RE: Wish help and concern about Intel IGD iommu passthrough for our IDV product plan！

[Zhao, Yan Y]

Can you confirm that host os is in text mode (init 3) and no running processes like Xorg in host?
Otherwise, guest gpu would hang.

Hi, We are cloud desktop product and solution vendor in China.
Intel IGD iommu passthrough is core tech point in our idv plan.

I have test IGD passthrough on Ubuntu 18.04/CentOS 7/Fedora 25，and with graphic hardware：
00:02.0 VGA compatible controller: Intel Corporation Iris Graphics 540 (rev 0a)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
...
Sometimes ok and sometime not.
I have asked and discussed in vfio and intel gvt mail lists.
We wish more help from intel engineers, thank for your concern!

Best Regards,
Acewind
