I use fedora 23 with kernel 4.2.5 to run a win10 vm using qemu/kvm with vga passthrough (vfio).
I purchased a raid pci card, the problem is got is the compatibility for the driver stop at kernel 4.0.4. Is it possible to downgrade the kernel to install the driver?
If I do will I still be able to run my virtual machine without changing everything?
