The problem with networking for VirtIO drivers

[perrfect]

Hello.
I'm using pfSense 2.6.0 on oVirt. And have a problem with the VirtIO drivers for the network.
I'm getting an error after installation:

Default interface not found -- Running interface assignment option.
No interface found!
pfSense cannot continue without at least on Network Interface Card.

With driver e100 working fine.

I've tried Disable Hardware Checksum Offloading via GUI and then switched on to VirtIO from e100, but the same error.
Can please help me?

Whatever virtio devices are being created by ovirt they are not supported by the operating system.

VirtIO devices on Proxmox VE/KVM and so on in general work fine, though, so it's most likely something in your hypervisor or hypervisor settings.
