Re: [vfio-users] Nvidia glitches on Windows 10 guest



I forgot to explain something which is maybe important for my issue.

I have this problem ONLY when i use both NVIDIA cards. My 960 card is for Linux and the 970 for Win10 Guest.
If i use only the 970 for the Guest and the IGP Intel for the Host (and disable the 960), i can allocate without problem more than 4GB RAM to the Guest.

I did a bootable memtest and i have not errors with my RAM ...
I install actually Win7 to see if this issue appears with it too.

Would you be able to run a Bootable memtest just to make sure you dort have faulty ram?

Test if i allocate 4GB to the VM.

AnonHugePages:         0 kB
HugePages_Total:    2050
HugePages_Free:     2050
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:       2048 kB

- VM launched :
AnonHugePages:     10240 kB
HugePages_Total:    2050
HugePages_Free:        2
HugePages_Rsvd:        0

To enable the Hugepages and to allocate 4096, i only follow the Debian Wiki like i said. And concerning the VM, i only add in the .xml :
"<memoryBacking>
         <hugepages/>
</memoryBacking>"

And when the VM is running does  HugePages_Free in /proc/meminfo decrease from HugePages_Total?
