You have options of having support from Parallels, free support on mailing lists and forum, or switching to Parallels Cloud Server which is much more than just a commercial version of OpenVZ.
Parallels is now offering an OpenVZ Maintenance Partnership program. The program provides bug resolution support and feature development to the OpenVZ community. The OpenVZ Maintenance Partnership has a small annual fee and provides two benefits to partnership members.
- Partnership members will receive a support ID that will allow them to submit up to10 high priority bugs per year. These bugs will be placed at the highest priority level in the development stack.
- Partnership members will also be able to submit a feature request(s) which will be reviewed by the Parallels engineering team. They will work with you to clarify the requirements and implementation options and provide an implementation estimate and a schedule.
 Free support
You can get support through the mailing list, Bugzilla and Support forum. Both developers and members of OpenVZ community can answer your questions there, although there is no guarantee of any kind. Be sure to browse/search this wiki, make a search within the mailing list archives and forums before asking your question.
