...ct a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out.

Hi, We are hitting a deadlock on libvirt on 0.9.4 version.

...at doesn't work. I wonder if we cannot do what we are doing usually when spawning qemu processes: fork() + exec() instead of relying on -daemonize which is broken. BTW: you can verify that qemu did not deamonize itself by consulting the libvirtd log: 2017-04-30 16:19:36.633+0000: 886: debug : virCommandRunAsync:2451 : Command result 0, with PID 962 This means, that PID 962 is qemu. However, when going daemon double fork is needed, therefore 'pgrep qemu' should print different number than 962. But I guess it doesn't, does it? Michal

I have installed OVS from sources using the installation steps mentioned on this link: http://docs.openvswitch.org/en/latest/intro/install/general/ I had installed libvrt, KVM, QEMU and all the necessary packages using apt-get. My KVM-QEMU hypervisor has been running well. To add a VM with the port attached to OVS bridge I changed the XML domain file as per the instructions on this page:
