When doing Live-Migration, the error message said failed to connect
'compute1:16509', compute1 can be resolved to 10.10.10.182 on any node.

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@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.

check the port in /etc/libvirt/libvirtd.conf :)

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.
