Open Stack

and I am not sure  listen_addr = "10.10.10.182", the other nodes could access it . "0.0.0.0"?

  After making the following changes, the libvirtd daemon failed to start...  but if i remove "-f /etc/libvirt/libvirtd.conf" from /etc/default/libvirt-bin,  the livbirted daemon can start after running 'service libvirt-bin restart.
  
  cat /etc/default/libvirt-bin
 # Defaults for libvirt-bin initscript (/etc/init.d/libvirt-bin)
 # This is a POSIX shell fragment
  
 # Start libvirtd to handle qemu/kvm:
 start_libvirtd="yes"
  
 # options passed to libvirtd, add "-l" to listen on tcp
 libvirtd_opts="-d -l -f /etc/libvirt/libvirtd.conf"
  
  root at compute1:/etc/libvirt# cat  /etc/libvirt/libvirtd.conf|grep -v "#"
  
 listen_tcp = 1
  
 tcp_port = "16509"
  
 listen_addr = "10.10.10.182"
  
 unix_sock_group = "libvirtd"
  
 unix_sock_rw_perms = "0770"
  
 auth_unix_ro = "none"
  
 auth_unix_rw = "none"
  
  
 Note:10.10.10.182 is the compute node's internal  IP.

 Hello,
  
 I was trying to migrate one instance from  the compute node compute2 to another node compute1, but failed, the  nova-compute.log said compute2 failed to connect the 16509 port on compute1, i  noticed that the 16509 port is not opened on compute1, is there any additional  configuration for Live-Migration ? Which service listens on port 16509  ?
  
 The hypervisor is KVM.
