Good evening to everyone,
this is my first time that i write here in community forum, sorry to everyone for my bad English I'm come from Italy.
I have a problem with ESXi 5.5 last update with vCenter, the host is a Dell C1100 with 36GB DDr3, two xeon L5520 with an ati Radeon 6450 in the PCI express slot.
All components are working, BIOS version is 1.84 I have set all the settings on the BiOS for PCI passthrough and Nested Virtualization.
I Have created a Virtual Machine with 8 GB vRAM and 8 vCPU and the OS is Windows Server 2012 R2, network card is the VMXNET3 and no problems with networking.
Now the problem.
Before the hyper v role installation, I have set the PCI passthrough to the virtual machine and the systems detect correctly the card and no problems with driver installation.
But when I try to install hyper v role (installations gone fine but the problem appears after reboot), the ESXi system crash with a PSOD. I have a picture of the screen, i have attach it here with the post.
I tried to deactivate the PCI passthrough on the VM and it boot correctly without create any PSOD, hyper v working without problems, I can create nested virtual machine x64 too.
So if I try to activate the PCI passthrough of the Ati 6450 on the hyper v virtual machine the system crash.
All the operations are made with vSphere Web Client.
Thank you very much to everyone.
