Hi Guillaume,

I just tried updating again to latest build (0.1.113), but this time I am
using the WIndows 8.1 driver version for my Windows 10 guest. Just as I
suspected, the virtio-scsi driver can be installed and my guest is running
smooth and normal just like it has on version 0.1.110. So I think the issue
lies on the Windows 10 driver edition, which is quite strange given that
our guests are actually WIndows 10 not Windows 8.1 guests. Can you try that
also in your guest machine? Please do some backup first if necessary. :)

Best regards,
Okky Hendriansyah
