Ubuntu VM - continuously port is entering blocking state

[jrp]

Network performance on the VM is very poor and I think it's because of:

Code:

Feb  3 13:02:17 truenas kernel: br0: port 3(vnet6) entered blocking state
Feb  3 13:02:17 truenas kernel: br0: port 3(vnet6) entered listening state
Feb  3 13:02:17 truenas kernel: audit: type=1400 audit(1675450937.680:60): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="libvirt-4552435a-95f8-4e6e-960d-39b09f024244" pid=2107187 comm="apparmor_parser"
Feb  3 13:02:23 truenas kernel: kvm [2107190]: vcpu0, guest rIP: 0xffffffffb6895f14 disabled perfctr wrmsr: 0xc2 data 0xffff
Feb  3 13:02:32 truenas kernel: br0: port 3(vnet6) entered learning state
Feb  3 13:02:47 truenas kernel: br0: port 3(vnet6) entered forwarding state

I have seen blocking posts with respect to Kubernetes but I am not using but a native VM install

Any guidance to resolve?

I have the same issue. I am an truenas scale 22.12.1 and have a also a bridge interface for a ubuntu vm.
In the ubuntu vm i als have the issue that the network speed is very slow. or sporadic slow.
iperf3 between truenas and vm is around 30Gbit/s with virtio driver and when I do a speedtest in the vm I get onle 20-50 mbit down and > 100 mbit up. The wierd thing is sometime it works and I get the full bandwith, the same as in truenas about >500mbit up and down. It seems like a power saving issue. I also tried to disable hardware offloading in truenas but it does not help.
Has anyone an idea what problem this could be or what things i can try to find it out?
