<hr />
<div>== General ==<br />
===== What is a Virtual Environment (Virtual Private Server, VPS, VE)? =====<br />
:See [[VE]]<br />
<br />
===== Who needs OpenVZ? How it can be used? =====<br />
:See [[Use cases]]<br />
<br />
===== How is OpenVZ different from other technologies? =====<br />
:See [[Introduction to virtualization]]<br />
<br />
===== How is OpenVZ updated and why it is secure? =====<br />
:See [[Security]]<br />
<br />
===== I want to show my appreciation to OpenVZ and put some logo to my site. Where to get it? =====<br />
:See [[Artwork]]<br />
<br />
== Installation and upgrade ==<br />
<br />
===== What hardware is supported by OpenVZ kernel? =====<br />
:See [http://www.swsoft.com/en/products/virtuozzo/hcl/ Virtuozzo HCL].<br />
<br />
===== Why there are different kernel flavours available and what do they mean? =====<br />
:See [[Different kernel flavors (UP, SMP, ENTERPRISE, ENTNOSPLIT)]]<br />
<br />
===== How do I rebuild the kernel? =====<br />
:See [[Kernel build]]<br />
<br />
===== What does 021stab018 in OpenVZ kernel version mean? =====<br />
:See [[Kernel versioning]]<br />
<br />
===== How can I check package signatures? =====<br />
:See [[Package signatures]]<br />
<br />
===== Is it possible to run x86 VPS on a x86_64 arch? =====<br />
: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.<br />
<br />
===== What filesystems should I choose for saving my VEs? =====<br />
The safest choice is ext2/3 to save your VEs. Remember that ReiserFS is less stable than ext2/3.<br />
If you choose to use XFS, there will be no support for disk quota inside VEs.<br />
<br />
== Networking ==<br />
<br />
===== How do I set up VPN for a VE? =====<br />
:See [[VPN via the TUN/TAP device]]<br />
<br />
===== What is veth and how do I use it? =====<br />
:See [[Virtual Ethernet device]]<br />
<br />
===== Why doesn't net-snmpd work on my VEs =====<br />
:See [[SNMPD on VEs]]<br />
<br />
== User Beancounters ==<br />
<br />
===== What are those User Beancounters? =====<br />
See [[UBC]].<br />
<br />
===== What units are UBC parameters measured in? =====<br />
See [[UBC parameter units]]<br />
<br />
===== How do I set up a VE which is able to get X Mb of RAM? =====<br />
See [[Setting UBC parameters]].<br />
<br />
===== I can not start a program in VE: it reports out of memory. What do I do? =====<br />
See [[Resource_shortage]].<br />
<br />
===== How can I reset <code>failcnt</code> in <code>/proc/user_beancounters</code>? =====<br />
See [[UBC failcnt reset]].<br />
<br />
== Troubleshooting ==<br />
===== My kernel crashed. What should I do? =====<br />
:See [[When you have an oops]]<br />
<br />
===== I see a lot of processes in D state. What does that mean? =====<br />
:See [[Processes in D state]]</div>Mfedyk
