Since this problem is still present in this latest series I will do another try to see if anyone has the same problem.

Doing a ps aux on my host-machine I get high cpu-usage, the host machine is running Ubuntu 16.04 with a 4.6.2 kernel.

libvirt+  3481  9.1  8.6 2207876 1417684 ?     SLl  jun14 259:22 qemu-system-x86_64 -enable-kvm -name fw -S -machine pc-i440fx-2.5,accel=kvm,usb=off -cpu host -m 1024 -realtime mlock=off -smp 2,sockets=2,cores=1,threads=1

While on the opnsense machine is almost always idle around 0-2% cpu running the latest development build, OPNsense 16.7.b_394-amd64.

Load average   0.16, 0.15, 0.15

Im using pci-passthrough, so no virtual devices for network.

Is anyone else using KVM? Anyone else see this problem?

Hi.

I run OPNSense 15.7 in a virtual machine (qemu/kvm) on an Ubuntu 15.4 installation.

CPU usage in OPSense is around 3%, but the virtual machine uses about 20-30% CPU.

I do not use virtio-network but rather PCI-passthrough on Intelbased HP NICs.

Anyone else seen this behavior?
