I recently made a QEMU/KVM (q35) Windows 10 virtual machine on a Debian 9 host. I've set up the Windows 10 host to use two RAID 0 arrays:
- One 550 gb array (using two 550 drives)
- One 2 tb array (using two 2 tb drives)
I used the VirtIO SCSI drivers to install the raid arrays.
Everything seems to be working fine except that there is a warning message in Windows 10 Device Manager:
Under "Portable Devices", there is a listing for "C:\Program Files\Games" and it has a status of
"This device cannot start. (Code 10)". When I added the 2TB raid array in windows, instead of assigning it a drive
letter, I assigned it to "C:\Program Files\Games"
I'm just guessing here, but could it be:
- because I installed the second RAID array to a file folder instead of to a drive letter?
- because my motherboard only supports IOMMUv1?
- because of something else entirely?
In case it helps, here is a copy of vm xml:
