Daniel:
This discussion used to be on the libvirt list, but seems
more appropriate for the users list so I am replying here.
At some time in the past we did set the MAC address on the
host interface
too, but it caused networking problems in some configurations
I see. Thanks for the background info.
I guess you have Cacti configured to pull stats directly from the
TAP
devices on the host ?
I am using bridging, but you are correct. I installed snmpd and
have Cacti pulling stats from it.
Cacti has the ability to run scripts to pull
in statistics, so my recommendation would be to add a shell script which
calls the 'domifstat' command in virsh
virsh domifstat DOMNAME TAPDEVNAME
The Cacti server is running in a separate machine, not on the host.
I guess I will have to find something that makes the domifstat data
available via an snmp interface.
Do you know of such a tool?
Thanks,
Neil
