the guest vm’s ether driver is virtio_net , I test iperf3 between mac mini and the vm guest , from the host server ,I found the qemu process almost took 100% cpu . is it normal ?
thanks !
Need more details.
incus config showof vm- Guest OS
- Nic speed / iperf result
Think thats all.
guest os : vyos
iperf result , if two nodes on the same incus network , speed looks good ,can up to 5Gb . only 1 cpu for this vm . during the test ,I found thread cpu/kvm took much cpu .
incus config show vyos-01

I see this kind of issues only when using *BSD based distros, my 10G network doesn’t care else.
You could research hardware acceleration and if it is on.
incus is using qemu with kvm acceleration under the hood, same as others like Proxmox, oVirt and so on.
Else wait for answer from someone deeper into that.
Please also give the Nic Type and Speed.
