If you are trying to get snmpd working on a VE (for whatever reason, note you should strongly consider if you can accomplish what you are trying to do on the host) you will need to do a couple things.

Do this if you are seeing an error like this one:

error scanning interface data (expected 10, got 0)

First you need to run net-snmp 5.4.1 or later and second you will need to start it with the following option:

<code>-I -ipAddressTable</code>

So

<code>/sbin/snmpd -I -ipAddressTable</code>

From what I understand they are in the process of patching things on net-snmp to work with openvz a little better, but because of the duplicate IPs on the VEs (127.0.0.1) things aren't exactly standard.

== Installation and upgrade ==

===== What hardware is supported by OpenVZ kernel? =====
:See [http://www.swsoft.com/en/products/virtuozzo/hcl/ Virtuozzo HCL].

===== Why there are different kernel flavours available and what do they mean? =====
:See [[Different kernel flavors (UP, SMP, ENTERPRISE, ENTNOSPLIT)]]

===== 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, think about, that there is no support for disk quota inside VEs.
