[libvirt-users] Trouble creating virtio-serial device

Hello, I've running Ubuntu-14.04 as my host and my guest. I've been trying to get guest to host communication set up by configuring a virtio-serial device. My xml file contains: <channel type='unix'> <source mode='bind' path='/home/dave/vm1.agent'/> <target type='virtio' name='vm1'/> </channel> When I start up the VM, I get the following error: error: Failed to create domain from vm1.xml error: internal error: process exited while connecting to monitor: qemu-system-x86_64: -chardev socket,id=charchannel0,path=/home/dave/vm1.agent,server,nowait: Failed to bind socket: Permission denied qemu-system-x86_64: -chardev socket,id=charchannel0,path=/home/dave/vm1.agent,server,nowait: chardev: opening backend "socket" failed dmesg shows what appears to be an apparmor denial for mknod: [250108.632450] type=1400 audit(1415994657.679:152): apparmor="DENIED" operation="mknod" profile="libvirt-2fd2ec54-f644-228e-08ba-297c8b304153" name="/home/dave/vm1.agent" pid=21856 comm="qemu-system-x86" requested_mask="c" denied_mask="c" fsuid=112 ouid=112 I can add a line to /etc/apparmor.d/abstractions/libvirt-qemu similar to: owner /home/dave/vm1.agent rw, After restarting apparmor, this gets rid of the apparmor complaint, but I still get the same error from 'virsh create vm1.xml' when trying to create the VM. Any suggestions for how to fix this? Thanks, ~Dave
