==General==
 
===What is a container, CT, VE, Virtual Private Server, VPS?===
 
:See [[Container and Full Virtualization]]
 
 
===What is a KVM guest (KVM VM)?===
 
:A KVM guest or KVM VM is a guest system running virtualized under Proxmox VE with KVM.
 
 
===What distribution is Proxmox VE based on?===
 
:Proxmox VE is based on [http://www.debian.org Debian GNU/Linux], Proxmox VE Kernel is based on RHEL6 Kernel with OpenVZ patches
 
 
==Installation and upgrade==
 
 
===Where can I find installation instructions?===
 
:See [[Installation]]
 
 
===Proxmox VE command line tools===
 
:See [[Command line tools]]
 
 
===How long will my Proxmox VE version be supported?===
 
According to [https://forum.proxmox.com/threads/version-end-of-life.22564/#post-113759 Wolfgang] Proxmox VE 3.4 is supported at least as long as the corresponding Debian Version is [https://wiki.debian.org/DebianOldStable oldstable]. Proxmox VE uses a rolling release model and the use of the latest stable version is always recommended.

==Hardware==
 
===CPU===
 
====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:
 
* Proxmox 2.0 on Squeeze [[Install Proxmox VE on Debian Squeeze on 32-Bit Processor]]
 
* Proxmox 1.4 on Lenny [[Install Proxmox VE on Debian Lenny on 32-Bit Processor]]
 
 
===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
 
 
====Intel====
 
64-bit processors with [http://en.wikipedia.org/wiki/Virtualization_Technology#Intel_virtualization_.28VT-x.29 Intel Virtualization Technology (Intel VT-x)] support
 
 
[http://ark.intel.com/search/advanced/?s=t&VTX=true&InstructionSet=64-bit List of processors with Intel VT and 64-bit]
 
 
====AMD====
 
64-bit processors with [http://en.wikipedia.org/wiki/Virtualization_Technology#AMD_virtualization_.28AMD-V.29 AMD Virtualization Technology (AMD-V)] support
 
 
==Networking==
 
 
===How do I configure bridged networking in an OpenVZ Ubuntu/Debian container?===
 
<ol>
 
<li>In the web gui under Virtual Machine configuration go to the network tab.
 
<li>Remove the ip address for venet and save. (Bridged Ethernet Devices will appear)
 
<li>SSH into your host system and enter the container you want set bridged networking for:
 
# vzctl enter <VMID>
 
<li>edit  /etc/network/interfaces using using the following format and save. (replace with settings for your network)
 
<pre>
 
auto lo
 
iface lo inet loopback
 
 
auto eth0
 
iface eth0 inet static
 
        address 10.0.0.17
 
        netmask 255.255.255.0
 
        network 10.0.0.0
 
        broadcast 10.0.0.255
 
        gateway 10.0.0.10
 
</pre>
 
<li>Shutdown the container.
 
<li>Go back to web gui and under "Bridged Ethernet Devices"  configure eth0 to vmbr0  and save. (a mac address will be automatically assigned)
 
<li>Start the container.
 
</ol>
 
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
 
<pre>
 
NETWORKING="yes"
 
#GATEWAYDEV="venet0"              # comment this and add line below
 
GATEWAYDEV="eth0"
 
HOSTNAME="hostname"    # should be set by proxmox
 
GATEWAY=123.123.123.123        # CHANGE (and remove from ifcfg-eth0)
 
</pre>
 
 
==Virtualization==
 
===Why do you recommend 32-bit guests over 64 bit guests?===
 
:64-bit guests makes sense only if you need greater than 4GB of memory.
 
:32-bit guests use less memory in certain situations, and are less resource intensive due to the shorter memory addressing scheme used.
 
::e.g. a standard installation of Apache2 on 64-bit containers consumes much more memory than on 32-bit installations.
