You don't have a Broadcom NIC, by chance?

All Intel.

I really think it's related to the Hyper-V Nic Driver & Linux. Make sure the Hyper-V host has all windows updates installed. You could also Disable VMQ and Disable Large Send Offload Version 2

I moved to a different host last night. I disabled VMQ, not Large Send Offload though, I will look into that.

So no issues hitting the local firewall. Now the other wise of the WAN but still "local"?

This is the WAN access IP address.

PBX

Desktop

Tested that ping and did not see any errors.

[scottalanmiller]

Yup, testing from here and not seeing packet loss. Looks good at the WAN side, as far as the pure WAN link.

I've tested it from my house as well and it works fine. So that tells me it is something internal.

Have people had issues running a PBX on Hyper-V? I've heard about the linux driver issues that 2008 had, but I was fairly certain that those had been resolved.

I run PBX in a Flash and Free PBX on Hyper-V no issues.

I have ran Elastix 2.4 as a demo on Hyper-V.

Are you running it as a Generation 1 or Generation 2 VM?

Generation 1

More ping data all started at about the same time for about the same length.

VM Host 1 - Windows and Linux Server
Windows Server

Linux Server

VM Host 2 - PBX
PBX

That really makes it seem like a driver or similar issue. Very weird.

[coliver]

I'm really concerned as to why it would pop up 5 months after the original deployment. Even if it were a driver issue. Could a Linux update have caused this?

[scottalanmiller]

A Linux update could have, of course. But were both of these systems patches recently? It is far more likely to be a HyperV issue. But either is certainly possible.

No, neither were updated prior to last Friday.

[scottalanmiller]

Seems pretty unlikely to be Linux then if multiple, non-patched systems were impacted.

[coliver]

From the Meraki GUI I can do a similar ping test. It shows no loss of packets and a 1-4ms response time. To the 204 IP address.

[scottalanmiller]

What Linux is the "other" one?

CentOS 6.6 final. FreePBX runs on CentOS 6.5 final.

This is one running OpenSuse

Does a Windows VM on the hyper-V server have the same issue?
Also what about a UEFI linux running in a Generation 2 Hyper-V VM?
