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#

  1. 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:

    options nvidia NVreg_EnableMSI=0

    If the file /etc/modprobe.d/nvidia.conf does not exist, create it.

  2. Install the NVIDIA vGPU Software graphics driver in the guest VM.
