Here we list major project milestones.

1999

  • 1999, Nov: Alexander Tormasov visited Singapore and propose to Sergey Beloussov new direction - container virtualization and formulate three main components: containers as a set of processes with namespace isolation, file system to share code/ram and isolation in resources.

  • 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

  • Feb, 2000: we are open office at MIPT and start working on first mockup version of Virtuozzo.
  • Jul 2000 (may be other time): connect two computers to Internet, one with vz 0.1, 5k VE during summer.
  • Nov, 2000: Limited public beta testing (providing free VEs to people to run their stuff).

2001

  • end of 2001 - beginning of 2002: start working on VZWin

2002

  • Jan, 2002: SWsoft (now known as Odin) initially released a product for Linux named Virtuozzo[1]

2004

  • Dec, 2004: Initial release of Virtuozzo for Windows [2]

2005

  • 2005: SWsoft created the OpenVZ Project to release the core of Virtuozzo under GNU GPL.
  • ~2005: SWsoft buy software development company with FreeBSD similar staff, do develop it and later drop (small number of clients).

2006

  • 4 Aug, 2006: OpenVZ is available in Debian Linux [3]
  • 16 Aug, 2006: OpenVZ rebased to RHEL 4 kernel [4]
  • Oct, 2006: OpenVZ ported to SPARC[5] and PPC[6]
  • Nov, 2006: OpenVZ adds live migration capability [7]

2007

  • 13 Mar, 2007: Port to RHEL5 kernel [8]

2008

  • 17 Apr, 2008: Rebase to kernel 2.6.25[9]
  • Oct, 2008: Port to ARM [10]. 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.

2011

  • Jul 15, 2011: Pavel Emelyanov sent initial RFC and code[11]. 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: Cyrill Gorcunov made [12] first commit to CRIU project

2012

2013

  • May, 2013: OpenVZ maintenance partnership [14]

2014

  • Nov, 2014: Parallels announced merging OpenVZ and Parallels Cloud Server into single common open source codebase[15]

2015

Surprise! Stay tuned.
