At the moment none I guess. The message is that the client cannot find a driver. I have virtio-win-0.1-74.iso and virtio-win-0.1-81.iso on the hypervisor host. How do I get the driver from there into the guest? Does the client have access to the hypervisor's file-systems? Do I mount the ISO as a cd-rom in the guest? How is that done? In virt-manager? Is there a document somewhere that I can get an idea on how this is supposed to work?

James,

I don't know if help is still needed.

Trust me. I am always in need of help.

You can mount the iso via virt-manager if you have (or create) a virt-storage-pool.

If you can reboot the client you could edit /etc/libvirt/qemu/virtclientname.xml and add <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/opt/isos/virtio-win-0.1-81.iso'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> to <devices>

(if your client already has more than 2 drives attached, change target dev hdc to hdd or ...)

You can switch your storages to virtio too, I did it in the past but fail to find my notes.

They are already virtio.

I think that the steps on this page are correct: http://setdosa.blogspot.be/2013/09/moving-your-windows-guest-from-ide-to.htm...

And, of course, work on a snapshot or at least have a copy of your client.

If you need help to change the driver in Windows I suggest we take this off-list since some are very allergic to Microsoft.

At the moment all I am looking for is how to use the CentOS tools to mount a guest system. So I think that probably falls in the scope of this list. If (when) I get into trouble on the Win side of things then I will take you up on your kind offer.

Per your suggestion I used virt-manager to open the guest and added a hardware device. I selected the option "Select managed or other existing storage", browsed for the virtio-win.iso and set the Device type to IDE CDROM with storage type 'raw'. I started the guest and the new CDROM shows in the hardware list.

I will see how it goes from there.

Thanks again,
