Hi all,
When I created a virtual machine using virDomainCreateXML, with virtualport
type was openvswitch, and virtual machine creation failed. The error message is:
internal error: Child process (/sbin/tc filter add dev vnet110 parent ffff:
protocol all u32 match u32 0 0 police rate 0kbps burst 0kb mtu 64kb drop flowid
:1) unexpected exit status 2: RTNETLINK answers: Invalid argument
The Domain XML file the <interface> section like this:
<interface type='bridge'><mac address='52:54:00:71:b1:b6'/><source
bridge='ovsbr'/><virtualport type='openvswitch'/><address type='pci'
domain='0x0000' bus='0x00' slot='0x03' function='0x0'/></interface>
I looked at the system log and it looked like an ovs port problem:

However, when I use "tc" to manage "vnet*" of an existing virtual machine, it
still returns the same error.

We have an error talking to the kernel
Is there any reason for this problem? Thank you very much.
Below some information about my machine:
libvirt version: 3.4.0
ovs_version: "2.8.90"
