Hi,

It looks like the author of this package decided to include the vioserial driver directly. The RHEL package does this only for NetKVM, QXL, vioscsi and viostor, everything else is available in the .ISO. The rationale is that all but boot-critical drivers are expected to be installed by attaching the .ISO to the VM anyway.

If you need to extract the vioserial driver on the host, you can do so by running:

$ sudo mount -o loop /usr/share/virtio-win/virtio-win.iso /mnt/myiso
mount: /dev/loop0 is write-protected, mounting read-only
$ ls -l /mnt/myiso/vioserial/2k8R2/amd64/
total 3094
