PfSense 2.3 on Hyper-V 2012 (R1) - only 3 network adapters are working
-
Hmmm… That isn't good. I'll have to test.
I have a Hyper-V install coming up that we were planning on using 5 vNICs for... A plan B would be to do the VLAN config in pfSense instead of at the NIC/vSwitch level, but I think it is cleaner to not do it like that...
-
Just FYI, I built a Gen 1 VM on Hyper-V 2016 TP5 with 5 NICs and all 5 NICs worked fine in pfSense.
I'll double check on Hyper-V 2012 R2 tomorrow….
-
Last update… I went back and made a 5 NIC pfSense VM in Hyper-V 2012 R2 (GEN1 VM) and all 5 NICs showed up just fine there too....
So I don't see an issue at this point.

You got pfsense 2.3 to work with 5 NICs on 2012r2?
Hmm. You just ran the regular installer without changing anything?
-
Yes. In fact I moved a production physical server with 6 nics to a HYPERV 2012 R2 gen 1 VM with 6 nics this afternoon via a clean install of 2.3 and then restoring backup and reassign the interfaces. Everything working perfectly.
I used the CD installer ISO, and took all defaults during the pfsense install.
I used regular nics (not legacy) in the vm, and they showed up as hn0-5 (6 nics), each nic set to a different vlan.

The FreeBSD patch linked above changes a wait from 500 (who knows the units?) to 5 * hz (5 seconds). I wonder if my physical host is just too slow to initialize everything in 500 and yours is not?
Can I ask what cpu you have in your host? Mine has an Opteron 4170 HE (getting a little long in the tooth…)
-
FWIW, i have the same problem with pfSense 2.3 and Window Server 2012, not R2.

Had exact same problem (only 3 NICs detected, error above for the 4th) on Windows Server 2012 Hyper-V. Upgraded my server to Windows Server 2012 R2 and the problem was resolved.

I doubt it is timing related. It works fine for me even doing hyperv nested in VMware Workstation on a dual-core i5 processor. That has to have more latency/timing issues than your opteron….
To answer the actual question, my hyperv hosts are E3-1240v3 processors.
In relation to the other post, I have never tried it on 2012 R1 - I upgraded all those years ago, so don't have any left.
-
I have the exact problem. Windows Server 2012 (not R2).
The fourth NIC does not appear on pfSense.
Does anyone know how to patch/fix the kernel as per DD post (https://lists.freebsd.org/pipermail/svn-src-stable-10/2016-March/008308.html ) ????
I cannot upgrade my server to R2, since I don´t have license -
I am wondering what is the value of kern.hz on the affected installations.
This patch (https://lists.freebsd.org/pipermail/svn-src-stable-10/2016-March/008308.html) deals with the problem by making the time dynamic depending on kern.hz value instead of the, believed, default 100 kern.hz for VMs.
-
did you tried the patch?
can you provide instructions do apply it?

Have the similar problem on 2012 R2 after installing 2.3.2.
It seems that problem with NIC drivers and not enough cpu performance.
I have gigabyte brix which through hyper-v VLAN runs pfsense.After updating to latest realtek drivers and adding 1 core to VM, problem disappeared.
Just now tried to remove 1 core and VM did not detect any hn0, hn1, hn2 at all.on 2.2.6 everything was ok even with 1 core and old realtec drivers.
-
It seems like patch1 for 2.3.2 solved the problem.
Right now pfsense successfully started with 1 core, all NICs were detected. -
I have tried upgrading to 2.3. And I find that PFSense will not detect all NICS. I have now tried upgrading to 2.4 with the same outcome. I have also tried applying the above patch to 2.4 via the System Patches Package that I installed. However, when I test the packages, it states there is no file to patch
I cut and pasted the code from https://lists.freebsd.org/pipermail/svn-src-stable-10/2016-March/008308.html
and created three patches based on the 3 sections of code.Can anyone please advise how to apply this patch to 2.3 and or 2.4.
e.g.
/usr/bin/patch –directory=/ -t -p1 -i /var/patches/59f7b6a679008.patch --check --forward --ignore-whitespace
Hmm... Looks like a unified diff to me...

RESOLVED*****
Upgraded MS-Server 2012 to MS-Server2012R2 and everything now works as expected.
I have attempted to update a few MS-Server2012 Hyper-V PFSense firewalls and all have failed.
I will now update all HOST OS to 2012 R2.
