QEMU Virtio-net-pci rev 01

RouterOS Virtualization
1

Hello!
CHR 6.47.8 on Centos Stream, qemu-kvm version 4.2, the network interface model is virtio
The RouterOS resources-pci page shows that device is: “unknown device (rev: 1)”. Older version of qemu uses rev 0 and mikrotik can use it.
Somebody can help me?

In 7.1 beta3 devices are detected normally and the network interface is visible!
