Aris,
From the output of show vhost, the memory regions is 0. The connection between
VPP vhost-user and QEMU virtio_net driver does not have a happy ending.
Memory regions (total 0)
Prior to launching the VM, turn on debug using "debug vhost-user on" in VPP to
see more details on the messages exchanged.

Hi Steven,
Yes the vhost-user is connected to a CSR 1k launched as VM by QEMU
(version 2.11.1).
I have appended the following lines to the xml configuration of the vm
</interface>
<interface type='vhostuser'>
<mac address='00:00:00:00:00:01'/>
<source type='unix' path='/var/run/vpp/vm1_1.sock' mode='server'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08'
function='0x0'/>
</interface>
<interface type='vhostuser'>
<mac address='02=0:00:00:00:00:02'/>
<source type='unix' path='/var/run/vpp/vm1_2.sock' mode='server'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09'
function='0x0'/>
</interface>
The show vhost returns:
