Hello there,

I’m trying to install KVM onto a Drive AGX Xaier to run multiple guest OSes.

Installing qemu, libvirt and all the other required packages via apt works fine. Performing several checks like the ones below indicate that hardware virtualization is not available which is needed for KVM:

$ egrep -c '(vmx|svm)' /proc/cpuinfo
0

$ sudo kvm-ok
INFO: /dev/kvm does not exist
HINT:   sudo modprobe kvm
modprobe: FATAL: Module msr not found in directory /lib/modules/4.14.102-rt53-tegra

I believe, however, that hardware virtualization is available on the AGX (please correct me if I’m wrong). Therefore my question is how to enable hardware virtualization on the Drive AGX?

Thanks for your help!

Dear @t.mueller,
Please see Where can I find the Virtualization Programming Guide?

Hi, @t.mueller

As some developer site pages, e.g. NVIDIA DRIVE SDK | NVIDIA Developer, and the topic @SivaRamaKrishnaNV pointed out mention, NVIDIA Hypervisor is part of the software stack of DRIVE OS. Thanks.

Hello,

Thanks for your answers. As mentioned in the post referred by @SivaRamaKrishnaNV, the Virtualization Programming Guide is not available through the Developer program. We already had a call with our Nvidia representative, saying that it is only available through the partners program.

Sine I cannot use the Nvidia Hypervisor without documentation, I’m trying KVM.

Got it. But DRIVE OS supports only our hypervisor.
