I would like to get some ideas and opinions on matter of libvirt netfilter application in KVM environment. I am looking for some easy way to control it with an API and possible experience with that and its performance in real life application.
Hello,
on a PC with Debian 8 I try to use a Bash script with Netfilter rules so that only traffic goes in and out that is wanted. For that I set all 3 default policies to "drop". The machine uses DHCP to get its IP, gateway and DNS. And I never checked so I was quite surprised that my... (1 Reply)

LIBVIRTMIB_SUBAGENT(1) Virtualization Support LIBVIRTMIB_SUBAGENT(1)NAME
libvirtMib_subagent - SNMP subagent for libvirt
SYNOPSIS
libvirtMib_subagent [OPTIONS] [LISTENING ADDRESSES]
DESCRIPTION
The libvirtMib_subagent provides SNMP functionality for libvirt. Therefore it is now possible to gather and set domain status over SNMP
from one place. This allows to create views of entire platforms end to end.
It communicates with SNMP agent over AgentX protocol (RFC 2741) and extends agent's set of infomation provided. Therefore, we need a
running SNMP agent. This behaviour can be avoided using -M option.
The libvirtMib_subagent understands these OPTIONS:
-f Don't fork. Run in foreground.
-D[token[,...]]
Turn on debugging output for the given TOKEN(s). Without any tokens specified, it defaults to printing all the tokens (which is
equivalent to the keyword '"ALL"'). You might want to try ALL for extremely verbose output. Note: You can't put a space between the
-D and the tokens.
-H Display a list of configuration file directives understood by the agent and then exit.
-M Run as a normal SNMP Agent instead of an AgentX sub-agent.
-xADDRESS
Connect to master agent at ADDRESS (default "/var/agentx/master"). The address can either be a Unix domain socket path, or the address
of a network interface. The format is the same as the format of listening addresses described below.
-L Do not open a log file; print all messages to stderr.
The last optional LISTENING ADDRESSES specify on which addresses should subagent running in normal SNMP Agent mode listen for incoming
requests. See snmpd for further information.
