I tired to install newer version of qemu-kvm (2.1.0-2.9-x86_64) through rpms but the following rpms are not all available
So I changed from Centos 6.6 to Ubuntu 14.04 because the environment setup is much easier, some bugs had been fixed but the migration did not work at all
and I got this error message "error: internal error: unable to execute QEMU command 'drive-mirror': Failed to connect to socket: Invalid argument"
I thought it's security issue so I disabled the SELINUX and I make some firwall configuration but the problem persist:
sudo iptables -A INPUT -p tcp -m multiport --ports 16509 -m comment --comment "libvirt" -j ACCEPT
sudo iptables -A INPUT -p tcp -m multiport --ports 49152:49216 -m comment --comment "migration" -j ACCEPT
Have you any idea what is the reason behind this problem??
