Red Hat Enterprise Linux and CentOS 6 VMs hang during driver installation

Description

During installation of the NVIDIA vGPU software graphics driver in a Red Hat Enterprise Linux or CentOS 6 guest VM, a kernel panic occurs, and the VM hangs and cannot be rebooted. This issue is observed on older Linux kernels when the NVIDIA device is using message-signaled interrupts (MSIs).

Version

This issue affects the following guest OS releases:

Red Hat Enterprise Linux 6.6 and later compatible 6.x versions
CentOS 6.6 and later compatible 6.x versions

Workaround

Disable MSI in the guest VM to fall back to INTx interrupts by adding the following line to the file /etc/modprobe.d/nvidia.conf:
Copy

Copied!
```
            
            options nvidia NVreg_EnableMSI=0
        
```
If the file /etc/modprobe.d/nvidia.conf does not exist, create it.
Install the NVIDIA vGPU Software graphics driver in the guest VM.
