AW: debian 10, vm cant connect to the host bridge
someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work.
Here is my current host interface config:

Qdisc requeue should be void?
There is an design problem with the qdisc interface that causes qlen related bugs
in netem, tbf, and other qdisc''s that peek at the top of the queue. The problem is
that requeue needs to be called from the dequeue function but requeue can fail.
If requeue fails, then the calling qdisc can not properly handle the error. If it
returns NULL, then the parent...

More on qdiscs
I notice one other small problem with my modified version of SFQ.
The fact that packets can be dropped at dequeue time is incompatible
with the way HTB (and probably CBQ and others modeled on it) keep
statistics. When I fill a low rate queue causing packets to expire
and be dropped at dequeue I get interesting statistics like this:
This is my variant of SFQ

Setting a VM's vnetX qlen in the XML file
Hi all,
I have a two-node HA RHEL 6 setup hosting VMs. These use
static/standard bridges and all has worked wonderfully. Now though, I
need to adjust the qlen value of the vnetX devices for a given guest VM,
which I can do with:
ip link set dev vnet0 qlen 6000
The problem with this approach is two-fold though;
1. I need to determine which vnetX is connected to a VM.
2. If the VM live-migrates, the qlen of the vnetX on the new host needs
to be update...
