PVM Installation PVM Installation

This page explains PVM installation and related procedures.


Hardware Prerequisites

In order to install PVM operating system, at least one server is required. The following points should be considered regarding the hardware status of the server

1- CPU: the CPU type and model should support hardware-accelerated virtualization. Currently, all recently manufactured CPUs are equipped with this technology.

2- NIC: at least two network cards are required to run this version of PVM. It is better to use network cards with IG speed.

3- RAM: PVM operating system only needs 2 gigabytes of RAM. The required memory by virtual machines should be added to this value.

4- Hard: PVM operating system requires 30 gigabytes of free disk space. The required space by virtual machines should be added to this value. It is recommended to use:

-          Two separate partitions or RAID to install PVM and store the information of virtual machines.

-          A 10k hard drives for the operating system and at least a 15k hard drive for the virtual machines.


1. PVM Installation

In order to install PVM, you should first download the relevant ISO from download.pdnsoft.com/PVM and burn it on a CD. It is recommended to burn the CD with 16x speed.

Caution: if the server was not booted using the CD, after insuring the correct configuration Boot settings, use an external CD drive.

After the server boot, the installer window is displayed.

Select install or upgrade an existing system and press enter.

Caution: if the graphic card is not identified by the system, the installer interface runs in text mode.

After initial hardware checks, the system enters the partitioning section

In this section, several default methods can be used to partition the discs.

1-      Use All Space: selecting the first option means that the current partition information is removed and the system is partitioned again.

2-      Create Custom Layout: this option means manual or customized partitioning.


-          If you intend to decide about partitioning, check review.

-          in this case, the portioning page is opened and the partitions should be created manually


Fig.2: Different portioning methods


1.1. Automatic Partitioning

If you tend to install PVM fast and easy, you can select Use All space and delegate all portioning operations to the system. In this case, usually, three partitions, root, boot, and swap, are created and the major part of the disk space is dedicated to home.


-          In this case, the previous disk information is deleted and the disk is fully formatted.

-          It is better to select review, modify, and select home partition to change the mount point section from home to pvm.

-          In automatic partitioning, lvm is used to create partitions.

1.2. Advanced Partitioning

In order to perform advanced partitioning, you should select Create custom layout option. Before beginning to partition:

-          Remove all previous partitions from the disc.

-          Select the free space of the hard drive

-          Select the create option.

-          Select the standard partition option.

In the advanced partitioning, the following spaces are created to install PVM:

1-      Dedicating 500mb for /boot


Fig.4: Creating the boot partition



2-      Dedicating a space two times the RAM for the swap partition


We must note that this space is only used in special cases. Therefore, do not dedicate more than 32g. 


Fig.5: Creating the swap partition


3-      30gb is dedicated to /root


Fig.6: Creating the root partition


4-      in case you use a disc for installation, the rest of the disc is dedicated to /pvm and if a separate disc is used for the data, it is better to format and mount the entire disc in /pvm. select fill to maximum allowable size to dedicate the remaining space.

2. Installation

Pay attention that if more than one disc is identified by the system, you should select the considered disc for the installation. Selecting the considered disc and clicking on the corresponding icon shows the disc specification on the second column. At this point, this disc is selected for installation.

After partitioning, the installation process begins. Therefore, wait for the end of the programs installation


Fig.9: The beginning of installation


Press reboot after the installation process.

Do not forget to remove the PVM CD from the drive.

3. Initial PVM Boot


If the installation operations are successfully performed, the system boot is displayed as follows.

After 5 seconds, the booting process proceeds as follows.

4. PVM Configuration

After installing PVM, when the server is started for the first time, a wizard runs that guides you through the initial configuration

If you selected the exit option in the first stage, you can login with user name "setup" and password "pdnsoft" to run this wizard.


4.1. host/domain Configuration

In this stage, set the host and domain names. It is recommended to use a combination of the organization`s name and PVM to name the host.


Fig.13: Setting the host and domain names


Select Next to apply the setting and proceed to the next stage.


4.2. Time zone

Select the appropriate time zone from the list.


Fig.14: Setting the time zone

4.3. Network Cards

In this section, all the network cards identified by PVM are listed.

As it was mentioned, at least two network cards are required to run PVM. One of the network cards are used to connect the virtual machines` network to the internal network and the second card is used to manage the virtual machines.

At this stage, you should select the network cards that PVM uses for network communication of the virtual machines by pressing the space key.


At least one network card without the * sign should be located in the list. This network card is used to manage the virtual machines (PVM interface). The network configurations of the PVM management interface should be applied to this network card at the next stage.


Fig.15: The interfaces window


4.4. Configuration IP

In the interface window, select the considered network card using up and down arrow keys. We must recall that only the cards are displayed in the list that were not selected with the * sign in the previous stage.

In the Netmask window, you can insert a full ( or short (24) Netmask. Selecting Finish will apply and save the configurations.

5. Running the PVM service

After finishing the installation process, the login line is shown. Log in with username "setup" and password "pdnsoft". The PVM configuration window is shown. Go to the PVM menu.


Fig.17: PVM configuration menu


In this section, select the Start/Stop Service submenu and select Start. Now, a cluster with one node is ready, which you can connect to using PVM manager and create your first virtual machine. In order to run PVM manager, refer to the corresponding documents.
