I have CCed the libvirt mailing list, since KVM is a component here but your question seems to be mainly about libvirt, virt-manager, virt-install, etc.
Apologies for posting to the wrong list, I assumed it would be KVM related as the guest could run but could not see the drive. More information 1. install guest with /dev/sdxx as virtio device (the problem case) - installer does not see any drive - load drivers on Redhat virtio "cdrom" - installer still does not see any drive 2. Install guest with qcow2 disk file as virtio device - as previous scenario but installer see drives after installing drivers 3. install guest with qcow2 disk file as IDE device - complete installation - add /dev/sdxx as virtio disk - goto Windows Device Manager and update virtio driver for unknown controller - Windows see /dev/sdxx after driver installed
It sounds like you want an NTFS partition on /dev/sda. That requires passing the whole /dev/sda drive to the guest - and the Windows installer might overwrite your GRUB Master Boot Record. Be careful when trying to do this.
Yes, I wanted to give Windows its own native partition that could be read directly if I had to yank the disk and put it into a Windows machine. Is this why #3 works but not #1? That as long as I want to install Windows directly to an NTFS partition on/dev/sda, it is required that I pass the whole drive to Windows?
