how to use tinc with vsock (for KVM/QEMU)

[mabra]

So far I remember, TINC may use different types of sockets, specified
in "DeviceType".
What to do to use VSOCK?
This would make TINC able to connect to qemu/kvm gest from outside.
Or how to use socat to bridge a host-running tincd to vsock?
Are there examples?
Thanks.

Hi, vsock is not meant for network communication, it's meant as a communication channel between guest agents and hypervisor services. If you want tinc on the host to connect to a network interface inside a guest, then use DeviceType multicast, vde or tap in combination with QEMU's -netdev socket, vde or tap respectively.

Thank you for your reply.
"If you want tinc on the host to connect to a network interface inside a guest"
Exactly what I want.
I want me to prevent to have a TINC interface inside the guest, but inject packets to the LO(!) interface of the guest. I considered the "mention" of socket in the TINC docs to think, "if socket why not vsock" and I have not heared about "netdev socket" before.
I started considering socat, but for your mentioned uses, are there probably any examples, where VDE is too less described to be ussable for me (and requires this additional software) ??
