[Users] Migration issues with ovirt 3.3

Hi, I'm running ovirt-engine 3.3 in a server with fedora 19, also two host with fedora 19 running vdsm and gluster. I'm using the repositories like it say's here: http://www.ovirt.org/OVirt_3.3_TestDay with enable the [ovirt-beta] & [ovirt-stable] repos and disable the [ovirt-nightly] repo. I've configured a datacenter with glusterfs active an the two Host. I've installed a VM and when I do a migration it fails with the message *"VM pfSense1 is down. Exit message: 'iface'."* and the VM reboots. Also if i try to make an snapshot the VM with the Save memory it fails with the message *"VM pfSense1 is down. Exit message: Lost connection with qemu process."* If I make an snapshot without the Save Memory checked it works. I've tried to restart the libvirtd service but it's still happening. Before this I've tried the cluster with NFS storage and have problems with migration too, but the error messages were differents. Now I'm trying with gluster because this is what i want to use. Could you give me any hint about this? Regards! Emiliano
