[RESOLVED] PCI Passthrough in KVM

[simon_lefisch]

Maybe someone else can answer this....can I install qemu-kvm-ev over my existing qemu-kvm installation and not have to reinstall my VMs or would I have to remove the qemu-kvm package first, install qemu-kvm-ev and redo my VMs? I assume I can just install over the existing qemu-kvm, but any existing VMs would not be able to take advantage of OVMF/Q35. Just want to confirm before I take the plunge.

Ok I was able to figure out what my issue was....

everything was enabled correctly in BIOS. I reconfigured grub according to @jlehtone, however my mistake was that I reconfigured grub for BIOS and not UEFI (which is what my system runs). Once I reconfigured for UEFI, I was able to pass the SATA PCI card Bus to my FreeNAS VM and the 2 HDDs I had attached to the cad now show up.

@TrevorH and @jlehtone, thank you so much for your help. Marking as resolved.

This is part of my /boot/grub2/grub.cfg file

There should be no /boot/grub2/grub.cfg in UEFI system.
I did assume that you have legacy BIOS install, because you wrote what you wrote.

(Almost did ask why have BIOS install. Didn't.)

That path does exist in /boot but like I said, I ran the grub2-mkconfig for /boot/grub2/grub.cfg rather than /boot/efi/EFI/centos/grub.cfg. Forgot that it matters whether you're running legacy or UEFI. Regardless, many thanks for your help....really stoked I was able to get this going here
