Installing proxmox on debian wheezy

I’ve heard about this system of virtualization earlier (…

This is a system using KVM and OpenVZ as hypervisors and having a convenient web interface for management. So, we have a pumped-up home computer with Debian Wheezy 7.3 (amd64) on board. When I finally decided to install it, it turned out that now, with the release of the new version of Proxmox 3.1, the policy of granting access to repositories has changed.

Here ( we can find descriptions of the repositories. I see that Proxmox VE Enterprise Repository is not suitable – it’s paid subscription.

Official guide ( strongly recommends Proxmox VE No-Subscription Repository, but description of this repository scares me: “The pve-no-subscription repo can be used for testing and non-production use. Its not recommended to run on production servers as these packages are not always heavily tested and validated. As the name suggests, there is no Proxmox VE Subscription Key needed to access this repository.

What to do? I decided to try to put version 3.0 – a stable previous release.

Add a line to the package manager:

echo "deb wheezy pve" >> /etc/apt/sources.list

Further, we will do, as described in the documentation. Put the repository key:

wget -O- "" | apt-key add -

Then update packages list and install currently available updates (I’m using aptitude):

aptitude update && aptitude safe-upgrade

Install kernel:

aptitude install pve-firmware pve-kernel-2.6.32-26-pve

At the same time, the system shown error message::

The following packages have unsatisfied dependencies:
 pve-firmware : Conflicts: firmware-linux-free but 3.2 installed
                Conflicts: firmware-linux-free:i386 which is a virtual package.
                Conflicts: firmware-realtek but 0.36+wheezy.1 installed
                Conflicts: firmware-realtek:i386 which is a virtual package.
The following actions will allow dependencies:

     Remove next packages:                                          
1)     firmware-linux-free                                              
2)     firmware-realtek                                                 

     Leave the following dependencies unresolved:                     
3)     linux-image-3.2.0-4-amd64 recommends firmware-linux-free (>= 3~)

Will you accept this decision? [Y/n/q/?]

I took this decision, so proxmox developers propose to remove the kernel linux-image-3.2.0-4-amd64
After checking after rebooting, that everything works with kernel pve-kernel-2.6.32-26-pve, safely delete the default kernel:

aptitude remove linux-image-amd64 linux-image-3.2.0-4-amd64

We check the bootloader configuration:


Now we install Proxmox VE packages:

aptitude install proxmox-ve-2.6.32 ntp ssh lvm2 postfix ksm-control-daemon vzprocps open-iscsi bootlogd

Enter https://your-hostname:8006/ and rejoice!

Errors when installing Proxmox on Debian

[1] Proxmox: initscript rrdcached, action “start” failed

The installation of proxmox-ve-2.6.32 and its dependencies was interrupted by a specific error:

Configures package rrdcached (1.4.7-2) …
Starting RRDtool data caching daemon: rrdcachedBase directory (-b) resolved via file system links!
Please consult rrdcached '-b' documentation!
Consider specifying the real directory (/media/all/var/lib/rrdcached/db)
invoke-rc.d: initscript rrdcached, action "start" failed.
dpkg: Error while processing parameter rrdcached (--configure):
 Subprocess installed post-installation script returned error code 5
dpkg: Dependencies do not allow to configure package pve-cluster:
 pve-cluster depends on rrdcached, hovewer:
  Package rrdcached not yet configured.

This was due to the fact that I made /var directory as symbolic link from the directory located on same hard drive, while the root of the system is on the SSD. I could, of course, mount it, but I was too lazy to create a separate partition for /var, so I used the same partition as /home. You should not have such a problem.

Overcame it so:

1) Determine where the configuration is stored

dpkg -L rrdcached


2) Open file and uncomment the parameter, specifying folder actual location without symbolic links:

nano /etc/default/rrdcached

OPTS="-b /media/all/var/lib/rrdcached/db"

[2] Proxmox: Unable to get local IP address

Configures package pve-cluster (3.0-8) …
[....] Starting pve cluster filesystem : pve-cluster[main] crit: Unable to get local IP address
invoke-rc.d: initscript pve-cluster, action "start" failed.

How I overcame it (rocknroothost -this is my hostname, substitute it with your one here):

cp -av /etc/hosts /etc/hosts.original

Then we edit /etc/hosts for next view:

--- localhost.localdomain localhost rocknroothost pvelocalhost

Also /etc/hostname for such view:


after that we need execute:

apt-get install -f

And installation process will continue

/etc/init.d/ start

[3] Proxmox: failed to load

Finally, having worn out the installation, I enter the browser:
http://rocknroothost:8006/ => get error: failed to load, and I check service

lsof -i tcp:8006

I break my head, google … but it’s just ridiculous – I had to watch carefully:
https , no http 🙂

Delete the message proxmox “No Valid Subscription”

How to we can remove proxmox message “No Valid Subscription”?

To do this, you just need to edit the file pvemanagerlib.js:

open in test editor:

nano /usr/share/pve-manager/ext4/pvemanagerlib.js

You can use “locate pvemanagerlib.js” command to find this file.

Find the line:

  if (data.status !== 'Active') {

We copy and comment on it (just in case) and correct, as shown below:

//  if (data.status !== 'Active') {
  if (false) {

Now “No Valid Subscription” message does not bother us anymore.

Update. path in new proxmox version: /usr/share/pve-manager/js/pvemanagerlib.js

Problem with java plugin in proxmox

The java plugin installed in this way works well by itself, but in the case of proxmox, it produces an error:

Appication Blocked by Security Settings: Your security setting have blocked a self-signed application from running

Here is error screenshot:


What to do? There are 2 solutions:

[Solution 1] Install IcedTea plugin and then connect it to the browser

aptitude install icedtea-7-plugin

And so on … But I did not do it, because I found a better solution -> next “Solution 2”.

[Solution 2] Configure Java Control Panel


Execute this command in the terminal and you get run the Java Control Panel.
If in your case there is no such file, then you can find it like this:

find /usr/lib/jvm/ | grep -i ControlPanel

Next, choose Security > Edit Site List > Add And add your path to the host (it was https://aspetruk:8006 in my case)


After that, proxmox console worked perfectly.
