Will Proxmox VE run on a 32bit processor?

Proxmox VE works only on 64-bit CPU´s (AMD or Intel). There is no plan for 32-bit for the platform.

There are, however, unofficial (and unsupported) instructions for manually installing Proxmox on 32-bit systems:

Supported CPU chips

To check if your CPU is virtualization compatible, check for the "vmx" or "svm" tag in this command output:

egrep '(vmx|svm)' /proc/cpuinfo

How do I configure bridged networking in an OpenVZ Ubuntu/Debian container?

  1. In the web gui under Virtual Machine configuration go to the network tab.
  2. Remove the ip address for venet and save. (Bridged Ethernet Devices will appear)
  3. SSH into your host system and enter the container you want set bridged networking for: # vzctl enter <VMID>
  4. edit /etc/network/interfaces using using the following format and save. (replace with settings for your network)
     auto lo
     iface lo inet loopback
     auto eth0
     iface eth0 inet static
  5. Shutdown the container.
  6. Go back to web gui and under "Bridged Ethernet Devices" configure eth0 to vmbr0 and save. (a mac address will be automatically assigned)
  7. Start the container.

Finally check that networking is working by entering the guest and viewing the results of ifconfig

  • In a Centos/RHEL container, check the gateway device is set correctly.

edit /etc/sysconfig/network

#GATEWAYDEV="venet0"              # comment this and add line below
HOSTNAME="hostname"    # should be set by proxmox
GATEWAY=         # CHANGE (and remove from ifcfg-eth0)


Why do you recommend 32-bit guests over 64 bit guests?

64-bit makes sense only if you need greater than 4GB of memory.
32-bit guests use less memory in certain situations
e.g. a standard installation of apache2 on 64 bit containers consumes much more memory than on 32 bit.
