  • I'm not sure because OpenVZ is function limited environment for some applications which needs custom kernel modules or kernels.

  • I'm really interested in this. I've had a cheap OpenVZ host for awhile. The only problem I have with it is I am having trouble enabling SElinux. I recently bought a KVM package for a lot more money from the same company. I've had nothing but problems with it. I am trying to work with OwnCloud and Drupal ELMSLN. I am going to see if the company will exchange the KVM for a OpenVZ Pure SSD VPS. Do you think this is the right way for me to go?

    Containers are the future of the Cloud Containers are the future of the Cloud Presentation Transcript

    • Containers are the future of Cloud Pavel Odintsov CTO, FastVPS Eesti OU odintsov@fastvps.ee
    • Open source virtualization platforms
    • 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
    • KVM architecture
    • 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
    • Xen architecture
    • 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
    • OpenVZ architecture
    • 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
    • LinuX Containers, LXC architecture
    • 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)
    • KVM vs OpenVZ vs Xen LAMP
    • KVM vs OpenVZ vs Xen Web App
    • OpenVZ customers
    • 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 
    • OpenVZ, server resources Server resources: • RAM • HDD • CPU • Network
    • 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
    • OpenVZ – container creating vzctl create 101 --ostemplate debian-6.0-x86_64 --layout ploop --ipadd 88.198.144.251 --hostname mytesthostname.ru --config vswap-2g --diskspace 10G vzctl set 101 --onboot yes --ram 4G --swap 1G -- diskspace 20G --save vzctl start 101 vzctl set 101 --userpasswd root:openvz_2013
    • OpenVZ – additional tools • vzctl destroy – remove container with all data • vzctl stop – container stop • vzlist –a – list of all available containers on host
    • OpenVZ information • http://openvz.org • http://twitter.com/_openvz_ • http://bugzilla.openvz.org • http://openvz.livejournal.com • http://git.openvz.org
    • Thank you! :) Pavel Odintsov CTO, FastVPS Eesti OU odintsov@fastvps.ee
