Indeed, when using native migration, you have to open a rather large range of ports that qemu might want to use. http://wiki.libvirt.org/page/FAQ#What_setup_is_required_for_QEMU.2FKVM_migration.3F > > however,when I try to virsh connect to 192.168.1.200 by tcp is no problem. http://libvirt.org/migration.html gives more details on how to do live migration; in particular, you may want to try using --p2p to avoid having to open any ports for qemu. > > I dont know what the port 49157?how to fix it?
