Re: Problems with Windows on KVM machine

I'm not an expert on this, but here is what I would try:

1. Are you using the latest virtio drivers on your Windows guest(s)?
     http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/

2. Is there any particular reason you use CentOS 6.4 on your storage server?
     I would update it to CentOS 6.5 so you would have matching Linux 
kernels on both of your systems.
