I use bridged network and its fine xept one thing - its 100 mbit. What i need is 1 Gbs link(my network card allows that). Seems to fully utilise nw card i need to install virtio network device, then drivers for it from Windows and be a happy. I found this how-to http://www.linux-kvm.com/content/tip-how-setup-windows-guest-paravirtual-network-drivers , but i dont understand how to make virtio device available for guest if i dont start machine manually via command line, but want to incorporate it into xml.

virt-manager doesn't yet support adding a virtio nic to
an existing guest, but we will soon. You'll have to make
the changes via the command line.

What you will want to do is:

- stop your vm
- virsh dumpxml YOURVM > xml

- edit xml, and add:

  <model type='virtio'/>

  to the <interface> block.

- virsh define xml
- start the vm

Thanks,
