KVMFast Full Virtualization

Leading virtualization technology for Linux

In mainline kernel since 2.6.20

Arbitrary guest support (Linux, Windows, BSD, . . . )

Paravirtualization (VirtIO)

Live migration to other hosts


LXCLightweight Linux Container

Performs like a standalone serverNo emulation, runs as process on the hostProvide and secure system containers through:

Control groups (cgroups)NamespacesMandatory access controlseccompAppArmor

Limited to Linux guests only

Proxmox VE ClusterClustering


Proxmox VE ClusterControl the Cluster

Use the Web GUI and the CLI tools

Access the whole cluster on every node

Unique multi-master design

No single point of failure


Proxmox VE ClusterCreate a Cluster

First create the cluster on one node:

[ uno]# pvecm c r e a t e s f s −c l u s t e r

Then add other nodes to it:

[ due]# pvecm add <i p−from−uno>[ t r e ]# pvecm add <i p−from−uno−or−due>

A three node cluster, ready for High Availability, is nowconfigured.


High AvailabilitySecuring the Cluster Service

What is HA?

Watchdog based self-fencing

Monitor Virtual Machines and Container

Focused on simplicity and stability


High AvailabilityAdding Services

Add a CT or a VM to the Proxmox VE HA manager

[ uno]# ha−manager add 100

Now the services are HA monitored.

[ uno]# ha−manager s t a t u squorum OKmaster due ( a c t i v e , F r i Nov 6 1 5 : 1 1 : 0 0 )l rm due ( a c t i v e , F r i Nov 6 1 5 : 1 1 : 0 2 )l rm t r e ( a c t i v e , F r i Nov 6 1 5 : 1 1 : 0 2 )l rm uno ( a c t i v e , F r i Nov 6 1 5 : 1 1 : 0 2 )s e r v i c e vm: 1 0 0 ( t r e , s t a r t e d )
