proxmox ovs and monitor traffic vm

[RFS77]

hi Gooday to every one


I'm new in proxmox and get confusion ,im just install proxmox 3.2 ver and create a ovs bridge as below


root@PR01:~# ovs-vsctl list-br
vmbr0
=================================================
Also create a vport1 and vport2 for each vm


But when im create a vm ,can't find the option select vport1 and 2 , just need to confirm ,
is promox support OSV work as virtual-BOX ?
If not , how can im create a port to separate each vm and create cacti to monitor each vm traffic.




root@PR01:~# ovs-vsctl show
79b13623-b540-4dad-ad35-80ec0212065c
Bridge "vmbr0"

Interface "vmbr0"
type: internal
Port "eth0"
Interface "eth0"
Port "vport1"
Interface "vport1"
Port "vport2"
Interface "vport2"
ovs_version: "2.3.0"


any one can confirm , thanks

Internal ports are not necessary in your case (you need them only in case of splitting VLANs and other special purposes).

Connect you virtual NICs in the VMs directly to your bridge:

Use Machine´s configuration, "Hardware" Tab and assign the bridge (vmbr0 in your case) to the Network Device. You can connect as many NICs as you like from any virtual machine to the same bridge.

Kind regards

Better than theory: Post both

ifconfig -a
ovs-vsctl show

when VMs are running and I´ll explain.

thanks . im run below cmd and can see below

root@PR01:~# ovs-vsctl del-port vmbr0 vport1
root@PR01:~# ovs-vsctl show
79b13623-b540-4dad-ad35-80ec0212065c
Bridge "vmbr0"
Port "vmbr0"

Interface "eth0"
Port "tap100i0"
tag: 1
Interface "tap100i0"
Port "tap101i0"
Interface "tap101i0"
ovs_version: "2.3.0"

and ifconfig -a // show below

tap100i0 =vms1
tap101i0 =vms2 correct ? so every vm create ,will also create a tap00xx intefaces

then i need to get the mrtg snmp to get the data ,so im need to install a cacti server up fist.........

Exactly! Monitor these interfaces and that´s it!
