For these, we are given a socket path which is then created by QEMU and to which OpenVSwitch connects to and creates an interface. Because of this, we don't know the name of the interface upfront (when starting QEMU) and have to use the path to query OpenVSwitch later (using ovs-vsctl). What I intended to use was: ovs-vsctl --no-headings --columns=name find Interface options:vhost-server-path=$path But what my code does is: ovs-vsctl --no-headings --columns=name find Interface options:vhost-server-path=path and it's all because the argument to the function is named "path" which I then enclosed in double quotes while it should have been used as a variable.
