ATTO ExpressSAS H680 – PCI Passthrough

Sorry for resurrecting an old thread, but I just tried this on my system as well, and it too, also, did not work.

This is what's in my /etc/default/grub:

Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt net.ifnames=0"

I also checked to make sure that it is in its own IOMMU group, which it is;

Code:
IOMMU Group 26:
    0a:00.0 Serial Attached SCSI controller [0107]: ATTO Technology, Inc. ExpressSAS 6Gb/s SAS/SATA HBA [117c:0042]

VM crashes the entire host when I attempt to start said VM.

That's a bit of a bummer.

Figured that I'd share my experiences with the ATTO ExpressSAS H680 here as well.

Thanks.
