CAN virtualization

Dear Users, I use KVM with libvirt 9.0.0. The host and guest OS-es are also AGL needlefish images. I am currently trying to virtualize a CAN driver and provide virtual machines access to the physical CAN channels. I started with the virtual network handling as CAN interface is a network interface, I tried to find analogies, solutions like "traditional" network handling but it did not work. I also tried out to define a nodedev device via .xml config file. The interesting thing is, that when I list all the available nodedev devices with 'virsh nodedev-list', I can see 'net_can0' and 'net_can1' on the output as 'net' type device but I cannot attach these devices to the guests, and I do not know how to define it in the guest .xml file. I tried out many different things, but when I try to add it as a 'hostdev' device with different mode and type settings, I always get an error (e.g. not a PCI device or not supported device type etc.). It would be long to write down all the configurations I tried out, so my first question would be that does anybody know how could I provide access to guests to the physical CAN interfaces? The aim is to be able to send CAN messages from guest OS-es. If no direct access is possible, it would be also OK to have access to virtual CAN interfaces on the host and then transfer messages to the physical CAN channel.
