Also, regarding the license. If you’ve been checking it with “vzlicview” – that’s wrong approach. By the moment you’ve been installing the trial license there was just “virtuozzo linux”, not “virtuozzo 7” product – it just couldn’t install the trial license for virtuozzo itself. It installs trial subscription for readykernel.

Subscription license is checked via:
# vzsubscribe info

Hi,


I was now able to reproduce and document the steps needed to go from CentOS 7 -> Virtuozzo Linux 7 -> Virtuozzo 7.

You need to install CentOS 7 your prefered way with /vz ext4 partition (I made all partions ext4, as the Virtuozzo 7 Bare Metal installer does).

First the steps to convert CentOS 7 (minimal) to Virtuozzo Linux 7 with vzdeploy:

cd /root

yum install wget

wget http://repo.virtuozzo.com/vzlinux/vzdeploy/vzdeploy

chmod 700 vzdeploy

./vzdeploy

This takes some time and finishes without interaction needed. At the end you'll see:

-----
Complete!
Installing a trial license...
Start activation for code trial...
License VZLINUX [*****] was loaded successfully.
Calling 0
sh: 0: command not found
Subscription completed unsuccessfully
Activation completed successfully with product key *****
You can find complete log in /var/log/vzdeploy.log
-----

Pavel told me that this licence is only needed for some features, that are only available in the commercial version. As far as I can see, the licence is no longer installed after conversion to Virtuozzo 7 is done.

The next step is adding the Virtuozzo 7 repositories to yum. Note that the factory repository is enabled for my test, but with lower priority than the release repository. I need to check what have been the original settings of the bare metal installer before setting up a production system.

We now fetch the lists of the available packages:

yum update

That will import the required GPG key, you have to allow it, when seeing this message:

As Pavel said (thank you very much for the hint) we can use yum groups to install all required packages:

yum grouplist | grep -i virtuozzo

returns in my case:

  Virtuozzo
  Virtuozzo Containers
  Virtuozzo Hypervisor

Then install the groups

yum groupinstall 'Virtuozzo' 'Virtuozzo Containers' 'Virtuozzo Hypervisor'

Finally reboot to run Virtuozzo 7.

Hello,

Good call, Volker!
To my shame I was not aware of vzdeploy script, which, as it seems, was completed just a week ago or so. Taking in account existence of "vzdeploy" - it should be possible.

In case anyone searches for the script, it can be obtained here:
http://repo.virtuozzo.com/vzlinux/vzdeploy/vzdeploy

Jurijs,
Regarding the packages installation - I believe you may try installing Virtuozzo  using "yum groups":
# yum grouplist | grep -i virtuozzo
  Virtuozzo
  Virtuozzo Containers
  Virtuozzo High Availability
  Virtuozzo Hypervisor
  Virtuozzo Storage
  etc...

Note, first you must replace centos packages with virtuozzolinux packages.

That should be better than cherry-picking packages from the repository.
I'd recommend installing at least "Virtuozzo", "Virtuozzo Containers" and "Virtuozzo Hypervisor", "QEMU".
Note, I've composed the list by briefly checking all available groups, it might be incomplete. And I haven't tested this either.

Volker, if you can add anything - please do.

Best Regards,

Hi,

I did one try so far this way:

1) Install CentOS7
2) Use vzdeploy to convert CentOS7 to Virtuozzo Linux 7
3) Install yum repo for Virtuozzo 7 (extracted from VZ7 bare metal installer inside of a KVM)
4) Install packages needed for Virtuozzo 7
5) Reboot into Virtuozzo 7

I have found at least one error in my notes, I need to retry the steps in my test KVM. When I have reproducable steps, I plan to publish them. I was unable to use the bare metal installer, too.


Regards
  Volker

Hi All,

I tried to google, but unsuccessfully. :)

Is there any possibility to install OpenVZ / Virtuozzo 7 via yum without USB or CD, like OpenVZ 6?

Thank you!

Jurijs
