Dracut is simply a more modern version of mkinitrd. It's just a script to prepare an initramfs for you - not a replacement for initramfs.

You'll need to have the vfio_pci modules in the initramfs with the device_ids in the /etc/modprobe.d/vfio_pci stuff included in the initramfs. It's all in the guide on vfio.blogspot.com.

Dracut is just an easy tool to prepare an initramfs. There's also "better initramfs" on github but I still like dracut. If you're really adventurous you can build and compress the file system yourself - I'll be migrating to this approach myself soon as dracut includes some "extras" that I don't really need.

The most important thing is to choose your hardware very carefully. Read everything on that site. As long as you have compatible hardware (most stuff > 2013 is) the software side of it is straightforward. The UEFI approach is very stable - the previous seabios / vga approach was a little flaky for me but I was also on an old patched dirty software stack.
