4. Who Is Who A Brief Introduction Thomas Lamprecht Studying Computer Engineering at Vienna’s Institute of Technology Interested in Linux and open source since a young age Started working on Proxmox VE at beginning of summer Proxmox Self-funded open source start-up based in Vienna/Austria Proxmox Mail Gateway Proxmox Virtual Environment release Very active and helpful Community World Wide partner Network Thomas Lamprecht — Proxmox Virtual Environment 4.0 3/23

5. What Proxmox VE Is A Brief Introduction Open source (AGPLv3) server virtualization solution Multilingual GUI to manage VMs and CTs Based on Debian Using: KVM/QEMU for full virtualization LXC for container based systems A wide variety of storage technologies In house developed High Availability manager corosync for fault tolerant cluster communication Contributions from all over the world Thomas Lamprecht — Proxmox Virtual Environment 4.0 4/23

8. KVM Fast 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 Thomas Lamprecht — Proxmox Virtual Environment 4.0 7/23

9. LXC Lightweight Linux Container Performs like a standalone server No emulation, runs as process on the host Provide and secure system containers through: Control groups (cgroups) Namespaces Mandatory access control seccomp AppArmor Limited to Linux guests only Thomas Lamprecht — Proxmox Virtual Environment 4.0 8/23

12. Proxmox VE 4.0 What Is New Replacing OpenVZ with LXC Linux Kernel 4.2 New High Availability manager QEMU 2.4 IPv6 support AppArmor Integrated Ceph server DRBD9 support Advanced bash auto completion Thomas Lamprecht — Proxmox Virtual Environment 4.0 11/23

22. Proxmox VE Cluster Clustering Thomas Lamprecht — Proxmox Virtual Environment 4.0 13/23

23. Proxmox VE Cluster Control 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 Thomas Lamprecht — Proxmox Virtual Environment 4.0 14/23

24. Proxmox VE Cluster Create a Cluster First create the cluster on one node: [ uno]# pvecm c r e a t e sfs −c l u s t e r Then add other nodes to it: [ due]# pvecm add <ip−from−uno> [ t r e ]# pvecm add <ip−from−uno−or−due> A three node cluster, ready for High Availability, is now conﬁgured. Thomas Lamprecht — Proxmox Virtual Environment 4.0 15/23

25. High Availability Securing the Cluster Service What is HA? Watchdog based self-fencing Monitor Virtual Machines and Container Focused on simplicity and stability Thomas Lamprecht — Proxmox Virtual Environment 4.0 16/23

26. High Availability Adding 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 s quorum OK master due ( active , F r i Nov 6 15:11:00) lrm due ( active , F r i Nov 6 15:11:02) lrm t r e ( active , F r i Nov 6 15:11:02) lrm uno ( active , F r i Nov 6 15:11:02) s e r v i c e vm:100 ( tre , s t a r t e d ) Thomas Lamprecht — Proxmox Virtual Environment 4.0 17/23

29. pmxcfs The Proxmox Cluster Filesystem Realtime replicated Database-driven Simple conﬁguration ﬁles Strong consistency checks Fault tolerant Thomas Lamprecht — Proxmox Virtual Environment 4.0 19/23

30. Proxmox VE API REST- and powerful Formally deﬁned with JSON schema Automatic parameter veriﬁcation Automatic generation of API documentation Provides easy CLI tools generation Thomas Lamprecht — Proxmox Virtual Environment 4.0 20/23
