2. Open source virtualization platforms 3. KVM Main developer: RedHat Kernel integration state: in kernel since 2007 Status: production ready Hardware support: same as Linux Virtualization type: full virtualization Supported client OS: Linux, FreeBSD, Windows 4. KVM architecture 5. Xen Main developer: Citrix, XenSource Kernel integration state: partially in kernel since 2012 (client), no plans about the server Status: production ready Hardware support: only fixed number of hardware, see HCL Virtualization type: full virtualization, paravirtualization Supported client OS: Linux, FreeBSD, Windows 6. Xen architecture 7. OpenVZ Main developer: Parallels (ex. SwSoft) Kernel integration state: partially in kernel and work in progress Status: production ready Hardware support: same as Linux Virtualization type: os level virtualization, containerization Supported client OS: Linux 8. OpenVZ architecture 9. LinuX Containers, LXC Main developer: same as kernel (Intel, IBM, Parallels) Kernel integration state: partially in kernel and work in progress Status: not ready for production (issues in network, disk) Hardware support: same as Linux Virtualization type: os level virtualization, containerization Supported client OS: Linux 10. LinuX Containers, LXC architecture 11. Why OpenVZ? Production ready since 2006 Extremely low overhead (in compare with Xen/KVM is about 20%) Simple integration into Linux stack Many successful projects (LXC): Heorku, CloudLinux, Docker (dot.cloud) 12. KVM vs OpenVZ vs Xen LAMP 13. KVM vs OpenVZ vs Xen Web App 14. OpenVZ customers 15. OpenVZ requirements Almost any physical server (yes, you can use old notebook) Operation system: CentOS 6, RHEL 6 or Scientific Linux 6 One external or internal IP address Internet connection (only for downloading packages and templates) One hour of free time 16. OpenVZ, server resources Server resources: RAM HDD CPU Network 17. OpenVZ deployment echo "SELINUX=disabled" > /etc/sysconfig/selinux wget -P /etc/yum.repos.d/ http://ftp.openvz.org/openvz.repo yum install -y vzkernel yum install -y vzctl vzquota ploop shutdown r now yum remove kernel -y 18.
