fedora) so I don't have a problem 
with that.

If you are asking what runs well as a container?  The answer to that is all of 
the official OS Templates provided by the OpenVZ project and a large percentage 
of the contributed OS Templates.  I must admit that I mainly use CentOS and 
Fedora but in testing I haven't had any problems with Debian or Ubuntu 
containers.  I've had a user with a Gentoo container for a while who was very 
happy with it and now another user with an ArchLinux container who hasn't 
complained any.

I have seen a few people having problems with the network setup for the newest 
Ubuntu OS Template but I have been unable to duplicate that problem.

I do want to stress though that a lot of the experience one has relies on the 
OS Templates you use... and staying up-to-date with the OpenVZ kernel and user 
utilities.  I have seen users using ancient OS Templates provided by service 
providers that had problems.  I have seen users with older kernels and tools 
having problems.  If your packages are distro provided, rather than coming from 
the OpenVZ project, they are less likely to be current.  So, in that regard, 
since the OpenVZ Project runs official yum repos for RHEL/CentOS, RHEL/CentOS 
host nodes are more likely to be current.  I have heard complains about 
third-party repos and distro provided repos lagging behind... and people having 
problems.

I'm glad you are working now and the problem is behind you... so I'm guessing 
we won't have to dreg up the past... but if you want to we can.  You'll just 
have to provide a lot of details... for us to have any chance of being helpful.

I don't see any sense to make  cpuunits behave similarly to cpulimits, 
because this things for different purposes.
If you offer commercial VPS, with strict resource quota - cpulimit is 
for you.

For internal environment (all VPS is yours) cpuunits will better.

Hello, Scott. It's my understanding that it's not possible to achieve
a similar behaviour. _cpuunits_ only serves to indicate how to
distribute the cpu time between the competing containers. _cpulimits_
is a hard limit that will remain there no matter how much cpu time is
available.

For example, let's say that we define _cpulimits_ for a ct at 30%. If
that ct needs more cpu time than 30%, it doesn't matter if no other ct
is using the cpu. There's a limit there and it will be enforced. That
is to say, the ct will use 30% of the cpu time and the rest (70%) will
remain free (idle cpu).

If there were two cts, A and B, we could assign 30 _cpuunits_ to A and
70 _cpuunits_ to B. The result of that would be that when all the cpu
time is needed between the two cts, ct A is given 30% of the cpu time
and ct B is given 70% of the cpu time. However, as soon as ct B
doesn't need that much cpu time, ct A will be able to increase its
utilization beyond the 30% mark (using as much cpu time as it needs,
provided ct B is not needing it). In other words, _cpuunits_ can work
as _cpulimits_ only in those situations when the cpu time needed is
equal or greater than the available cpu time.

Cheers,

cpulimit is a hard quota of resources.
If you set for example

vzctl set 101 --cpulimit 50 --save

your VE will not use more than 50% of cpu.


cpuunits is relative limitation.
cpuunits allows your VE to use all processor time in case if 
processor(s) in idle state.

Also it allows to specify the ratio of processor usage between VEs.

Hi Amba,

ok, i've supposed that, the error occured while a non-OpenVZ kernel is 
booted:


ubunutu shipped a kernel version 2.6.22-... and the (stable) OpenVZ 
Kernel at debian.systs.org is a 2.6.18, so the first kernel to boot is 
the 2.6.22 and than the "older" 2.6.18 OpenVZ kernel.


So please inspect your boot loader config, eg. grub (-> edit 
/boot/grub/menu.list ) and place the openvz kernel on first boot order 
and reboot the machine.


and voila another OpenVZ node is on the way :-)

 Thorsten

Thanks for your answer.  I am now running into the following problem:

At the step:
#sudo wget http://debian.systs.org/dso_archiv_signing_key.asc -q -O - |
apt-key add -

gpg: no writable keyring found: eof

Re: [Users] Question on openvz install on ubuntu

[Kir Kolyshkin]

I guess that Ubuntu 7.10 corresponds to Debian Etch, so you are using 
the wrong part of the instruction.


You should look at
http://wiki.openvz.org/Installation_on_Debian#precompiled_kernel_images_at_debian.systs.org

And yes, the page is organized badly, I would suggest moving "building 
your own kernel in a debian way" to a separate article, and maybe even 
provide separate articles for Sarge and Etch. Can somebody work on it?

debian.systs.org doesn't have the 2.6.9 kernels anymore.
Try ovzkernel-2.6.18.

[Users] Question about veth interfaces

[Nathan Broderick]

Hi,

I have an installed system of OpenVZ and it works very well.  One 
question that I have is when we stop and start the veth interfaces 
(ifdown veth0; ifup veth0;) all the accounts on the system no longer 
will accept ssh incoming connections.  It almost seems like the routing 
on the accounts get changed.  Is there a better way to bring down and up 
the interfaces in case there is a problem?
