[libvirt-users] vhost-net requested but could not be initialized

I am using a custom qemu to launch a vhost enabled VM. The qemu doesn't use
the default "/dev/vhost-net" directory as character device. Due to this I
am getting the error:

qemu-system-x86_64: -netdev
type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on: vhost-net
requested but could not be initialized

​Is there a way to tell libvirt to ​avoid using the default /dev/vhost-net
file?

I have tried using the pass-through arguments but libvirt still processes
the command and throws the error.

PS: I can successfully create a vhost VM using qemu command-line, so this
is a libvirt issue.
