Hello,
I want to report to you a really big bug.
vfio passthrough dont works with Sata controler (an AsMedia 1061) ! When i
try to use vfio with this controler it work only once.
When i use vfio for VGA i can reboot (or shutdown and start again) my VM
with out problem, but for any other PCI card the VM refuse to reboot.
In dmesg i have this error :
[ 404.206866] dmar: DRHD: handling fault status reg 2
[ 404.206870] dmar: DMAR:[DMA Write] Request device [07:00.0] fault addr
