Getting windows virtio mounted/installed for KVM

There might be an easy answer to this. I have exhausted my search on google for a solution. Here's my problem.

I need to get Windows working on a KVM vps with virtualizor CP. As I get into windows installation in VNC, there's the mandatory driver installation requirement, as HDD is in virtio. There seems to be 2 solutions:

Mount the virtio iso in the CD drive by unmounting Windows ISO and proceed with driver installation.
Create a secondary CD drive and mount the virtio iso there.

Well, 1st step never seems to work. If I unload the Windows iso and load the virtio iso, it never reflects back in the VNC.

Second step I have yet to be successfull. I try to create a second IDE CD ROM drive via virt-manager but the virtio (virtio-win-0.1-30.iso) iso is never listed in there, whereas i specially placed it in /var/lib/libvirt/images folder.

Any suggestions on where I screwed up?

The normal way to do this installation is:

Create the VM with a virtualized IDE disk, not a virtio disk.

Before running the installation, choose to customize the hardware, and attach a second virtual hard drive which does use virtio.

This hard drive need only be a temporary drive; it could be a tiny 1GB blank something or other.
Install Windows. (I presume you need no help with this.)
Attach the ISO image containing the virtio drivers.
You'll be notified by popup of hardware for which drivers failed to install. Click on it, or enter Device Manager yourself.
Right click on SCSI Controller, and choose Update Device Driver. Choose to Browse my computer for driver software.
Click Browse, then navigate to the \win7\amd64 folder on the virtual CD, and then click OK. Click Next.
The Red Hat VirtIO SCSI controller driver will be detected. Install it.
Shut down the VM.
Detach the second virtual hard drive. Optionally, delete it. It was temporary, after all.
Select the first virtual IDE hard drive, expand Advanced options, change the Disk bus to Virtio, then click Apply.
Start the VM.
