Proxmox VE ver 1.7 with kernel 2.6.32…Virtualization…

January 14, 2011

Proxmox Virtual Environment is an easy to use Open Source virtualization platform for running Virtual Appliances and Virtual Machines. Proxmox VE is an open source project, developed and maintained by Proxmox Server Solutions GmBH. Proxmox can be considered the same as VMWARE player , VMWARE Esxi , Virtual Box , Xen Hypervisor and some other virtualization product. Anybody who have some experience using these  virtualization software will have no problem installing , setup and using Proxmox VE.

Proxmox VE is based on Linux operating system , that is Debian Linux GNU distribution. You have to download the iso image file , burn it to a cd or you can use it in VMware player. Just boot the distribution up , and install the operating system . The  installation is based on web based configuration management. The software is intended to be used for dedicated server , and it uses solid  linux kernel.

System requirements Proxmox VE


  • Dual Socket, Quad Core CPU
  • CPU: 64bit (Intel EMT64 or AMD64), Multi core CPU recommended
  • Intel VT/AMD-V capable CPU/Mainboard (for KVM Full Virtualization support)
  • 8 GB RAM is good, more is better (grab as much as possible)
  • Hardware RAID with batteries protected write cache (BBU)
  • Fast hard drives, best results with 15k rpm SAS, Raid10
  • Two Gbit NIC (for bonding), additional NIC´s depending on the preferred storage technology
Minimum (for testing)
  • CPU: 64bit (Intel EMT64 or AMD64)
  • Intel VT/AMD-V capable CPU/Mainboard (for KVM Full Virtualization support)
  • Minimum 1 GB RAM
  • Hard drive
  • One NIC
Supported storage technologies (NAS/SAN)

The following standard technologies are supported.

  • Local storage (mandatory)
  • iSCSI
  • FC
  • NFS

Proxmox VE Cluster enables central management of multiple physical servers. A Proxmox VE Cluster consists of one master and several nodes (minimum is a master and one node).

Main features

  • Centralized web management
  • One login and password for accessing all nodes and guests
  • Console view to all Virtual Machines
  • Migration of Virtual Machines between physical hosts
  • Synchronized Virtual Appliance template store

Create a Proxmox VE Cluster

First, install two Proxmox VE servers, see Installation. Make sure that each Proxmox VE server has a unique host name, by default all server has the same host name.

Currently the cluster creation has to be done on the console, you can login to the Proxmox VE server via ssh.

All settings can be done via “pveca”, the PVE Cluster Administration Toolkit

USAGE: pveca -l             # show cluster status
       pveca -c             # create new cluster with localhost as master
       pveca -s [-h IP]     # sync cluster configuration from master (or IP)
       pveca -d ID          # delete a node
       pveca -a [-h IP]     # add new node to cluster
       pveca -m             # force local node to become master

Define the master

Login via ssh to the first Proxmox VE server.

Create the master:

pveca -c

To check the state of cluster:

pveca -l

Add a node to an existing master

Login via ssh to a second Proxmox VE server. Please note, the node should not have any VM´s. (If yes you will get conflicts with identical VMID´s – to workaround, use vzdump to backup and to restore to a different VMID after the cluster configuration).

Join a node to the master:


To check the state of cluster:

pveca -l

Display the state of cluster:

pveca -l
 1 :   M     A    5 days 01:43   0.54    20%     1%     4%
 2 :   N     A    2 days 05:02   0.04    26%     5%    29%
 3 :   N     A           00:13   1.41    22%     3%    15%
 4 :   N     A           00:05   0.54    17%     3%     3%

Now, you can start creating Virtual Machines on Cluster nodes by using the
Central Web Based Management on the master.

Well , that’s all for this week post. Hope to see you guys again next week with more IT techie stuff , computer news , and much more…
