good day, i am trying to create domain via virDomainDefineXML. and my program 
hanging, also i failed to caonnect to libvirt daemon with virt-manager after 
this, only killing libvirtd via SIGKILL and restarting it solveing hang (i 
mean after restart i able to connect with virt-manager), i using following 
domain xml

<?xml version="1.0" encoding="UTF-8"?>
<domain type="kvm">
  <tittle>Automatically created domain with default configuration</tittle>
  <name>vm1</name>
  <description>no description</description>
  <os>
    <type>hvm</type>
    <boot dev="cdrom"/>
    <boot dev="hd"/>
  </os>
  <vcpu>1</vcpu>
  <memory unit="MB">512</memory>
  <cpu model="host-model">
    <topology sockets="1" cores="1" threads="1"/>
  </cpu>
  <clock offset="localtime"/>
  <devices>
    <graphics type="vnc" autoport="yes" password="admin"/>
    <channel type="unix">
      <source mode="bind" path="/var/run/vm1.sock"/>
      <target type="virtio" name="org.guest_agent.0"/>
    </channel>
