I've searched a lot to resolve the following issue, but nothing helped me.

My problem is, that starting up a first-gen vm locks up the whole host. Only a hard reset helps. Second-gen vm starts and runs perfectly. The freezes happened on 3 different vms. FreeBSD, Ubuntu, Windows Server 2008R2, while Windows 8.1 on second gen config works perfectly. Im using this pc mainly as a workstation. No eventlog errors nor dumps are generated.

My system:

  • Windows Server 2012R2
  • FX-8350, non OC
  • ASRock 870 Extreme R2 (Crappy board imho)
  • 32GB DDR3 1866@1600 (My motherboard, against the "support" for 1866ram won't work with full speed)
  • 120GB SSD
  • 4.5TB Storage space device

I dont think that its due to my system, because vmware workstation was running without problems.

Did I forget to configure something? Any help is appreciated.

P.S: Even deactivating C1E, C6, C&Q didnt work.

P.P.S: With no virtual network adapter set, the system still locks up. Creating a first gen vm without any hdds and network and launching works. Attaching a boot dvd causes the host to freeze.

The host freezes as the gen1 vm begins to boot, doesn't matter if from dvd or hdd

  • What is a "first-gen" VM, exactly? – joeqwerty Oct 6 '13 at 14:24

    Hyper-v in Windows server 2012r2 has a new feature, called second-generation vm. The first-gen vm has the same featureset as the versions before – user192856 Oct 6 '13 at 14:27
  • Try running sfc /scannow against the host... sounds a bit like a corrupted installation. – Chris S Oct 6 '13 at 14:33
  • @ChrisS: The system scan did't find any integrity violations. Also, yesterday, as this problem occured the first time, I had to reinstall the os. I forgot to turn off autobooting the vm, so the host got unusable. – user192856 Oct 6 '13 at 14:45

    I don't think I would run anything like this on a "Crappy board imho". – Michael Hampton Oct 6 '13 at 17:26

Got it... The reason was the mainboard. It doesnt suprise me anymore that professional software has certified hardware to run on. I was the victim of "it shall run everywhere syndrome".

Bought a high-end ASUS board, now everything works like a charm.
