Hello:
I have a host running two KVM guests. The guests use br0 and each has a static IP address.
I am trying to figure out if there is a way to use snmpd on the host to measure the traffic usage of the guests. I do not want to require anything running on the guests since I do not control them.
Looking at netstat -in on the host, I see this info:
Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg br0 1500 0 237609 0 0 0 13615 0 0 0 BMRU eth0 1500 0 967594 0 0 0 354576 0 0 0 BMRU lo 16436 0 63 0 0 0 63 0 0 0 LRU virbr0 1500 0 0 0 0 0 32 0 0 0 BMRU vnet0 1500 0 29802 0 0 0 306940 0 0 0 BMRU vnet1 1500 0 311556 0 0 0 789331 0 0 0 BMRU
Looking at the firewall logs for packets that hit the firewall, I see that vnet1 is connected to guestA and vnet0 is connected to guestB.
Is there a better way to determine which vnet is connected to which guest?
Also, does the mapping change when I stop and start guests or reboot the host?
Thanks, Neil
