PfSense virtio networking under KVM

homa

The download link isn't available any more.

can anybody upload the driver.

thanks

Same here.

I will love to get a hand on these drivers.

rapidshare isn't serious man!

I guess you can use the other six services to download.

Apparently this mod breaks traffic shaper, the interfaces are not available under traffic shaper. I wonder if there is an easy way to fix it…

Try adding it to the list at line 3520 of /etc/inc/interfaces.inc

It may not really be altq capable, but you can try.

Will the virtio driver be included in the final release of PfSense 2.0?

It's mentioned in this thread that it's included since 2.0 but I won't get it working only by installing it manually.

"We have added this driver to 2.0. Please test a new snapshot and it should be present sometime tomorrow."

Hello,

i would bump this topic and ask, are there now virtio drivers in the latest pfSense 2.0 RCx?

@jimp

can you please make a statement and tell us if in the final pfsense 2.0 will be virtio drivers for kvm?

Thanx for answer.

after a view tests, i can say that the actual virtio driver didn´t work correkt. More than 3 network interfaces didn´t work correct (routing)

catfish

thanks for that information. did you also test the virtio disk driver?

valshare

hi,

no i didn´t test die virtio disc driver because of the trouble with the virtio net drivers. I think its better to wait for the offical, when there ever will be released.

I have tested successfull the network e1000 and iscsi disc drivers with pfsense.

paolo_denti

any news about that ?
are the virtio drivers included in the 2.0 final release ?

Hello!
Running pfSense-2.0-RELEASE-i386
Same problem here :)
On E1000 with KVM I'm getting 250-300Mbit/s
This isn't enough for internal routing (for example when using pfSense to route traffic between 192.168.x.x and 10.x.x.x).
I'm just curious about that.

Okay. Some tests.
Q1: why I have to exit shell and go into shell again (press 8…) to see new command (iperf) available after adding in packages?
Q2: reaching about 240-250Mbit/s DebianVM+virtio-net -> pfSenseVM+e1000 and pfSenseVM+e1000 -> DebianVM+virtio-net
Q3: there is no problem to reach about 900Mbit/s from DebianVM+virtio-net to the client.
Q4: timeouts on IDE drive attached in pfSenseVM. No such thing when using virtio-storage in DebianVM.
Both VM placed on the same storage - software mdadm RAID1 with 2 drives.

maybe this could help:

valshare

@TooMeek, thanx for the tests. Do you have testet the drivers that WetWilly has postet?

Regards, Valle

I tried the drivers that WetWilly has posted, but I can't see any virtio network interface in pfSense.
How can I catch the log of loading /boo/loader.conf?

WetWilly

well, the driver I posted is for freebsd 8.2 and 9.0

If I'm not mistaken pfSense 2. is based upon 8.1, so the driver most likely need (alot) tweaking.

Is inclusion of virtio drivers in pfSense planned in the near future?

I need a permanent virtual router solution to do inter vnet routing on KVM host using no NAT, firewall rules as needed, and OpenOSPFd (to distribute vnets to main hardware firewall/router dynamically) and first installed pfSense (2.0.1). It was functionally up to the task of course, but as it lacks virtio (and possible other KVM related optimizations) the performance was horrendous.

I gave it 1 CPU-core (Xeon E3 1220 3.1GHz) and 512MB RAM but it actually idled at around 50-60% CPU usage on the KVM host even though the actual usage in pfSense VM was about 100% idle under a couple of hundred connections and maybe around 1-20mbit/s traffic. This indicates a massive performance hit in the emulated VM-interface alone.
Testing routing performance with iperf I couldn't get more than about 450mbit/s and then the CPU was completely maxed out making the web interface unusable during the test.

Because of this I instead installed Debian Wheezy, activated forwarding and installed quagga for OSPF using virtio both for disk and network interfaces and this machine idles at 0-0.1% CPU usage on KVM host and during iperf tests the routing performance was a full 944mbit/s, which is as good as it possibly can get without jumbo frames etc, using only 13-16% CPU power on the KVM host which is very good.

Internal guest to guest performance using virtio and Debian guests was 19.5 gbit/s with iperf, so the performance is potentially extremely good. I don't know if FreeBSD can reach those speeds on a KVM host at all, but pfSense should at least be able to idle at around 0% host CPU usage and do plain routing at gigabit speeds without any problems to be an alternative for VM appliances in KVM based hypervisors.

As I have networked power monitoring on the power receptacles I could actually see the power usage decrease by several watts by replacing the pfSense VM with Debian because of the high idle CPU usage.
