Proxmox Virtio

Hi,

We're using NOC-PS to create Proxmox VPS but for some reason both the NIC and the HD are VirtIO. This is an issue for some of the OS we deploy as the drivers are not available.

So 2 questions

1) Where are the official SIGNED server 2008 and 2012 VirtIO drivers for storage and network
2) Is there anyway to change the official deployment? (ie change network to e1000 intel and harddisk to sata?)
