virtio network

I don't know what kind of hardware card the original host (L0) has. My host Proxmox (L1) has a Virtio network card. If I assign Virtio network cards to my guests (L2), the cards are visible in guest OSs (Windows and Debian), but does not work. Cannot even ping the Vmbr0 interface on the host...
