Hi all,
VERY strange issue that I've come across and can't seem to get my head around this .. so far I've tried diagnosing this for nearly 12 hours straight without being able to get to the bottom of it.
I'm running ESXi 6.0u2 build 3620759 (free license), on a custom build Asus P9x79 PRO running an E5-2660 Xeon and 64gb of DDR3 RAM. The system has four cards in it: IBM/LSI M1015 passthrough to a FileServer VM, an ATI X1300 boot graphics card, 2x Intel PT1000 Dual NIC cards and an AMD HD6450 Graphics card for passthrough. I have a Windows 10 VM which has been configured to use the AMD HD6450 configured in passthrough both Audio and Video to use as a test bench for a new type of system that we're currently building but don't have the actual hardware with us .. so we're shortcutting to get the development of the software achieved.
The VM has the latest VMWare Tools installed (via the console) and runs absolutely perfectly ... except when you decide to either reboot or shutdown the VM, the actual ESX host becomes unresponsive. Stops responding to network traffic, ESXi thick and HTML consoles don't response (naturally) but there are absolutely no errors on the screen, like a PSOD. It still displays the normal yellow console which is also unresponsive, so a very hard lock.
I've looked through the knowledgebase and found KB1030265 which I've followed and now have disabled interrupt mapping but this hasn't made a slight bit of difference.
Can anybody point me in a direction to either get logs from this thing or any suggestions to try and debug this? Appreciate that it's a tough call, especially since the hardware not everybody will be running etc but any experiences that are similar and things I can change/tune would be appreciated.
I'm tempted to drop back to ESXi 5.5 and see if that exhibits the same problem, which would indicate hardware faults, but I would have thought loading up the VM with 1080p graphics/sound would have caused a bigger issue than shutting down the VM.
Thanks
Dean
