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:
4560 Jan 22 17:43:33 ubuntu-24 ovs-vsctl: ovs|00001|vsctl|INFO|Called as ovs-vsctl

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"

This doesn't look right, because you have no QoS defined here ...

But libvirt is still trying to set some. Are you sure you're pasting the
correct XML? Also, your kernel is probably lacking some of the required
features, like u32.

Dear Michal:
I'm sorry. The pasting XML I described earlier is wrong, and the real thing is:
<interface type='bridge'>
<mac address='52:54:00:0a:2b:2a'/>
<source bridge='lcs_br_1'/>
<virtualport type='openvswitch'/>
<bandwidth>
<inbound average='0' peak='0'/>
<outbound average='0' peak='0'/>
</bandwidth>
<model type='virtio'/>
</interface>
I'm really sorry. I forgot I had QoS defined on the virtual machine.
And this problem doesn't happen every time. I encountered this problem when I used the
same XML to create about 100 virtual machines on a hypervisor.

It doesn't make much sense to set these to zero. The domain will not be
able to receive/send any packets through the interface. Also, this must
be some older libvirt because when I try the latest git HEAD it doesn't
even accept zero values there.
<model type='virtio'/>

This suggests it is a kernel problem.
