History

Here we list major project milestones.

1999

Kir Kolyshkin wrote: Indeed it was 1999 when our engineers started adding bits and pieces of containers technology to Linux kernel 2.2. Well, not exactly "containers", but rather "virtual environments" at that time -- as it often happens with new technologies, the terminology was different (the term "container" was coined by Sun only five years later, in 2004).

2000

• Nov, 2000 - Limited beta testing -- we were providing free VEs to people to run their stuff at. I remember we had to modify EULA to disallow all kinds of abuses, such as bots and CPU hoggers.

2002

• Jan, 2002 - SWsoft (now known as Odin) initially released a product for Linux named Virtuozzo. Their current product is named Virtuozzo. It was Virtuozzo 2.0, press release went out 10 Jan 2002.

2005

• Virtuozzo for Microsoft Windows was released
• SWsoft created the OpenVZ Project to release under a GPLv2 license the underlying technology upon which Virtuozzo builds

2006

• 4 Aug, 2006 - Debian Linux Adopts OpenVZ Virtualization Software
• 16 Aug, 2006 - OpenVZ for RHEL4
• Oct, 2006 - OpenVZ ported to SPARC and PPC. PPC and SPARC support were announced on LWN.net.
• Nov, 2006 - OpenVZ adds live migration capability

2007

• 13 Mar, 2007 - OpenVZ software for Red Hat Enterprise Linux 5

2008

• 17 Apr, 2008 - 2.6.25 is out
• Oct, 2008 - OpenVZ ported to ARM (Gumstix Overo). Parallels company is in top 10 Linux kernel contributors with their patches for Linux containers. Our contributions to the kernel at that time was PID, IPC, and network namespaces, with the last one being the biggest (mostly developed by xemul@ and den@).

2011

• Jul 15, 2011 - Pavel Emelyanov sent initial RFC and code (http://lwn.net/Articles/451916/). The idea of CRIU of course came up earlier when we figured we (or anyone else, for that matter) can't possibly merge in-kernel checkpoint/restore. Re-implementing it in userspace looked crazy for everyone including me, and Andrew Morton's and Linus Torvalds' initial

reaction was similar ("some crazy russians").

• Sep 23, 2011 - first commit to CRIU project

2012

• Jul 23, 2012 - first CRIU public release
• Oct, 2012 - vzctl for upstream Linux kernel is available

2013

• May, 2013 - announced OpenVZ maintenance partnership http://openvz.livejournal.com/44228.html

2014

• Nov, 2014 - Parallels announced merging OpenVZ and Parallels Cloud Server into single common open source codebase

2015

• Apr, 2015 - Parallels company opensources the most components of their own commercial product Virtuozzo (formely know Parallels Cloud Server and Parallels Server Bare Metal)
