Hi everyone

It is not an issue, but I am wondering how I can install a Windows guest in webvirtmgr?

When I try to do a general installation steps it looks like W8.1 does not see a virtual disk. Why? What I am missing?

Thank you.

When you create the virtual machine uncheck VirtIO. To get VirtIO support in windows you need to install extra drivers.

Here you can find the source for the drivers and links to binary builds.

Thank you.
However, your answer leads me to other question. What are the advantages of the virtio drivers in the Windows guest perspective?

from here

Para-virtualized drivers enhance the performance of guests, decreasing guest I/O latency and increasing throughput to near bare-metal levels. It is recommended to use the para-virtualized drivers for fully virtualized guests running I/O heavy tasks and applications.

Details on what virtio does

After you've installed windows you can change the storage and network devices to use virtio. In the current version of webvirtmgr you can do that by editing the libvirt xml in "Instance->Settings->XML"

For linux guests, virtio should work out of the box if it's a modern distribution with a stock kernel.

Hi I just play a bit with virtio drives and windows. And I think I have some kind of request. According this topic:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Host_Configuration_and_Guest_Installation_Guide/form-Virtualization_Host_Configuration_and_Guest_Installation_Guide-Para_virtualized_drivers-Installing_with_a_virtualized_floppy_disk.html

To install virtio drivers during windows installation I need to have a floppy disk or an extra CD-ROM.

Is it possible to add an extra CD-ROM in instance>Settings>Media>[Add extra CD-ROM]
extra cdrom

Thank you.

I know another way in XML find:

<disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <target dev='hda' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='1' target='0' unit='1'/>
    </disk>

copy this to a new paragraph and change it like this:

    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <target dev='hda' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='2' target='0' unit='2'/>
    </disk>

It should work, but I didn't test it. In any way it is less user-friendly than just a button add new cd-rom or hdd.

You are right TDron an add new cd-rom button will be the best solution
....will probably ask @ retspen to add it as a new feature

As far as I solved the problem with windows installation the topic is closed now.
