Hyper-V Host Crashing

[minooch 1]

Hi,

 

My server is crashing consistently when playing some TV series (been running strong for many MANY months prior) - Current Emby version is 3.0.5945.0

 

I'm running a Windows 2012 R2 server, the only service installed is Hyper-V.

 

One of the VMs is running another 2012 R2 with loads of storage & it runs Emby

 

Another VM is pfSense (dedicated nics)

 

Within about 60-120 seconds of streaming a few shows (over the net), the Hyper-V host BSODs. The host reports error 20001 hypervisor_error (can't find anything solid about it)

 

The Emby server reports nothing, no logs at all

 

pfSense sometimes creates a vague report with no indicated of anything.

 

I'm at a total loss, the server isn't having any other issues at all

 

Has anyone experienced this, or have any ideas?

 

Cheers

BUMP

 

I though maybe it was the Windows VM that was making it crash, so I made a new CentOS VM. It crashed too although only the VM not the host.

 

here is a screen shot of the crashed VM

Any thoughts? Anyone?

I have no issues running in hyper-v on Windows Server 2012 R2 as host....  but in my case, my VM is running Windows 7.

Hi,

 

I have Windows 10 running on a server with the Hyper-V role, with XPEnology running as a VM which runs Emby as a package.

 

I've had months of stability then for whatever reason I would start to see the server crashing at around the same time each day - for days on end.

 

I believe it was down to an external USB drive that I had shared via the Windows 10 and/or contention on the OS drive. I've since removed the USB external drive and also removed some of the disk load on the OS drive. No crashes at all for a month now!

 

When it did crash I would just see the BSOD, with no real info.

 

Also, might be just a coincidence but I also have a pfSense instance as well as a number of other VMs on the same box.

Have you installed any updates new drivers recently? A new driver such as a NIC driver or motherboard driver may be causing it. Can you isolate the issue to certain file types? Is the Emby server transcoding and putting the CPU under a unusual large load?

 

I found this TechNet post, https://social.technet.microsoft.com/Forums/windowsserver/en-US/9ef4d685-8618-43b2-9455-5463a1e04555/stop-error-0x00020001?forum=winserverhyperv

 

Might require a BIOS update if it's just failing under the load. The Stop 20001 message is unfortunately a generic stop error.

 

Also found this, https://support.microsoft.com/en-us/kb/2550569 but not sure if it really applies to your situation.

 

I've been running Hyper-V for years but I use Stand Alone so it's essentially server core and only has Hyper-V Services running. I run everything in VM's. Including a dedicated Emby VM which itself is 2012 R2.

 

Microsoft in it's every widening attempt to make things more difficult, moved the download page for Hyper-V Stand-Alone. It says "evaluate"  but it's unlimited and free if your interested.

I think I found the problem. I removed a PCI-E USB 3 card. No crashes since... I'll keep testing & update again later

well done!
