hi,all
when I try to migrate `vm0` from (192.168.1.102) to another
host(192.168.1.200), the name `ubuntu1204` is 192.168.1.200's hostname.
command is :
`sudo virsh migrate --live vm0 qemu+tcp://192.168.1.200/system`
the error is : unable to connect to server at 'ubuntu1204:49157':
Connection refused.
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_mi...
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?
Otherwise, figure out how to add open ports to your firewall; but as I'm
not an Ubuntu user, I can't really say how to do that on your system.
version:libvirt:0.9.8
system:ubuntu1204
thanks in advance for any reply.
