General
What is a Virtual Environment (Virtual Private Server, VPS, VE)?
- See VE
Who needs OpenVZ? How it can be used?
- See Use cases
How is OpenVZ different from other technologies?
How is OpenVZ updated and why it is secure?
- See Security
I want to show my appreciation to OpenVZ and put some logo to my site. Where to get it?
- See Artwork
Installation and upgrade
What hardware is supported by OpenVZ kernel?
- See Virtuozzo HCL.
Why there are different kernel flavours available and what do they mean?
How do I rebuild the kernel?
- See Kernel build
What does 021stab018 in OpenVZ kernel version mean?
How can I check package signatures?
Is it possible to run x86 VPS on a x86_64 arch?
- Sure :) We actually did some work on that to enable migration of x86 VE from x86 to x86_64 and back, and to enable using 32-bit iptables in 32bit VE on an x86_64 system.
What filesystems should I choose for saving my VEs?
The safest choice is ext2/3 to save your VEs. Remember that ReiserFS is less stable than ext2/3. If you choose to use XFS, there will be no support for disk quota inside VEs.
Networking
How do I set up VPN for a VE?
What is veth and how do I use it?
Why doesn't net-snmpd work on my VEs
- See SNMPD on VEs
User Beancounters
What are those User Beancounters?
See UBC.
What units are UBC parameters measured in?
How do I set up a VE which is able to get X Mb of RAM?
I can not start a program in VE: it reports out of memory. What do I do?
See Resource_shortage.
How can I reset failcnt in /proc/user_beancounters?
See UBC failcnt reset.
