Hello community,

  I am looking for a way to configure vhost-user-vsock using libvirt, but looks like it is not written in doc. How can I use vhost-user-vsock using libvirt? Thank you.

Libvirt has basic support for vsock: https://libvirt.org/formatdomain.html#vsock For instance the following: <vsock model='virtio'> <cid auto='no' address='4'/> </vsock> will get you: -device '{"driver":"vhost-vsock-pci","id":"vsock0","guest-cid":4,"vhostfd":"6789","bus":"pci.0","addr":"0x7"}' But, I don't think we have vhost-*user*-vsock implemented yet.
