[ovs-discuss] Continuous messages: engaging governor with XX kB hash table

[Carlos Velasco]

Hello,

I have created a simple bridge with 2 VMs ports and 1 ethernet physical port.

# ovs-vsctl show
40e43335-0f9e-49b3-9c25-2dcadebac952
    Bridge "br0"
        Port "eth0"
            Interface "eth0"
        Port kvmone
            Interface kvmone
        Port kvmtwo
            Interface kvmtwo
        Port "br0"
            Interface "br0"
                type: internal

When there is a lot of traffic (by ex. torrent) from a VM, I get a lot of these entries in the message log:

...

Is this normal?
