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

- qemu-2.1.0-2.9-x86_64.rpm

- qemu-kvm-2.1.0-2.9-x86_64.rpm

- qemu-common-2.1.0-2.9-x86_64.rpm

- qemu-kvm-tools-2.1.0-2.9-x86_64.rpm

- qemu-debuginfo-2.1.0-2.9-x86_64.rpm

- qemu-system-x86-2.1.0-2.9-x86_64.rpm

- qemu-guest-agent-2.1.0-2.9-x86_64.rpm

- qemu-user-2.1.0-2.9-x86_64.rpm

- qemu-img-2.1.0-2.9-x86_64.rpm 

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??

Thanks for your answer,

1) In this case i'm not using shared storage, the migration is happening
between two non-shared storage with full disk copy
2) I already created the file with same size, and the vm
works properly after a restart, my problem that it remains paused and I
can't resume it until it's rebooted.
3) I'm using qemu-kvm 1.0

This may be the root of problem. That's nearly 3 years old qemu.
